Accessing data using your copy of NCL*

DODS allows one to give a application a url and have it directly download data. To read this data into NCL use
addfile("http://iridl.ldeo.columbia.edu/SOURCES/.NOAA/.NCEP-NCAR/.CDAS-1/.MONTHLY/.Intrinsic/.PressureLevel/.temp/P/%28850%29%28200%29RANGE/Y/%2825S%29%2825N%29RANGE/a:/T/%28Dec%201981%29last/RANGE/:a:/T/%28Jan%201981%29%28Dec%202010%29RANGE/yearly-climatology/sub/:a%5BY%5Daverage/std_anomaly_colors/T+differences/%5BX+P+T+%5Dminover/dods","r")
If you have questions, comments, or problems please use the help@iri link. This page will evolve as we learn more about how NCL handles data downloads, and your help pointing out problems is much appreciated.


*DODS (a.k.a. OpenDAP) is not necessarily installed in NCL and if OpenDAP is not installed, giving NCL a URL instead of a local file name will result in a file-not-found error. In that case, you can use addfile after you download the netcdf file.
