Brewer-Wilson Seminar Series

The Brewer-Wilson seminar series is the EAPP group's regular Friday lunchtime seminar series. Alan Brewer was a faculty member of this department from 1962-1977 and a founding member of the Atmospheric Physics Group with interests in both atmospheric instrumentation and dynamics. His work with Dobson at Oxford from 1948 to understand stratospheric water vapour, resulted in the Brewer-Dobson circulation theory. He also developed the Brewer spectrometer for measurements of ozone, a fore-runner to the MAESTRO instrument, which underwent characterisation at our space test facilities in 2003. Over his illustrious career he supervised both John Houghton and Tom McElroy. J. Tuzo Wilson was a faculty member of this department from 1946-1993 and is credited as the "father" of plate tectonics theory. He pioneered the use of air photos in geological mapping, was responsible for the first glacial map of Canada, was the 2nd Canadian to fly over the North Pole, and was a leader in the research of glaciers, mountain building, the geology of ocean basins and the stucture of continents.

Seminar aims

The Brewer-Wilson seminars provide EAPP graduate students, postdocs and research associates with an opportunity to present their work to their colleagues in an informal setting. The seminars give presenters a chance to get feedback on research and presentation skills and to gain confidence for formal oral presentations. Attendees benefit by gaining a broad perspective on the theoretical and experimental work of the EAPP Group. The Brewer-Wilson series has a formative rather than an evaluative purpose: that is, it is not meant as a formal tool for evaluating students in the EAPP Group, but primarily as a means of training students in the group.

All members of the EAPP Group, especially students, postdocs, and research associates, are expected to be actively engaged in the series, by their attendance and participation. Attendance is especially encouraged if the research topic is outside your area of study! Faculty will attend as their schedules permit.

The series is held at lunchtime on Fridays, during the regular undergraduate fall and spring terms. All graduate students in the EAPP Group, apart from M.Sc. students and first year direct entry Ph.D. students are expected to regularly present in the series. Each week's seminar will consist of a 35-40 minute talk followed by 5-10 minutes for questions. A short abstract for the upcoming talk will be circulated at the beginning of each week. 

The Brewer-Wilson series is convened by students in the EAPP Group who organize the schedule in consultation with the faculty. The 2024-2025 conveners are Anson Cheung and Eylon Vakrat.

Where and when

The 2024-2025 Brewer-Wilson Seminar Series will be an in-person seminar and will be held in MP606, on the 6th floor of the Burton Tower in McLennan Physical Laboratories ( 60 St. George Street). All seminars take place at noon on Friday. The title and the abstract will be distributed at the beginning of each week.

Bromine release in the high Arctic: what is the role of aerosols?
Exponential build-up of bromine in the polar troposphere is linked to severe multi-day ozone depletion events in springtime. Recent research suggests that saline snowpack and aerosols are the main sources of bromine, but the exact mechanisms of, and conditions required for these ‘bromine explosions’ are not well understood. The two main sources of aerosol in the Arctic spring are transported pollution (Arctic haze), and larger particles produced from the open ocean or potentially through the sublimation of blowing snow. Both types of particles are rich in sea salt and could contribute to bromine release. Eureka, Nunavut (80°N) is an excellent location to monitor springtime bromine explosions and aerosol concentrations. Profiles of bromine monoxide (BrO) retrieved from Multi-AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) measurements show that there is no clear correlation between BrO concentration and haze aerosol. However, larger aerosols correlate well with observed BrO, indicating that these aerosols are likely a source of bromine. This talk investigates the potential direct and indirect links between bromine activation and aerosols in the high Arctic

High-frequency observations of temperature and dissolved oxygen reveal under-ice convection in a large lake
Detailed observations of thermal structure over two winters in a large lake reveal the presence of large (10-20 m) overturns under the ice, driven by diurnal solar heating. Convection can occur in the early winter, but the most vigorous convection occurred near the end of winter. Both periods are when our lake ice model suggest thinner ice that would have been transparent. This under-ice convection led to a deepening of the mixed layer over time, consistent with previous short-term studies. During periods of vigorous convection under the ice at the end of winter, the dissolved oxygen had become super-saturated from the surface to 23 m below the surface, suggesting abundant algal growth. Analysis of our high-frequency observations over the entire winter of 2015 using the Thorpe scale method quantified the scale of mixing. Furthermore, it revealed that changes in oxygen concentrations are closely related to the intensity of mixing that could be influenced by climate change or the increased input of salt into the lake. I will briefly present an overview of some of the basics of physical limnology before presenting our results.

