Copyright (C) 2015 S[&]T, The Netherlands HARP 0.1 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 and a library of analysis functions. 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 and correlative data such that the two datasets that need to be compared end up having the same temporal/spatial grid, same data format/structure, and same physical unit. This version of HARP is a beta release to allow the community to get familiar with the software and provide feedback. HARP still lacks various components (see below), but these are planned to be added during the first half of 2016. The current version of HARP contains: - ingestion of product data for: - Sentinel 5P L1/L2 - Ozone CCI L2 - NDACC FTIR/Lidar/MWR/UVVIS-DOAS data (GEOMS format) - GOME-2 L2 - IASI L2 - OMI L2/L3 - TES/MLS/HIRDLS L2 - GOSAT FTS L1/L2 - MIPAS L2 - import/export of data from/into HARP-specific data format The HARP data format standard is a convention on top of netCDF/HDF4/HDF5 similar to netCDF-CF (and can be used in conjunction with netCDF-CF). - 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 - built-in AFGL86 and USSTD76 climatology data - C Library interface to all core functionality - command line tools harpconvert, harpfilter, harpdump, harpcheck - harpcollocate command line tool providing collocation of two datasets at individual measurement level Note that HARP is meant as a successor to the BEAT-II interface of the ESA Atmospheric Toolbox, which means that BEAT-II will at some point become deprecated and will no longer receive updates. Restrictions ============ Note that this version of HARP is not yet feature complete. The following items are planned to be added in the coming year: - Windows build support + binary packages for Windows 32bit/64bit - ingestion of product data for: - NPP Suomi (CrIS/ATMS/OMPS/VIIRS) L2 - Cloud CCI - GHG CCI - Aerosol CCI - GOMOS L1/L2 - MIPAS L1 - SCIAMACHY L1/L2 - GOME L1/L2 - GOME-2 L1 - IASI L1 - OSIRIS L2 - SMR L2 - ACE-FTS - CAMS (Copernicus Atmospheric Monitoring Service) - ADM/Aeolus - direct ingestion/import/export interfaces for: - Python - MATLAB - IDL - harpprofile command line tool to modify atmospheric profile data: - vertical regridding - vertical smoothing using averaging kernels (and a-priori profiles) Installation ============ Installation instructions can be found in the HARP documentation or the INSTALL file. Download ======== The HARP software is distributed as part of the ESA Atmospheric Toolbox and can be downloaded from the BEAT website: http://stcorp.nl/beat If you encounter any issues with the toolkit or if you would like to see certain functionality added, let us know at: harp@stcorp.nl HARP Developers S[&]T, The Netherlands
