Multi-Decadal Nitrogen Dioxide and Derived Products from Satellites (MINDS) Datasets Released by NASA GES DISC and Their Applications for Air Quality

Nitrogen dioxide (NO2), a pervasive air pollutant, comes from vehicles, power plants, industrial
emissions, and off-road sources such as construction or lawn and gardening equipment. The
NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) curates many
remote sensing datasets with NO2 retrievals, which have been utilized for air quality research and
applications. The remotely-sensed datasets include those generated by the Ozone Monitoring
Instrument (OMI) on the Aura satellite, the TROPOspheric Monitoring Instrument (TROPOMI)
onboard the Copernicus Sentinel-5 Precursor (S5P), and the Ozone Mapping and Profiling Suite
(OMPS) Nadir-Mapper (NM) instrument on the Suomi National Polar-orbiting Partnership (S-
NPP). In collaboration with the NASA Making Earth System Data Records for Use in Research
Environments (MEaSUREs) Multi-Decadal Nitrogen Dioxide and Derived Products from
Satellites (MINDS) project, the GES DISC recently released MINDS datasets. The NASA
MEaSUREs MINDS project aims to develop long-term NO2 global data records by adapting a
consistent retrieval algorithm to multiple instrument measurements. Long-term data records will
be achieved by applying consistent retrieval approaches to multiple satellite instruments,
including OMI (2004 - ); the Global Ozone Monitoring Experiment (GOME, 1995-2011)
onboard the second European Remote Sensing satellite (ERS-2); the Scanning Imaging
Spectrometer for Atmospheric Cartography (SCIAMACHY, 2002-2012) onboard the
ENVIronmental SATellite (ENVISAT); GOME-2 on the Meteorological Operational satellites
(MetOp-A and MetOp-B, 2006 - ); and TROPOMI onboard the Copernicus S5P (2017 - ).

The long-term record (1995 to present) of MINDS datasets makes them very useful for air
quality trend studies. Some MINDS datasets with high spatial resolution of only a few kilometers
can be used for air quality research and applications at regional scales. In this presentation, we
will introduce all of the MINDS products and services, and demonstrate use cases of MINDS
data for studying air quality. We will also present a few other NO2 datasets acquired from
NASA’s Health and Air Quality Applied Sciences Team (HAQAST), to be archived and
distributed by the GES DISC, and highlight some of their applications for air quality and health.
