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

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.

Question: PIC Algorithms

Re: PIC Algorithms

The PIC algorithms are based on the light scattering properties of coccolithophorids, primarily Emiliania huxleyi. Because of their larger size and generally lower population density in the water column, calcareous zooplankton are unlikely to significantly influence the ocean optical characteristics...

The latter is also reconciled with PPS (the jsimpson host). There is nothing missing in CMR for IMERGHHL. Users should be careful in using CMR API qu...
