Discrete-wavelength DOAS NO.sub.2 slant column retrievals from OMI and TROPOMI

The use of satellite NO.sub.2 data for air quality studies is increasingly revealing the need for observations with higher spatial and temporal resolution. The study of the NO.sub.2 diurnal cycle, global sub-urban-scale observations, and identification of emission point sources are some examples of...

Description
Summary:	The use of satellite NO.sub.2 data for air quality studies is increasingly revealing the need for observations with higher spatial and temporal resolution. The study of the NO.sub.2 diurnal cycle, global sub-urban-scale observations, and identification of emission point sources are some examples of important applications not possible at the resolution provided by current instruments. One way to achieve increased spatial resolution is to reduce the spectral information needed for the retrieval, allowing both dimensions of conventional 2-D detectors to be used to record spatial information.
