TEMPO was selected in 2012 by NASA as the first Earth Venture Instrument, for launch
between 2018 and 2021. It will measure atmospheric pollution for greater North America …

Satellite remote sensing of air quality has evolved dramatically over the last decade. Global
observations are now available for a wide range of species including aerosols, tropospheric …

TROPOMI satellite data show substantial drops in nitrogen dioxide (NO2) during COVID‐19
physical distancing. To attribute NO2 changes to NOx emissions changes over short …

Abstract The Geostationary Environment Monitoring Spectrometer (GEMS) is scheduled for
launch in February 2020 to monitor air quality (AQ) at an unprecedented spatial and …

Abstract TROPOspheric Monitoring Instrument (TROPOMI), on‐board the Sentinel‐5
Precurser satellite, is a nadir‐viewing spectrometer measuring reflected sunlight in the …

Mathematical modeling of atmospheric composition is a formidable scientific and
computational challenge. This comprehensive presentation of the modeling methods used …

Ozone pollution in the Southeast US involves complex chemistry driven by emissions of
anthropogenic nitrogen oxide radicals (NO x≡ NO+ NO 2) and biogenic isoprene. Model …

Satellite observations of tropospheric NO 2 columns are extensively used to infer trends in
anthropogenic emissions of nitrogen oxides (NO x≡ NO+ NO 2), but this may be …

We present a new and improved version (V4. 0) of the NASA standard nitrogen dioxide (NO
2) product from the Ozone Monitoring Instrument (OMI) on the Aura satellite. This version …

Reactive gases and aerosols are produced by terrestrial ecosystems, processed within plant
canopies, and can then be emitted into the above-canopy atmosphere. Estimates of the …
