Tips for Downloading Data

The IRI Data Library is an OPenDAP Server. Therefore various languages and environments can be used to access the SubX data via OPenDAP. Once an OPenDAP connection has been established, the data are stored as netCDF. Sample programs to download data are available in Matlab, Python, NCL, and GrADS on github.
