New HDF5 High Level functions for region references, hyperslabs, and bit-fields

We are pleased to announce a new set of C and Fortran convenience functions designed to facilitate access to remote sensing data in HDF5. The data will be gathered by a new generation of low earth orbiting satellites that monitor environmental conditions for long-range weather and climate forecasts. (Refer to the NPOESS project for details.)

The source code, installation instructions and a draft of the User's Guide are available from:

   https://gamma.hdfgroup.org/ftp/pub/outgoing/NPOESS/source/

The Reference Manual can be found at:

   https://support.hdfgroup.org/projects/npoess/HL_NPOESS/doc/index.html

While these functions were created to facilitate access to NPOESS data, some of them may be useful to anyone working with HDF5 region references, hyperslab selections, or bit-fields. For a quick introduction to region references and hyperslab selections see the HDF5 Tutorial:

   https://support.hdfgroup.org/HDF5/Tutor/advanced.html

We are looking forward to receiving your comments on this new set of routines.
