Nitrogen dioxide air pollution, daily map (OMI/Aura, 0.25 deg)

OMI/Aura NO2 Tropospheric, Stratospheric & Total Columns MINDS Daily L3 Global Gridded 0.25 degree x 0.25 degree V1.1 (OMI_MINDS_NO2d) at GES DISC
atmosphere NASA GES_DISC Level 3 active
In plain English

What it measures. A daily global map of nitrogen dioxide air pollution at 0.25-degree resolution, broken into the lower-atmosphere (tropospheric), upper-atmosphere (stratospheric), and total columns.

How it's made. Built by adapting the OMI instrument's algorithms across multiple satellites (including OMI on Aura) to create consistent gridded NO2 records, processed to Level-3.

How & where you'd use it. Useful for tracking air pollution and emission trends over the past two decades, supporting air-quality and policy research.

Official description

As part of the NASA's Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, this project entitled “Multi-Decadal Nitrogen Dioxide and Derived Products from Satellites (MINDS)” will develop consistent long-term global trend-quality data records spanning the last two decades, over which remarkable changes in nitrogen oxides (NOx) emissions have occurred. The objective of the project Is to adapt Ozone Monitoring Instrument (OMI) operational algorithms to other satellite instruments and create consistent multi-satellite L2 and L3 nitrogen dioxide (NO2) columns and value-added L4 surface NO2 concentrations and NOx emissions data products, systematically accounting for instrumental differences. The instruments include Global Ozone Monitoring Experiment (GOME, 1996-2011), SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY, 2002-2012), OMI (2004-present), GOME-2 (2007-present), and TROPOspheric Monitoring Instrument (TROPOMI, 2018-present). The quality assured L2-L4 products will be made available to the scientific community via the NASA GES DISC website in Climate and Forecast (CF)-compliant Hierarchical Data Format (HDF5) and netCDF formats.
