Gridded OMI NO2
This dataset contains daily gridded DOMINO NO2 data, zipped into monthly files. These data were generated from Level-2 satellite data (on swaths) and gridded to a 12 km x 12 km horizontal resolution over the Continental U.S. using the Wisconsin Horizontal Interpolation Program for Satellites (WHIPS) for ease of comparison with photochemical grid model output. (If your model data are on a different grid, you can use WHIPS to regrid Level-2 data to your custom grid.) Within each set of monthly files, there is a README file for information on how the data were processed, as well as a WHIPS runscript.
Gridded OMI HCHO will be available soon, as well as scaled surface NO2 and HCHO.
These data may be sampled and/or averaged over time using a Matlab script. Download instructions for running the script, the script itself, and an example (optional) input file for extracting data from user-defined latitude and longitude points.
When publishing results using these data, please include a citation for their processing:
