Hello. What temporal resolution are you seeking? There are a variety of data products that could be used, ranging from monthly averages to hourly values.

Stanislaus, Hello. The Goddard Earth Sciences Data and Information Services Center (GES DISC) has methane data from the Atmospheric Infrared Sounder (AIRS). Provided below are links to an AIRS methane data product search, and also to the AIRS methane data in the Giovanni data visualization system. W...

Hello, This question would be better handled by our technical/engineering staff. Please send your question to the GES DISC Help Desk. The link below provides a description of what information to include so that our staff can provide assistance to you as effectively as possible. The Help Desk email a...

Hello, GLDAS does not have any 1 km resolution precipitation data products. The best available spatial resolution is 0.25 deg. FLDAS has monthly 0.1 degree data, and rainfall flux is one of the variables available at that resolution. FLDAS monthly data set landing page: https://disc.gsfc.nasa.gov/da...

Here is the answer from a GES DISC staff scientist. In regard to your question on the soil moisture unit conversion, please go to https://ldas.gsfc.nasa.gov/faq/ldas and click on “Q. How can I obtain volumetric soil moisture [m^3 m-3] from the LDAS data?”. For the GLDAS soil porosity data, please g...

The GES DISC Help Desk recently received this question from a user, and it was answered by a GES DISC staff scientist. It is provided here for information content. I have a question regarding the conversion of the soil moisture content from kg m-2 (or mm) to volumetric soil moisture. Therefore, I'l...

Here is the answer, a collaboration between our SME and a GES DISC staff scientist. 1. GLDAS total runoff is the sum of subsurface runoff “Qsb_acc” and surface runoff “Qs_acc”. 2. Since the units of “kg m-2” as 3-hour accumulation is correct, there is no near term plan to change the units in the Ne...

The GES DISC Help Desk recently received this question from a user, and it was answered by a Subject Matter Expert. It is provided here for information content. I have a question regarding the runoff data from the GLDAS dataset and the way I should aggregate it within a hydrologic catchment. I have...

This was actually a question from our testing phase. Did you want additional information about the IR channels of AIRS?

The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) has recently published a Data-in-Action article entitled "Atmospheric Infrared Sounder (AIRS) surface temperature data show unusual Antarctic high temperatures in February" From the Introduction: In early Febru...
