Re: aerosol data
I will check with my colleagues. To begin, I recommend this ARSET training set of videos (from a class), particularly part 3.

Re: aerosol data
Hello, Here is more information in response to your question. "I would like to suggest extracting PM2.5 from the daily AOD, and then calculate the monthly mean PM2.5. As such, the monthly PM2.5 value is more precise. When you convert AOD to PM2.5, you might need to consider the factors such as ...

- 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.

Re: aerosol data
Hello, Could you please point us to, or describe, which specific PM2.5 and PM10 data you used or intend to use? This will assist us in answering your question. Monthly mean AOD data from MODIS and Sentinel-5P (TROPOMI) is usually calculated from daily mean data with caveats, such as only daytime dat...

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...

Re: Missing files in GPM IMERG data
We have examined what you reported, and we do not see differences between the cumulus-published CMR inventory, and the inventory in s4pa for IMERGHHL. 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...
