netCDF data download

Hi there,

I'm trying to get weather data values for temperature (2-meter), relative humidity (2m), wind speed (10m) and precipitation in specific time period. As far as I learned I can get data in CDF format. I looked at code example (C#) in GES DISC "How-Tos" (https://wiki.earthdata.nasa.gov/pages/v ... d=76519934) section, but I can't figure out how to construct resource data url. Any help?

Best regards,

Mursel

Hello,

First may we suggest you view the MERRA-2 file specific to find the data collection that contains the interested variable:
https://gmao.gsfc.nasa.gov/pubs/docs/Bosilovich785.pdf

Then, follow the data how-to in the links below:

Thanks a lot for Your quick reply.

Is there a way to generate data for an specific country (country shape), like in Giovanni, but using scripts?

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.

Thank you both. I succeeded to create valid http web request against GES DISC service and get valid response using .NET classes HttpWebRequest and HttpWebResponse.
