            HARP 1.22 Release Notes

HARP is a toolset for ingesting, processing and inter-comparing satellite or model data against correlative data. The toolset is composed of a set of command line tools, a C library of analysis functions, and import/export interfaces for Python, R, Matlab, and IDL. The main goal of HARP is to assist in the inter-comparison of data sets. By appropriatelty chaining calls to the HARP command line tools one can preprocess satellite, model, and/or correlative data such that two datasets that need to be compared end up having the same temporal/spatial grid, same data format/structure, and same physical unit.

The main functionalities of HARP are:

• ingestion of product data for:
  • ACE FTS L2
  • ADM-Aeolus L1b/L2a/L2b
  • Aura OMI/TES/MLS/HIRDLS L2 + OMI L3
  • CALIPSO (Lidar L2)
  • CLOUDNET classification L2
  • AERLINET
  • ECMF GRIB (includes CAMS global model data)
  • ENVISAT GOMOS/MIPAS/SCIAMACHY L1/L2
  • ERS GOME L1/L2
  • ESA CCI Aerosol/Cloud/GHG/Ozone
  • GEOMS FTIR/Lidar/MWR/Pandora/Sonde/UVVIS-DOAS data (NDACC/EVDC)
  • GOSAT FTS L1/L2
  • Metop GOME-2/IASI L1/L2
  • NPP Suomi (CrIS/OMPS/VIIRS) L2
  • ODIN OSIRIS/SMR L2
  • QA4ECV NO2/HCHO L2
  • Sentinel 5P L1/L2
  • TEMIS ozone fields
• import/export of data from/into HARP-specific data format The HARP data format standard is a convention on top of netCDF3/HDF4/HDF5
• advanced filtering of product data
• automatic unit conversion of quantities using udunits2
• automatic generation of quantities ('derived variables') based on available product data: you just say which quantity you want, and if HARP has an algorithm for it and the necessary inputs quantities are in the product, HARP will automatically do all calculations for you
• regridding in any dimension
• vertical smoothing of atmospheric profiles
• creating L3 grids
• built-in AFGL86 and USSTD76 climatology data
• C Library interface to all core functionality
• direct import/export interfaces for Python, R, Matlab, and IDL
• command line tools harpcheck, harpcollocate, harpconvert, harpdump, and harpmerge
• extensive documentation, including specification of algorithms used for the variable derivations.
