Tools

The src/Makefile builds the following command-line executables:

  • day2doy
  • doy2day
  • events
  • jsec2time
  • map
  • perturbation
  • prof
  • response
  • time2jsec
  • tropo
  • variance

What They Are Used For

The tools cover a small set of common workflows around GPS radio occultation data:

  • date and time conversion utilities
  • event extraction and tabular summaries
  • map and profile export
  • perturbation analysis
  • tropopause diagnostics
  • response and variance calculations

Several executables share infrastructure from:

  • libgps.c and libgps.h: project-specific I/O and analysis helpers
  • jurassic.c and jurassic.h: vendored code from the external JURASSIC radiative transfer model

Build And Test Entry Points

Most users will interact with the tools through the main build workflow:

cd src
make
make check
