Process Title:
Subsetter
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.

Variable Variable The variable that you wish to subset. string item - - - True
StartDateTime Start Date Time The first date/time for which you wish to extract data. datetime item - - - True
EndDateTime End Date Time The last date/time for which you wish to extract data. datetime item - - - True
FirstLevel First Vertical Level The first vertical level for which you wish you extract data. You can specify a range between this value and that specified in the Last Level input. float item - - - True
LastLevel Last Vertical Level The last vertical level for which you wish you extract data. You can specify a range between the value specified in the First Level input and this value. float item - - - True
BoundingBox Bounding Box The spatial bounding box that you would like to extract data for. bbox item - - - True
OutputFormat Output Format The file format required for your output data. string item - nc

csv
- False
SplitOutputFilesIntoTimeChunks Split Output Files Into Time Chunks This instructs the process to split the output files into chunks of a fixed and constant duration. If the default value (AUTOMATIC) is selected then the process will try to determine a sensible chunking of the outputs based on the volume of the extraction. string item - AUTOMATIC
