Thank you. I will inquire to the MERRA-2 group to see if they can assist. Using Giovanni, you can make a six-month average simply by making the Begin Date January and the End Date June, when using monthly data. This will average the data over the entire period. Please do me a favor. Send your attach...

These are interesting images. Is the source of the 77% number a citation of a reduction in shipping traffic? Note that MERRA-2 is a model, not actual observational data. Determining how the algorithm generates the values of the MERRA-2 variable would require more effort. I can ask our MERRA-2 expert...

For further information, we suggest contacting Dr. Larrabee Strow at the University of Maryland - Baltimore County (UMBC).

Shaun, Thanks for your question. At this time do not have the capability to create a customized product such as you describe. Cloud computing may make such an operation easier and faster, but the data is not currently in the cloud environment. A short examination of the question indicated that the b...

Leon, Thanks for asking. The GES DISC has a couple of SO2 data products that might be examined. For today we did not have our SMEs for these data on alert, but they could be contacted. The OMI SO2 data product is more suited for large SO2 emissions, such as from volcanoes, but could be examined. TRO...

On Friday, October 2, this Earthdata Forum thread will be hosting a Forum Active Discussion (FAD) about the Webinar which was presented last week. The Webinar can be viewed on YouTube at this link: https://www.youtube.com/watch?v=CwMOF4FzULE If you have questions about the tools described, or about ...

Thanks for your comment. The GES DISC archives data from the Atmospheric Infrared Sounder (AIRS) on Aqua.

Here is the pertinent information from our NLDAS/GLDAS support staff: "The entire GLDAS-1 collection from January 1979 through March 2020 has been removed from the GES DISC system on June 30, 2020. With the upgraded Land Surface Models (LSMs) and updated forcing data sets, the GLDAS-2.1 product...
