Howdy all!
I've just released version 2.0 of the NetCDF Expansion Pack:
https://github.com/Intelligent-Data-Design-Inc/NEP
NEP extends NetCDF-4 with powerful new capabilities for scientific data
workflows:
Compression <https://github.com/Intelligent-Data-Design-Inc/NEP#compression>
Algorithm Speed vs DEFLATE Ratio vs DEFLATE Best For
LZ4 2–3× faster ~2.2× Real-time processing, HPC I/O
BZIP2 Slower ~6.7× Long-term archives, bandwidth-limited
Both are HDF5 filter plugins — drop-in with existing NetCDF-4 applications,
no code changes.
Multi-Format Readers
<https://github.com/Intelligent-Data-Design-Inc/NEP#multi-format-readers>
Format Domain API
NASA CDF Space physics (IMAP, MMS, Van Allen) nc_open() / nf90_open()
GeoTIFF Geospatial rasters, CF-1.8 CRS metadata nc_open() / nf90_open()
GRIB2 NWP model output (GFS, NAM, HRRR, wave) nc_open() / nf90_open()
FITS Astronomical images and tables (HST, JWST) nc_open() / nf90_open()
All readers use the standard NetCDF UDF system. Existing C and Fortran
programs require no code modification — an existing Fortran program that
calls nf90_open() and nf90_get_var() can read a FITS, CDF, GeoTIFF, or
GRIB2 file without changing a single line of code. NEP registers the format
handler at startup; the rest of the program stays identical.
Example Programs
<https://github.com/Intelligent-Data-Design-Inc/NEP#example-programs>
NEP includes over 26 C and Fortran example programs, organized by topic.
They are companion code for *The NetCDF Developer's Handbook: The
Authoritative Guide to Writing High-Performance Programs for Scientific
Data Management
