I’m new to using data from HYCOM and I’m trying to download data from the “GOFS 3.1: 41-layer HYCOM + NCODA Global 1/12° Analysis”. I need the eastward and northward sea velocity from a given bounding box for the period of 1 year. I have a shell script, however, when I tried using it with the OPENDAP access (selecting the variables I need on OPENDAP) I got archives with no data.
