Utility Software

  • Software for interpolating profiles and mapping of Jacobians from the fast RT layering to NWP vertical coordinates (TL/AD/Gradient) is now part of RTTOV-9. A stand-alone version of the software is available at:
    http://exp-studies.tor.ec.gc.ca/e/paper_data/tstintavg_e.html
  • Profile_Utility webpage containing Fortran95 code and documentation to perform units conversions and level-to-layer conversions on atmospheric quantities (Forward models only).
