CSPP Polar2Grid Reprojection Software V2.0 for VIIRS, AVHRR and MODIS

We are pleased to announce a new release (Version 2.0) of the Joint Polar Satellite System (JPSS) Community Satellite Processing Package (CSPP) Polar2Grid software for reformatting VIIRS, AVHRR and MODIS calibrated data into high resolution reprojected:

    - GeoTIFF files,
    - Advanced Weather Interactive Processing System (AWIPS) NetCDF3 gridded files. AWIPS is the visualization and analysis tool used operationally by the US National Weather Service (NWS),
    - Keyhole Markup language Zipped (KMZ) files,
    - HDF5 files, and/or
    - Binary files.
What is new in Polar2Grid Version 2.0 release?

Polar2Grid Version 2.0 is a significant revision of the original software. Because of the expansion of input and output products supported, execution is now more complex; commands that you may have used in previous versions may require modifications. Wherever possible, we have tried to maintain consistency of execution across all front and back end data sets.

    * Support for AVHRR Level 1b from NOAA-18, NOAA-19, Metop-A and Metop-B satellites is now included.
    * KMZ, HDF5 and binary output formats can be created.
    * A new dynamic VIIRS Day/Night Band enhancement option, provided by Dr. Curtis Seaman of the Cooperative Institute for Research in the Atmosphere (CIRA), is now available.
    * MODIS corrected reflectance software execution is now included as part of true color and false color image creation.
    * Output file naming conventions have changed to reflect the vast number of data and products that are supported.
    * MODIS L1B file naming conventions can be either IMAPP or NASA archive.
    * VIIRS and MODIS 24 bit false color image creation is now supported.
    * Users must now explicitly provide the input SDR matching geolocation files in the file argument list.
    * Because of the improvement in efficiency of the software, the --num-procs optional argument is no longer supported.

CSPP Polar2grid Software Features

    - Accepts VIIRS CSPP or IDPS Sensor Data Record (SDR) HDF5 files as input.
    - Creates standardized output GeoTIFF files. Image default projection is the WGS 84/Platte Carrée coordinate system.
    - Execution takes place using simple bash scripts; users specify a directory containing the SDR files, or the files themselves.
    - Software uses I-Bands to sharpen the M-Bands for high resolution true color and false color image file generation.
    - If more than one contiguous granule is provided as input, an aggregated output image file will be created.
    - Accepts proj4 grid definition parameters.
    - Users can define their own grids. A grid definition helper script is included with the package.

This open source software was developed by a team at the University of Wisconsin, led by David Hoese.

This software package is supported on 64 bit Intel Linux platforms. Source code, binaries, execution scripts and documentation are included at the CSPP website:
