Hello,
I used the following code to download MODIS/AQUA L1A data from July 2023 to May 2024:
wget --user=[my account] --password=[my password] --auth-no-challenge https://oceandata.sci.gsfc.nasa.gov/getfile/A2024127062000.L1A_LAC.bz2
However, all data cannot be downloaded completely and usually breaks down around 10% of the download. My Internet is working.
How to solve this problem, is the network issue of ocean color still not fully fixed?
Thanks for your help.