Comparing the robustness of the coupled circulation response to high and low latitude forcing
Four fully coupled climate models, CESM1, CanESM2, CNRM-CM5 and GFDL-CM3Z are used to isolate the impact of Arctic sea ice loss on the atmosphere. In all models, Arctic sea ice is melted in isolation from the effects of external radiative forcing. However the method through which this melting is achieved, as well as the radiative forcing protocol, differs between the sets of experiments. Nonetheless, several aspects of the wintertime response are remarkably robust. Arctic sea ice loss in coupled models produces warming that is strongest over the Arctic Ocean and high latitude land masses alongside a weak cooling over eastern Eurasia, a dipole pattern in sea level pressure with lower pressure over North America and higher pressure over Eurasia, a strengthening of 850 hPa zonal winds in mid-latitudes along with a weakening on the poleward side, and an increase in precipitation over northern high latitudes. Because there are different amounts of warming at lower latitudes between the models, a pattern scaling approach is used to separate out the part of the pattern that scales with low-latitude warming and the part that scales with sea ice loss. The similarity in the part that scales with sea ice loss remains after applying pattern scaling, but the part of the pattern that scales with low-latitude warming is model-dependent.

Modelling urban anthropogenic 12CO2 and 13CO2 in the Greater Toronto Area
Even in urbanized regions, carbon dioxide (CO2) emissions are derived from a variety of biogenic and anthropogenic sources and are influenced by atmospheric transport across borders. As policies are introduced to reduce the emissions of CO2, there is a need for independent verification of emissions reporting. In this work, we use carbon isotope (12CO2 and 13CO2) simulations in combination with atmospheric measurements to distinguish between CO2 sources in the Greater Toronto Area (GTA). This is being done by developing an urban δ13C framework based on CO2 emissions data and forward modelling. We developed the UofT/ECCC inventory, a CO2 inventory for southern Ontario at a very fine spatial and temporal resolution (0.02ox0.02o and hourly, respectively). The inventory is run with the GEM-MACH chemistry transport model and results are used in our framework in combination with region-specific δ13C signatures of the dominant CO2 sources; the product is compared against highly accurate 13CO2 and 12CO2 ambient data made at sites across southern Ontario. The strength of this framework is its potential to estimate contributions of both locally-produced and regionally-transported CO­2. Locally, anthropogenic CO­2 in urban areas is often derived from natural gas combustion (for heating) and gasoline/diesel combustion (for transportation); the isotopic signatures of these processes were measured to be significantly different (approximately d13CVPDB = -44 ‰ and -28 ‰ respectively) in the GTA and can be used to infer their relative contributions. Utilizing our δ13C framework and differences in sectoral isotopic signatures, we quantify the relative contribution of CO2 sources on the overall measured concentration and assess the ability of this framework as a tool for tracing the evolution of sector-specific emissions.

Characterizing dispersion due to moisture using multi-pole Debye model
Abstract: Ground penetrating radar (GPR) is a nondestructive measurement technique that utilizes electromagnetic waves to locate targets beneath the surface. The speed of EM waves is determined by dielectric permittivity, which is often assumed to be constant within a homogeneous material. However, dielectric permittivities in real materials vary with frequency. This phenomenon, called dispersion, affects the interpretation of GPR signals. Dispersion becomes stronger with increasing moisture content in materials due to the dipolar nature of water molecules. The goal of this work is to isolate the dispersion caused by water from the dispersion inherent to material. We measure the complex permittivities of samples from a massive sulphide mine under both ambient and dry conditions. The measurements are fitted to a 2-pole and a 3-pole Debye model. Results show that dry samples can be fitted well with 2-pole model while the ambient samples require an additional pole. The relaxation time of the additional pole in ambient samples does not match to that of pure water and further experimentation with higher moisture content is needed.

Global Trends in Water Vapour
Abstract: Stratospheric water vapour is an important greenhouse gas subject to a positive feedback cycle with surface temperature. Work has been done over the last two decades to characterize its behaviour in the stratosphere, and while general consensus shows that stratospheric water vapour is increasing, the majority of studies come to this conclusion using observations from a single area and generalizing over the globe. While this works for well mixed gases, such as carbon dioxide, water vapour displays distinct patterns across the globe. In this talk I will illustrate an alternate approach, using data collected by ACE-FTS and fitting discrete regions across the globe, in an attempt to generate a more comprehensive view of stratospheric water vapour trends.

Thermohaline Instability and the Formation of North Atlantic Super Polynyas during the Glacial
Climate variability recorded in Greenland ice cores over the past 100,000 years is interspersed by a number of rapid warming events. Each warming event is approximately 10 to 15 degrees C in annual average temperature at summit Greenland. Each of these events in the climate record is also estimated to have occurred in less than a couple of decades. A modelling simulation of the glacial climate with a fully coupled climate model reveals that the initial warming event is triggered by thermohaline instability under a North Atlantic covered by sea ice. The initial instability is characterized by the formation of a wintertime glacial super polynya at the beginning of each warming event. Afterwards, the resumption of the Atlantic Meridional Overturning Circulation (AMOC) from a reduced state occurs within a couple of decades. I will describe some of the interesting physics underlying the instability.

40 years of atmospheric methane FTIR observations from a remote European site
Observation of solar radiation in the infrared have been performed since the mid-fifties at the International Scientific Station of the Jungfraujoch (ISSJ, Swiss Alps, 46.5°N, 8.0°E, 3580 m a.s.l.), in the framework of the Network for Detection of Atmospheric Change (NDACC, www.ndacc.org<http://www.ndacc.org>). Systematic monitoring of the chemical composition of the Earth's atmosphere started in 1984 by using two state-of-the‐art Fourier Transform InfraRed (FTIR) instruments, while grating spectrometers were used previously in the early 1950s, and from the mid-1970s onwards, covering 40 years of quasi-continuous solar observations. In this framework, I will discuss optimization of retrieval strategies from infrared solar observations and methane trend analysis.

