tdftohdf - Export Terascan datasets to HDF/netCDF format

SYNOPSIS

tdftohdf  [ parameter=value ... ]  [ inputfile outputfile ]
tdftohdf  [ parameter=value ... ]  [ inputfile ... directory ]

Parameter is: include_vars.

DESCRIPTION

tdftohdf exports TeraScan dataset variables to HDF/netCDF-formatted datasets. HDF (Hierarchical Data Format) was developed by the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign. netCDF (network Common Data Format) was developed by Unidata Programs at the University Corporation for Atmospheric Research. Both of these dataset formats are public domain analogs to the TeraScan dataset format (see datasets). Each has independently produced a library of functions, and in some cases utility programs, to read, write, and manipulate multi-dimension, multi-type, multi-variable datasets. HDF has several interfaces built around 8- or 24-bit images, scientific data, tabulated data, etc. The translation performed by tdftohdf exports TeraScan datasets to the Scientific Data Set (SDS) format of HDF. As of version 3.3r3 of HDF, the HDF library views netCDF and SDS datasets synonymously. Thus exported TeraScan datasets appear as both HDF SDS datasets and netCDF datasets, with some caveats regarding backward compatibility (see documentation listed under NOTES).

Input datasets can be any valid TeraScan dataset. One output dataset is created for each input dataset. The input and output dataset variables have the same data representation (e.g., short, int). Variable units, valid max, valid min, bad value, scale, and offset are all exported to the output dataset. Also exported are dimension names and global and variable attributes.

Variables with units of std_date and std_time are converted to integer yymmdd values and float (or integer) hhmmss[.ss] values, respectively (see dates, timestr, formats).

PARAMETERS

include_vars

Specifies the list of variables to export. If the list is preceded by a minus sign, all variables except those listed will be exported. Wildcards * and ? are allowed. The default is to export all variables.
