The MODLST_SPA functions in two modes: Standalone, or as an IPOPP plug-in.
The LST algorithm was provided to the DRL by the MODIS Land Rapid Response Team. This version of the MODLST_SPA addresses stability and portability issues across multiple platforms, and includes enhancements to input checking and error handling.
The DRL has packaged this Science Processing Algorithm (SPA) with Version 1 of the algorithm wrapper. The algorithm wrapper provides a common command and execution interface to encapsulate multi-discipline, multi-mission SPAs. The wrapper also provides a structured, standardized technique for packaging new or updated algorithms with minimal effort.
This Land Surface Temperature (LST) algorithm uses brightness temperatures in MODIS bands 31 and 32 to produce day and night LST products at 1-km spatial resolutions in swath format. It uses MODIS Level 1B 1-km and geolocation HDF files and outputs LST in HDF.
Download the MODLST_4.14_SPA_1.0.tar.gz and MODLST_4.14_SPA_1.0_testdata.tar.gz (optional) files into the same directory.
Decompress and un-archive the MODLST_4.14_SPA_1.0.tar.gz and MODLST_4.14_SPA_1.0_testdata.tar.gz (optional) files:
$ tar -xzf MODLST_4.14_SPA_1.0.tar.gz
$ tar -xzf MODLST_4.14_SPA_1.0_testdata.tar.gz
See the PDF document included within the software package for more details.
In order to run the package using your own input data, you can either use the run scripts within the wrapper directory, or modify the test script within the testscripts directory. See the PDF document included within the software package for more details.
