Microwave Integrated Retrieval System (MIRS) Patch Release

Post by kathys »

CSPP Software Release: Microwave Integrated Retrieval System (MIRS) Patch Version 2.2.1

The Community Satellite Processing Package (CSPP) project is releasing a Patch for the NOAA/NESDIS/STAR Microwave Integrated Retrieval System (MIRS) Version 2.2 software for retrieval of atmospheric profile and surface parameters from direct broadcast microwave AMSU-A/MHS Level 1B and ATMS SDR data files.

What is new in CSPP MIRS Patched Version 2.2.1?

• Fixed bug resulting in malformed output file names for MetOp-A/B and NOAA-19 (incorrect day of month).
• Fixed bug in the snowfall rate (SFR) retrieval for AMSUA/MHS instruments onboard NOAA-18, NOAA-19, MetOp-A and MetOp-B.
• Switched to using HTTPS from HTTP protocol in ancillary data downloads.
• Verified retrievals using the new GFS FV3 forecast model file inputs which will become operational by mid-2019.

Please Note: The NOAA-18 MHS instrument began experiencing problems on 20 October 2018 and is not supported by the CSPP_MIRS software after this event.


Installing the CSPP MIRS Version 2.2.1 Patch

Users can either download and install a fresh tarball that includes the patch, or apply the patch over an existing installation.

1). New CSPP MIRS V2.2.1 installation

To install a stand alone CSPP MIRS V2.2.1 tarball, follow the instructions in the CSPP MIRS V2.2.1 Installation guide which can be found on the CSPP download site:

http://cimss.ssec.wisc.edu/cspp/download


2). Patch an Existing Version of CSPP MIRS V2.2

To patch an existing version of CSPP MIRS V2.2, follow the instructions below.

a). Download the CSPP MIRS Version 2.2.1 Patch (3.2 MB) (for example in ${HOME}):

cd ${HOME}
wget ftp://ftp.ssec.wisc.edu/pub/CSPP/mirs_v ... 2.1.tar.gz

b). Now apply the patch on top of your current MIRS Version 2.2 installation (for example in ${HOME}):

export $CSPP_MIRS_HOME=${HOME}/CSPP_MIRS_2_2

cd $CSPP_MIRS_HOME
tar xf ../CSPP_MIRS_PATCH_V2.2.1.tar.gz

c). Confirm a successfully patched installation by checking for Version number 2.2.1 in the $CSPP_MIRS_HOME/version.txt file.

cat $CSPP_MIRS_HOME/version.txt


The MIRS Team at NOAA is led by Quanhua (Mark) Liu and Chris Grassotti at the NESDIS Center for Satellite Applications and Research (STAR). The Version 2.2.1 release provides MIRS version 11.3 adapted and tested for operation in a real-time direct broadcast environment.

Supported satellites, sensors, and data include:

* NOAA-20 and Suomi NPP ATMS SDR (from CSPP or CLASS)
* NOAA 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), based on the SWE
* Vertically-Integrated Non-precipitating Cloud Liquid Water (CLW) over open water ocean
* Vertically-Integrated Ice 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
* Effective grain size of snow (over snow-covered land surface)**
* Multi-Year (MY) Type Sea Ice Concentration**
* First-Year (FY) Type Sea Ice Concentration**
* Snow fall rate (SFR)
**Note that FY and MY Sea Ice Concentration, as well as Snow Grain Size are not officially operational, but preliminary products, which is a higher maturity level than experimental status.

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

CSPP development is led at the Space Science and Engineering Center at the University of Wisconsin-Madison by James Davies with funding support from the NOAA/NASA Joint Polar Satellite System (JPSS). For more information, please visit the CSPP website:
