Download of Aqua MODIS SST data

by ASDC - ingridgs » Fri Nov 25, 2022 11:34 am America/New_York

Dear Earthdata support team members,
I am trying to download MODIS SST data (for instance: "https://oceandata.sci.gsfc.nasa.gov/directdataaccess/Level-3 Mapped/Aqua-MODIS/2021/336/AQUA_MODIS.20211202.L3m.DAY.SST4.sst4.4km.nc") via a wget script under Linux. While I followed the steps to generate a .netrc file and also otherwise followed the instructions about how to download the data I am not able to retrieve the netCDF file with its full file size / it is not recognized as a netCDF file. That particular file is downloaded with a size of 18562 Bytes.
However, when I am using a browser (Mozilla Firefox) I can download the file without any problem.
While you might say, ok, then do it via the browser ... I wish to download the data beginning December 2021 until now, daily and monthly, Terra and Aqua, night and day SST ... hence the browser is certainly not an option. I would therefore be grateful if you could assist me in solving the riddle and also tell me how to download more than just one file in one command. Thank you.
Best Regards!

Hello,

I downloaded the file using following code without any problem:

Code: Select all

wget --load-cookies ~/.urs_cookies --save-cookies ~/.urs_cookies --auth-no-challenge=on https://oceandata.sci.gsfc.nasa.gov/ob/getfile/AQUA_MODIS.20211202.L3m.DAY.SST4.sst4.4km.nc
If you plan to do bulk downloading, you may want to follow the instructions here: https://oceancolor.gsfc.nasa.gov/data/download_methods/

Please try again and let us know if the problem still exists.
Guoqing
