Polar2Grid Software Version 2.2 Release

Polar2Grid Software Version 2.2 Release

Postby kathys » Thu Jan 25, 2018 6:31 pm

We are pleased to announce new Community Satellite Processing Package (CSPP) Polar2Grid Version 2.2 software is available for the reprojection and gridding of polar orbiter satellite data including S-NPP and NOAA20 VIIRS, MODIS and AVHRR instruments into a variety of output formats including:

- GeoTIFF files,
- Advanced Weather Interactive Processing System (AWIPS) 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.

CSPP Polar2Grid development is led by David Hoese at the Space Science and Engineering Center, University of Wisconsin-Madison with funding support from the NOAA/NASA Joint Polar Satellite System (JPSS).

Polar2Grid Version 2.2 includes a number of updates, including expanding the number of sensors, products and functionality supported.

Key Version 2.2 updates:

• Support for both S-NPP and NOAA20 VIIRS Sensor Data Records (SDRs).
• A new AWIPS NetCDF "scmi" writer has been added that provides a more efficient way of doing full resolution reprojections.
• Added support for CSPP NOAA/STAR Advanced Clear-Sky Processor for Oceans (ACSPO) sea surface temperature products.
• Added support for the CSPP NOAA/STAR Clouds from AVHRR Extended (CLAVR-x) products.
• Added new grid definitions for 300m, 750m and 1km AWIPS SCMI tiled sectors LCC, Polar, Mercator, and Pacific.
• Added a new VIIRS Day/Night Band nighttime enhancement option (hncc_dnb), following the algorithm developed by Stephan Zinke of EUMETSAT. See the installation guide for more information.
• Fixed MODIS navigation calculations over the prime meridian.

In addition, Please Note that the original Polar2Grid bash shell script executions <reader><writer>.bash are being phased out and replaced by a more general script implementation: polar2grid.sh <reader> <writer> . In the future, only the latter implementation will be supported.

Polar2grid Software Features

- The software is modular, robust and efficient.
- Creates standardized output GeoTIFF files. Image default projection is the WGS 84/Platte Carrée coordinate system (Google Earth).
- Execution takes place using simple bash scripts wrapping python; users specify a directory containing the input files, or the files themselves.
- True color and False color reprojections can be created using a single command.
- Software uses high spatial resolution bands for sharpening true color and false color images.
- Accepts proj4 grid definition parameters.
- Users can define their own grids. A grid definition helper script is included with the package.

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

Kathy Strabala and David Hoese
