Re: Photosynthetically Active Radiation Data

MERRA-2 PAR products are in our Giovanni system, and that provides an opportunity to make a quick analysis for a particular region such as Door County. For Door County in particular, you would have to make a bounding box, or you could do the state of Wisconsin and just look at the values visually. I...

Re: Looking for data set AIRS AIRICRAD with gap filled at 6 microns

This suggestion is from one of our staff members familiar with AIRS data.

The SNDR12CHRP1 version 2 data collection may work. https://doi.org/10.5067/WIG2N5C20MRJ

This data collection "fills" in missing channels, though I don't know if it would fill in that much of a gap.
