Ethane is the most abundant non-methane hydrocarbon in the troposphere, where it impacts
ozone and reactive nitrogen and is a key tracer used for partitioning emitted methane …

The tropics is the nexus for many of the remaining gaps in our knowledge of environmental
science, including the carbon cycle and atmospheric chemistry, with dire consequences for …

Isoprene, produced by plants in response to multiple drivers, affects climate and air quality
when released into the atmosphere. In turn, climate change may influence isoprene …

Many plants, especially trees, emit isoprene in a highly light‐and temperature‐dependent
manner. The advantages for plants that emit, if any, have been difficult to determine. Direct …

Land surface changes can have substantial impacts on biosphere–atmosphere interactions.
In South America, rainforests abundantly emit biogenic volatile organic compounds …

Satellite observations are critical for air quality and climate monitoring, and for developing
the process understanding needed for reliable planning and predictions. Our current space …

Satellite measurements play an increasingly important role in the study of atmospheric
ammonia (NH 3). Here, we present version 4 of the Artificial Neural Network for IASI (ANNI) …

The hydroxyl radical (OH) is the central oxidant in Earth's troposphere, but its temporal
variability is poorly understood. We combine 2012–2020 satellite-based isoprene and …

Isoprene is a hydrocarbon emitted in large quantities by terrestrial vegetation. It is a
precursor to several air quality and climate pollutants including ozone. Emission rates vary …

Spaceborne formaldehyde (HCHO) measurements constitute an excellent proxy for the
sources of non-methane volatile organic compounds (NMVOCs). Past studies suggested …
