Accessing data using your copy of GrADS*

This dataset has 5 dimensions while GRaDS can handle 4 (longitude latitude height time).
You can restrict 1 dimensions to one point each here Data Selection
or use the XDF features in GrADs to remap the dimensions (see GrADS documentation).

This dataset has S units of months since 1960-01-01 (360) for S (Forecast Start Time)

DODS allows one to give a application a url and have it directly download data. To read this data into GrADS use
xdfopen
where the first line of the description file looks like
DSET http://iridl.ldeo.columbia.edu/SOURCES/.IRI/.Analyses/.ICPAC/.Models/.Montreal/.CMC2-CanCM4/.FORECAST/.MONTHLY/orig+.tmax/dods
If you have questions, comments, or problems please use the help@iri link. This page will evolve as we learn more about how GrADS handles data downloads, and your help pointing out problems is much appreciated.


*On GrADS startup, the config line should read Config: ... DODS-enabled ..., otherwise DODS (a.k.a. OpenDAP) is not installed and giving GrADS a URL instead of a local file name will result in a file-not-found error. In that case, you can use xdfopen after you download the netcdf file.
