The software operates in the Unix environment on IBM, SGI, Sun and HP workstations. Documentation is included with the software, describing how to install the IAPP, the design structure, and how each module operates. Below is a short description of the IAPP contents, licensing issues, and how to receive the package. The output file is in NetCDF format.
Detailed information is provided in the documentation.
Surface data in the WMO Metar format is used, if available, to improve surface condition definition. Numerical model output can be used as a first guess field for the atmosphere and surface. Any model can easily be adapted to fit in the IAPP retrieval scheme. Clearly written documentation makes this task relatively easy. Alternatively, a regression of raob radiance comparisons can be used to provide a first guess.
