Community Satellite Processing Package

  Microwave Integrated Retrieval System (MIRS) Software Version 1.0 Release

20 March 2014

The University of Wisconsin-Madison SSEC is pleased to announce the release of the NOAA/NESDIS/STAR Microwave Integrated Retrieval System (MIRS) for retrieval of atmospheric profile and surface parameters from ATMS, AMSU-A, and MHS microwave sensor data. This package is in support of Direct Broadcast users, and is sponsored by the Community Satellite Processing Package (CSPP) project funded by the NOAA/NASA Joint Polar Satellite System (JPSS). MIRS development is led by Sid-Ahmed Boukabara at the NOAA NESDIS Center for Satellite Applications and Research (STAR). This release provides MIRS version 9.2 adapted and tested for operation in a real-time direct broadcast environment. For more information on MIRS, please visit

The CSPP_MIRS v1.0 software package contains binary executable files and supporting static data files, as well as input and output files for verification of a successful installation. Source code for the MIRS package is not included in this release. Source code can be provided upon receipt of a signed NOAA license agreement available from

System requirements for the CSPP_MIRS v1.0 software are as follows:
  • Intel or AMD CPU with 64-bit instruction support,
  • 1 GB RAM
  • CentOS-6 64-bit Linux (or other compatible 64-bit Linux distribution),
  • 1 GB of disk space (plus space for your own DB data and CSPP_MIRS products).
Supported satellites, sensors, and data include:
  • Suomi NPP ATMS SDR (from CSPP)
  • NOAA 18 and 19 AMSU-A and MHS Level 1B (from AAPP)
  • Metop-A and Metop-B AMSU-A and MHS Level 1B (from AAPP)
Official Validated Products created by MIRS include:
  • Temperature profile over open water ocean
  • Humidity profile over open water ocean
  • Humidity Profile over non-coastal Land
  • Total Precipitable Water (TPW) over open water ocean
  • Total Precipitable Water over non-coastal land
  • Land surface temperature
  • Surface Emissivity over land and snow
  • Surface Type Classification
  • Snow Water Equivalent (SWE)
  • Sea Ice Concentration (SIC)
  • Snow Cover Extent (SCE)
  • Vertically-Integrated Non-precipitating Cloud Liquid Water (CLW) over open water ocean
  • Vertically-Integrated Graupel Water Path (IWP)
  • Vertically-Integrated Rain Water Path (RWP)
  • Rainfall Rate (RR) over open water ocean and non-coastal, non-snow-covered land surface types
Experimental Products (not fully validated) created by MIRS include:
  • Cloud Liquid Water Profile (CLWP) over ocean
  • Surface Temperature (skin) extended to snow-covered land surface type
  • Surface Temperature (skin) extended to open ocean water
  • Effective grain size of snow (over snow-covered land surface)
  • Multi-Year (MY) Type Sea Ice Concentration
  • First-Year (FY) Type Sea Ice Concentration


Please note that in the Microwave Integrated Retrieval System (MIRS) Interface Control Document (ICD) version dated November 2012, specifically Table 24 on page 100, the HDF-EOS swath data record descriptions are not currently used, and should be ignored. For sounding product descriptions, including the correct variable units, please refer to Table 26 (MIRS SND file contents). In addition please note that in the output SND netCDF file itself, the metadata physical units description of hydrometeorological profile variables Pclw, Prain, Pgraupel, Pice, and Psnow are incorrect. The correct units are kg/m**2, or equivalently, mm.
