Follow instructions in order to download data:

Make an EarthData Account

  1. Create an Earthdata account at
  2. Link GES Disk with your account. Follow instructions at this link: https://disc.gsfc.nasa.gov/earthdata-login
  3. Create a .netrc file, as this will contain your username and password. 
    > cd ~
> touch .netrc
> echo "machine urs.earthdata.nasa.gov login uid_goes_here password password_goes_here" > .netrc
> chmod 0600 .netrc
  4. Create a cookie file that will be used to persist sessions across individual cURL/Wget calls, making it more efficient.

Resources used: https://wiki.earthdata.nasa.gov/display/EL/How+To+Access+Data+With+cURL+And+Wget https://disc.gsfc.nasa.gov/data-access#mac_linux_wget

Run in terminal

wget --load-cookies ~/.urs_cookies --save-cookies ~/.urs_cookies --keep-session-cookies -r -c -nH -nd -np -A nc4 --content-disposition -i myfile.dat

The command above takes in urls from myfile.dat and downloads all nc4 files inside each of them. Note that myfile.dat is a list of urls provided.
