CSPP VIIRS/MODIS Reprojection Software Released: An update to the NOAA JPSS Community Satellite Processing Package (CSPP) Polar2grid software for reformatting Visible Infrared Imager Radiometer Suite (VIIRS) Sensor Data Record (SDR) data into reprojected Geographic Tagged Image File Format (GeoTIFF) files and/or Advanced Weather Interactive Processing System (AWIPS) NetCDF 3 gridded files was released this week. The software accepts VIIRS CSPP or Interface Data Processing System (IDPS) SDR HDF5 files as input, and transforms the requested I-Bands, M-Bands or Day/Night band data into high resolution reprojected GeoTIFF files, or a select number of SDR Bands into gridded NetCDF files for display in AWIPS-I or AWIPS-II. This update includes simplified creation of true color images, with the execution of one script that creates both the corrected reflectances, and the true color image in sequence. A bug was also fixed in the corrected reflectance software; missing and saturated data are now handled correctly. This improves the quality of the final true color GeoTIFF image product. This same software package includes the capability to create GeoTIFF files from input NASA Moderate-resolution Imaging Spectroradiometer (MODIS) Level 1B data files as well. (D.

CIMSS Student Invited to EUMETSAT as a Visiting Scientist to Validate IASI Sounding Products: University of Wisconsin graduate student Ms. Jacola Roman was invited to travel as a visiting scientist to EUMETSAT in Darmstadt, Germany for three weeks in August to assist Dr. Thomas August in the validation of atmospheric products derived from the Infrared Atmospheric Sounding Interferometer (IASI) sensor on the MetOp operational polar orbiting platform. EUMETSAT level 2 version 6 represents a major update of the operational product for the retrieval of atmospheric temperature, water vapor, and surface properties from the AMSU/IASI sensor combination. The validation of EUMETSAT level 2 version 6 temperature and water vapor was accomplished using the same methodologies developed at the Cooperative Institute for Meteorological Satellite Studies (CIMSS) for the U.S. Joint Polar Satellite System (JPSS) project. CIMSS students M. Feltz and J. Gartzke provided assistance with the provision validation datasets from the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) and the Department of Energy Atmospheric Radiation Measurement (DOE ARM) sites. Ms. Roman completed her visit with a seminar talk at EUMETSAT titled, 'EUMETSAT IASI LEVEL 2 PWLR V6 PRECIPITABLE WATER VAPOR (PWV) AND WATER VAPOR PROFILE VALIDATION'. (J. Roman, AOS, 608-265-0762, M. Feltz, AOS, 608-265-0762, J. Gartzke, SSEC, 608-265-0762, R. Knuteson, SSEC, 608-263-7974, S. Ackerman, CIMSS, 608-263-3647)

Figure caption: Precipitable Water Vapor fractional error (in percent) of the EUMETSAT Level 2 version 6 products derived from IASI-A and IASI-B on Metop-A, and -B relative to the SuomiNet ground-based GPS receiver network in the 4 by 5 degree region surrounding the DOE ARM Southern Great Plains (SGP) site. The NASA AIRS Level 2 version 6 product is overlaid for comparison. The EUMETSAT IASI Level 2 version 6 and the NASA AIRS Level 2 version 6 products show very similar error characteristics with a wet bias below 10 mm and a dry bias above about 45 mm.
JPSS Validated Stage 1 Maturity Reviews: The Cloud and Cryosphere Teams participated remotely in the Joint Polar Satellite System (JPSS) Validated Stage 1 Maturity Reviews. The purpose of these reviews were to assess if the Cloud and Cryosphere products met the requirements for Validated Stage 1 Maturity. These requirements include demonstration of the meeting of the JPSS product performance specifications over limited conditions. Stage 2 and Stage 3 require both global and seasonal validation. The results of the review will be made available later. (A. Heidinger, E/RA2, 608-263-6757, andrew.heidinger@noaa.gov; J. Key, E/RA2, 608-263-2605, jkey@ssec.wisc.edu)
