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/.NCDC/.GCPS/.MONTHLY/.STATION/T/%28Jan%201901%29%28Dec%201990%29RANGE/a:/.lon/:a:/.lat/:a:/.mean/.prcp/T/3.0/0.0/boxAverage/T/12/splitstreamgrid%5BT2%5D0.75/percentileover/%7Bdry/0.33333/normal/0.66667/wet%7Dclassify/SOURCES/.KAPLAN/.Indices/.NINO3/.avOS/T/%28Jan%201901%29%28Dec%201990%29RANGE/T/3/0.0/boxAverage%5BT%5D0.0/percentileover/%7BLaNina/0.2/Neutral/0.8/ElNino%7Dclassify/1/masklt/T/12/splitstreamgrid/mul%5BT2%5Daverage/tercileclassesscale/c:/100/%28percent%29:c/mul/DATA/0/100/RANGE/long_name/%28Probability%29def/:a/IWMO+integral/2+index/%5BIWMO+%5Drmsover/1+index/4+index/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.
