Authentication failure - using wget via HPC based Linux

by pmamegbor » Wed Apr 19, 2023 2:05 pm America/New_York

Hi

I am trying to download M2I3NVAER .nc data from GES DISC, using wget and following the instructions here.

Due to the size of the data over 1TB I am downloading the data to HPC platform. I have the correct login details pr credentials. However, I get a username/password failure with the following message

Reusing existing connection to urs.earthdata.nasa.gov:443.
HTTP request sent, awaiting response... 401 Unauthorized

Username/Password Authentication Failed.

This is the GES DISC User Service. First please follow the data access instruction in the link below,
https://disc.gsfc.nasa.gov/data-access Make sure you have a wget of 1.18 or greater.

Hi,
I did follow the instruction on https://disc.gsfc.nasa.gov/data-access

I have used the instruction to access other datasets e.g. SO2, organic carbon, etc. This is the first time I am doing so via an HPC platform.

The wget information shows version 1.19 (GNU Wget 1.19.5 built on linux-gnu)

This is the command I used

cd $/scratch/xxxx/
touch .netrc
echo "machine urs.earthdata.nasa.gov login xxxx password xxxx" >> .netrc
chmod 0600 .netrc
touch .urs_cookies.

wget --load-cookies ~/.urs_cookies --save-cookies ~/.urs_cookies --auth-no-challenge=on --keep-session-cookies --content-disposition -i PM_Data_2020-21.txt (using a subset of the M2I3NVAER data, subsetted by the years in the file name and variables for computing PM10)

Please remove '--auth-no-challenge=on' option from wget

Also .netrc has to be in home directory -- looks like you created it in the directory
other than home

Sorry, for the late reply. I got caught up in other duties but unfortunately, it did not work. Also, I don't think the problem is not using the home directory. I have accessed and downloaded other GES DISC data e.g. NO2 on folders other than the home directory. I downloaded the other data to my external hard drive following the same instructions here: https://disc.gsfc.nasa.gov/data-access. I am using the HPC platform due to the size of the M2I3NVAER .nc data

I tried downloading just a day's data to my external hard drive. It seems to be working but I get
