PPS TRMM Science Algorithm Toolkit

Please note: The TRMM mission ended in 2015. The documentation below is provided for reference and historical purposes only. Users seeking the current GPM Science Algorithm Input/Output Toolkit (TKIO) should visit our PPS Science Algorithm Toolkit (TKIO) web page. Additionally, some links referenced on this page may be obsolete and not function as expected.

To help the PPS Science Users develop the TRMM algorithms, PPS has provided the TRMM Science Algorithm Toolkit. The purpose of the toolkit is two-fold. First, the toolkit provides a library of commonly used routines, constants, and macros, and, secondly, it allows seamless integration of TRMM algorithms into the PPS environment.

In developing algorithms for PPS the science users must interact with HDF files for PPS standard products. The toolkit provides routines for reading and writing data to and from the HDF files; routines are provided for Level 1-3 products and for TRMM satellite data. Each of the routines in the toolkit is callable in either C or FORTRAN. The toolkit also includes routines for reading land/sea data and topographical data. The routines provided in the toolkit can be divided into the following categories:

  • File Access (e.g., open/close routines)
  • Data Access (e.g., read/write routines)
  • Metadata Access (e.g., reading and writing metadata elements)
  • Ancillary Data Access (e.g., land/sea or topographical data access)
  • Error Reporting Utilities.

PPS Toolkit for Previous Version 6 TRMM Products

 

PPS has provided the PPS Science Algorithm Toolkit to assist the science users. The purpose of the toolkit is two-fold. The toolkit provides a library of commonly used routines, constants, and macros. It also allows seamless integration of TRMM algorithms into the PPS/TSDIS environment.

The toolkit provides routines for reading and writing data to and from the HDF files; routines are provided for Level 1-3 products and for both satellite and GV. Each of the routines in the toolkit is callable in either C or FORTRAN. The toolkit also includes routines for reading land/sea data and topographical data.
