GES DISC has introduced a new service to help users download data more efficiently. You may want to check it out to see if it improves your download speed. It also offers an option to generate Python code for downloading data. First, go to the dataset landing page: https://disc.gsfc.nasa.gov/dataset...

Thanks for sharing the code. I actually asked the "url: String containing the URL of the file to download". I assume you have downloaded many files. I just need an example of one file to get the idea where you get the data.

To better assist you, could you please let us know which specific files you encountered issues with, along with examples of file...

Dear User, Please share examples of the URLs that are returning error files, along with URLs that successfully return valid files, and the exact command you used to download the data (e.g., wget or curl). We’d also like to check whether this issue may be related to reprocessed granules that use a sl...

If you study the long-term change of aerosols, you may want to consider the monthly aerosol collection tavgM_2d_aer_Nx (M2TMNXAER). Adding to Allie's reply, which is good, the MERRA-2 FAQ may provide you additional information (https://gmao.gsfc.nasa.gov/gmao-products/merra-2/faq_merra-2/). You can ...
