Abstract:
We will present comparisons between measurements of NO2 abundance in the troposphere using both ground and airborne instruments developed for air quality research, focusing on the high spatial resolution requirements of next generation geostationary sensors. The GCAS and GeoTASO aircraft sensors are capable of retrieving NO2 at sub-1km spatial sampling that meets the sensitivity requirements of the TEMPO and GEMS science products. These instruments were flown simultaneously during a portion of both the Houston and Denver Discover-AQ deployments and GeoTASO will be flown during the KORUS-AQ deployment. An assessment will be made of the absolute agreement between these instruments at various spatial scales and under a variety of viewing and surface conditions. The ground based PANDORA network measurements will be used to assess consistency between the instruments.
