OMI/Aura NO2 Tropospheric, Stratospheric & Total Columns MINDS Daily L2 Global Gridded 0.25 degree x 0.25 degree V1.1 (OMI_MINDS_NO2G) at GES DISC
atmosphere NASA GES_DISC Level 2G active
In plain English

What it measures. Daily maps of nitrogen dioxide, a common air pollutant, given as the total amount in a column of air and split into the lower-atmosphere and upper-atmosphere portions, on a fine 0.25-degree grid.

How it's made. Retrieved from the OMI instrument on the Aura satellite using algorithms designed to produce a consistent long-term record that can be carried across multiple satellites.

How & where you'd use it. Tracks air pollution and changes in nitrogen-oxide emissions over the past couple of decades, supporting air-quality and emissions 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.
