Introduction
This guide describes how to retrieve data from the TRMM mission (http://trmm.gsfc.nasa.gov/data_dir/data.html
) and import them into Delft-Fews.
The attached scripts are examples only and should be customized by the user. The scripts are supplied without ANY warrenty.
Data type and location
The scrips use the 3B42RT product (merged IR and Microwave) but may be adapted to use the other products. The data is located at: trmmopen.gsfc.nasa.gov/pub/merged/mergeIRMicro . Please visit the original site for details of the data (http://trmm.gsfc.nasa.gov/data_dir/data.html).
Scripts
- gettrmm.pl -> gets the last n files from the ftp site, and call the trmmconv.pl converted to convert to arcview ascii that can be imported into Delft-Fews (see http://public.deltares.nl/display/FEWSDOC/ArcInfoAscii)
- trmmconv.pl -> converts the files
How to get it working
- Download the attached scripts GetTRMM.zip and unzip
- Edit gettrmm.pl, insert your e-mail address and set the number of most recent files to download
- Run gettrmm.pl -> you should get the original data (in rawdata) and the converted data (in fewsimport). These directories can be configured.
An example configuration of the import module (ImportTRMM 1.00 default.xml) plus id mapping (IdImportTRMM 1.00 default.xml) is also attached to this page.
