  NOAA Unique CrIS/ATMS Processing System (NUCAPS) EDR Software Version 1.1 Release

14 December 2015

The University of Wisconsin-Madison SSEC is pleased to announce a new release of the NOAA/NESDIS/STAR NOAA Unique CrIS/ATMS Processing System (NUCAPS) Environmental Data Record (EDR) software for retrieval of atmospheric profiles of temperature, moisture and trace gasses as well as cloud-cleared radiances from input Suomi-NPP CrIS and ATMS Sensor Data Records (SDRs). 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).

NUCAPS development is led by Walter Wolf and Quanhau (Mark) Liu at the NOAA NESDIS Center for Satellite Applications and Research (STAR). This CSPP release was created in close collaboration with Chris Barnet, the NOAA government science lead for NUCAPS from 2003 to 2013, who is the developer of the NUCAPS science code, and the scientist most familiar with the algorithm. This CSPP release provides NUCAPS version 1.1, adapted and tested for operation in a real- time direct broadcast environment. The software 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 NUCAPS package is not included in this release.

What is new in NUCAPS Version 1.1

Updates to the Version 1.0 release include:
  • an option to aggregate NUCAPS-EDR and NUCAPS-CCR-AR files into overpass length files in post-processing ( option --aggregate ),
  • a reprocessing mode that allows for local repository of GFS data in GRIB1 or GRIB2 format (option --reproc=1/2 ),
  • support for 7 field-of-view CrIS files following the removal of FOV.6 on 18th August, 2015 ( option --fovs=7 ),
  • and the list of temperature, surface and water vapor sounding channels has been updated to properly reflect the instrument differences between AMSU and ATMS.
System requirements for the CSPP NUCAPS 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),
  • 4 GB of disk space (plus space for your own DB data and CSPP NUCAPS products).
The output products are two NetCDF files containing:
  • Environmental Data Record (EDR) vertical profiles of temperature, moisture and trace gasses (NUCAPS-EDR_v1r0_npp_*.nc files), and
  • Cloud-cleared radiances (NUCAPS-CCR-AR_v1r0_npp_*.nc files).
Manuscripts containing complete descriptions of the algorithm, inputs and outputs are included in this release.
