Please complete the form below to submit a request to run the Subsetter process. Note that some processes are restricted to registered users only. Click the 'Submit' button to submit your request.

Process Abstract: A Subsetting tool that allows the extraction of variable subsets from a range of datasets. The user can select a dataset, a single variable, time range and bounding box. The output format can also be selected (NetCDF or CSV) along with instructions on how to divide output files into sensible time chunks. The tool uses CDAT's CDMS (Climate Data Management System) libraries to interact with the datasets in the archives. The extraction jobs run on the batch processing servers and the user is e-mailed when the job has completed.

Instructions for the Subsetter process:  See User Guide
