Originally created by NASA Goddard Space Flight Center, data provided to CARDAT by Luke Knibbs.
This is Satellite data OMI/Aura NO2 Cloud-Screened Total and Tropospheric Column L3 Global Gridded 0.25 degree x 0.25 degree V3 (OMNO2d).
For full information see https://disc.gsfc.nasa.gov/datasets/OMNO2d_003/summary
The Ozone Monitoring Instrument (OMI) aboard the Aura satellite produces daily global observations of NO2 tropospheric column abundance at a resolution of 13-24 km2(nadir) using a differential optical absorption spectroscopy (DOAS) algorithm (Levelt et al., 2006). We obtained the average tropospheric NO2 columns over Australia for each month from 2005-2016. We then produced estimates of ground-level NO2 by using the Weather Research and Forecasting model (WRF-Chem) to predict monthly surface-to-column ratios. This approach is a standard method to convert tropospheric column NO2 abundance (in molecules per cm2) to ground-level NO2 concentration (in ppb), and has been described extensively (Lamsal et al., 2008; Bechle et al., 2013).
Detailed information on satellite data retrieval and processing is given in the supplement to Knibbs et al. 2014 (pages S3–S9 https://cloudstor.aarnet.edu.au/plus/f/1718144803, DOI: 10.1016/j.envres.2014.09.011). This is the data used by Knibbs et al. 2014, with additional years downloaded. Knibbs et al. 2014 cited it as Aura OMI level-3 NO2 product via NASA Giovani interface http://gdata1.sci.gsfc.nasa.gov/daac-bin/G3/gui.cgi?instance_id=omi
