Stratospheric Ozone – Its role in the Earth system
“Without a protective ozone layer in the atmosphere, animals and plants could not exist, at least upon land. It is therefore of the greatest importance to understand the processes that regulate the atmosphere's ozone content.” This quote from the Swedish Royal Academy of Sciences – announcing the 1995 Nobel Prize for Chemistry to Paul Crutzen, Mario Molina, and F. Sherwood Rowland – remains relevant to this day. The more we study stratospheric ozone, the more we realise its importance not only

Anthropogenic aerosol and the Asian summer monsoon
Almost half of the world's population rely on the Asian summer monsoon (ASM) precipitation for agriculture, energy, industry, and local water resources. Small changes in the onset, intensity, and duration of the ASM can result in considerable socio-economic impacts. An observed drying trend in ASM precipitation in the latter half of the 20th century opposed the anticipated impact of increasing greenhouse gas emissions, and has largely been attributed to increases in anthropogenic aerosol. Recent

MethaneSAT and MethaneAIR: Mitigating methane emissions from the oil and gas sector.
Methane emissions have major impacts on atmospheric composition and radiative forcing of climate change. The MethaneSAT satellite, and its companion aircraft instrument, MethaneAIR, are new imaging spectrometers intended to contribute in a major way to solving this important problem. MethaneSAT will provide measurements on regional scales (~200 x 200 km) with high spatial resolution (~130 m x 450 m) and precision, while MethaneAIR has a swath width of 4.5 km and pixel size of 5 x 25m. The missio

Global wind profiles from space with the first wind lidar in space on ESA´s Aeolus mission
The European Space Agency (ESA)’s Earth Explorer Aeolus was launched in August 2018 carrying the world’s first spaceborne wind lidar, the Atmospheric Laser Doppler Instrument (ALADIN). ALADIN uses a high spectral resolution Doppler wind lidar operating at an ultraviolet wavelength of 355 nm to measure profiles of line-of-sight wind component. ALADIN samples the atmosphere from 30 km altitude down to the Earth’s surface or to the level where the signal is attenuated by optically thick clouds. Bes
