Hello,

My colleague who would be the best to address this question is out of the office for a few more days. I have sent your message to him and I will post his reply after he has considered it.

OK, then we do not have a data product at the GES DISC that will work for you, and you can continue to examine the POWER data products.

Hello, Can you use Photosynthetically Available (or Active) Radiation (PAR)? The PAR spectral range is 400-700 nanometers. You can examine the PAR data products available in Giovanni at the link below. Some PAR products are only available for ocean regions, others are available over both land and oc...

Hello, It appears to me that you have two data ordering methods combined together. Giovanni does not provide downloaded files as a .tar file; and it does not have an order number. So I believe that you created an order with the OBPG data system. Giovanni does provide output as .nc files. CSV format ...

28 new Famine Early Warning Systems Network Land Data Assimilation System (FLDAS) data variables, based on Climate Hazards Group IR Precipitation with Station Preliminary (CHIRPS-PRELIM) 6-hr rainfall data, have been added to the Giovanni system, https://giovanni.gsfc.nasa.gov/.

The Goddard Earth Sciences Data and Information Services Center (GES DISC) and Jet Propulsion Laboratory Sounder Science Investigator-led Processing Systems (JPL Sounder SIPS) announce the release of Level 2 version 2 products from the AIRS (Atmospheric Infrared Sounder) and Advanced Microwave Sound...

Thank you for your interest in our data and services. When you download comma-separated value (CSV) files, you will find a line like this: Fill Value (mean_OMAERUVd_003_FinalAerosolOpticalDepth500):, -1.267651e+30 that appears near the beginning of the file, before the data values for the variable. ...

We will examine your question and try to determine a solution. Please stand by.

I am not familiar with the data variables in the MYD04_L2 data product. For your second question, MERRA-2 has a Black Carbon data variable and several dust aerosol data variables. OMI and TROPOMI have aerosol absorption variables for absorbing aerosols. Giovanni can provide a quick indicator even if...

Hello, Here is a partial answer, with links to resources that can provide more information. First of all, it would be helpful to provide more information on how you wish to use the data. We would like encourage you to read MERRA-2 File Specification ( https://gmao.gsfc.nasa.gov/pubs/docs/Bosilovich7...