Quantifying emissions of CO and NOx using observations from MOPITT, OMI, TES, and OSIRIS
We use the GEOS-Chem four-dimensional variational (4D-var) data assimilation with satellite observations of multiple chemical species to estimate emissions of CO and NOx, as well as the tropospheric concentrations of O3. In doing so, we utilize CO retrievals from The Measurements of Pollution In The Troposphere (MOPITT), O3 retrievals from the Tropospheric Emission Spectrometer (TES), O3 retrievals from the Optical Spectrograph and InfraRed Imager System (OSIRIS), and NO2 columns from the Ozone Monitoring Instrument (OMI). By integrating these data in the 4D-Var scheme, we obtain a chemical state in the model that is consistent with all of the data over the assimilation period. In this context, for example, we find that combining TES and OSIRIS improves O3, particularly in the tropical upper troposphere (by 10-20%), which leads to a reduction in the uncertainty of the NOx emission estimates. However, although assimilating multiple chemical species provides a stronger constraint on the chemical, state, there are still large uncertainties on the CO and NOx emission estimates, due to the dependence of the results on the selection of the assimilation window and how the datasets are weighted in the cost function.

Using space-based chlorophyll fluorescence and CO2 observations to constrain primary production and respiration about the boreal ecosystems
Sun-induced chlorophyll fluorescence (SIF), radiation emitted by vegetation during photosynthesis, has long been known to be a good proxy for primary productivity. However, only within the last few years have high-resolution space-based spectrometers allowed global observations of SIF. In this talk, I will examine how SIF observations from the GOME-2 satellite compare with primary productivity estimates from terrestrial ecosystem models. I will then introduce a method to combine space-based SIF observations with atmospheric CO2 observations to constrain both primary productivity and respiration in boreal terrestrial ecosystems.

Polar Low Induced Surface Ozone and HDO Depletion
Ground-based and satellite datasets were used to identify two similar polar low induced surface ozone depletion events in Eureka, Canada on March 2007 and April 2011. These two events coincident with observations of depleted HDO, indicate the condensation process during the transportation of the ozone depleted airmass. Lidar and radar measured the ice clouds and aerosol when the ozone and HDO depleted airmass arrived in Eureka. Two global chemical-climate models were used to simulate the surface ozone depletion. A global reanalysis model data and a particle dispersion model were used in this work to study the link between the ozone and HDO depletion. Observational and modelled data show these events have the distinctive feature of coincident of the strong tropospheric cyclone and intensified stratospheric vortex.

The atmospheric response to extratropical ocean warming induced by sea ice loss
Sea ice loss impacts the atmosphere by altering the surface energy balance, warming the Arctic lower troposphere, and potentially changing the large scale atmospheric circulation at mid-latitudes. A large number of studies have carried out numerical modeling experiments to isolate the atmospheric impacts of sea ice loss from other effects. These typically use an Atmospheric General Circulation Model (AGCM) forced with reduced sea ice concentrations while keeping sea surface temperatures and other forcings fixed. As the ocean cannot respond, these experiments ignore potentially important thermodynamic and dynamical feedbacks with the ocean. In this talk, I will examine the impact extratropical ocean warming caused by sea ice loss has on the atmosphere using both coupled ocean-atmosphere climate model and AGCM experiments. I will show that the extratropical ocean warming amplifies the atmospheric circulation response to sea ice loss, suggesting that previous studies using only AGCM experiments may underestimate the response.

Why are upward EP-flux and temperature positively skewed in the stratosphere?
Polar stratospheric temperatures are positively skewed, with a typical value of skewness of 0.64 in Northern Hemisphere winter, an asymmetry that determines the character of ozone climate coupling and stratosphere-troposphere interactions. This skewness is often attributed to the fact that temperatures are bounded from below by a radiative limit while dynamical wave-driven events like sudden stratospheric warmings can cause significantly larger positive anomalies. In this talk, I will examine the positive skewness of upward wave activity flux itself as a driver of the temperature distribution. I will use the ideas of linear interference to explain the positive skewness of upward wave activity flux. In particular, I will show that a nonlinear relationship between the two terms that make up the heat flux anomaly can be used to explain its positive skewness. Finally, by using a toy statistical model of wave interference in the lower stratosphere, and I will show that the westward tilt of the climatological wave is the key ingredient to obtaining a positively skewed upward wave activity flux distribution.

The mid-Pliocene CESM1 climatology
A very interesting time-period in the recent past is the mid-Pliocene (~3 Millions years ago). The configuration of the world looked much the same as today, CO2 was likely less than present day, but still the temperatures were much warmer and sea-level ~15-20m higher. If it is possible for the earth system to have such an extreme response to greenhouse gas concentrations no different from today’s, then it raises questions about the level of faith that can be put into climate model projections of only ~1 m of sea-level rise by the end of this century.
