Webinar announcement: A Clearer View of the Haze – Using NASA GES DISC Data Tools to Examine the June 2020 Sahara Dust Event Join us as we explore how GES DISC tools and data products can augment ongoing vital research on the dynamics of dust transport in Earth’s atmosphere. We will investigate the ...

Hello, Regarding your parameters: air temperature (2m) -- use AIRS daily data, you can specify the pressure level(s) or use the "Air temperature at surface" data product; relative humidity (2m) -- use AIRS daily data, you can specify the pressure level(s); precipitation in last 24h -- use ...

Dear Mursel, This How-To Document may be of use to you. I do not think you can subset with country/state shapefiles with this method, but it does allow definition of a region with lat/lon coordinates. https://disc.gsfc.nasa.gov/information/howto?keywords=API&title=How%20to%20Use%20the%20Web%20Se...

From the Precipitation Processing System (PPS) at Goddard Space Flight Center: "Dear Science User, The GPM spacecraft experienced an anomaly that caused an interruption of all science instrument data beginning on 8/19/2020 around 12:00 UT. GMI instrument data restarted collection on 8/26/2020 a...

Regarding GPM: On August 19, 2020 at approximately 11 UTC, the GPM Mission Operations Center (MOC) stopped receiving data from the satellite. While the satellite and the instruments are healthy, the Flight Operations Team (FOT) is working to safely reestablish nominal operations. Return to data coll...

Hello, What TOMS variable(s) are you using? The MERRA-2 dataset at the GES DISC has surface albedo data. We also have data from subsequent missions to TOMS -- OMI, OMPS, and TROPOMI, which may have data variables similar to what you are using with TOMS. And CERES data has other Earth radiation data ...

Hello, This is a temporary problem that the Giovanni development team is addressing, and it will be fixed shortly. As a work-around, you can plot a regular map of the same region that is used for the Hovmoller plot using the same legend (color palette), download the image, and use an image editing t...

Michael,

Hello - our staff members with Mac experience are taking a look at your question today. We will reply back if we have any solutions (and we'll also reply if we can't find a solution).

The negative SO2 values are artifacts of the retrieval process. They are usually associated with retrievals over highly reflective surfaces. The OMSO2.003 ReadMe has more detail than is contained in the OMSO2e ReadMe. https://aura.gesdisc.eosdis.nasa.gov/data/Aura_OMI_Level2/OMSO2.003/doc/README.OMS...

The variables 'PixelCornerLatitudes' and 'PixelCornerLongitudes' contain the coordinates of the corners of each pixel. The corner locations fall on either side of the pixel centers which are defined in the geolocation variables 'Longitude' and 'Latitude' which have dimensions nTimes and nXtrack . Ex...
