Unable to download from NSIDC

timstevens1 commented 7 years ago

I wrote this script to download snow data from the NSIDC:

import modisSuite

username = ""
password = ""
product = "MOD10A2.006"
tiles = ["h20v02"]
start_date = "2011-01-01"
d = 20
folder = "../test_data"

doo = modisSuite.downloader(product, username, password, date=start_date, delta=d, tuiles=tiles, output=folder)
for x, y in doo.telechargerTout():
    print(x, y)

I then recieved this error:

/usr/bin/python2.7 /home/tim/Documents/Research/arctic-browning/scripts/snow.py

Has anyone experienced this issue before?

Hi, It can happen for different reasons

Servers are down
Bad username and password
applications (LP DAAC Data Pool and NSIDC_DATAPOOL_OPS) are not allowed in Earthdata configurations.
Any other problem with connection.

Try:

Go to https://urs.earthdata.nasa.gov/ and create a count if not created and login
In the section My applications approve the applications LP DAAC Data Pool and NSIDC_DATAPOOL_OPS
Try again.

Tell me if it works.

I shall

[x] Add these instruction in README.md file.
[ ] Add a bit of code in the authentication procedure so that it give better feedback then this.
[ ] Find a way to automatically approve the applications when trying to connect.
