NCDC Weather/Climate Toolkit BETA v 3.5.0 Released

The beta version of the National Climate Data Center (NCDC) Weather and Climate Toolkit (WCT) has been released and is now available for download from  This beta release adds support for several new functions including Level 2 and Level 3 Dual-Polarization products like the graphic below.  The tool is available for use in Windows, Mac OS/X and Unix/Linux environments.  I personally use the standalone download because it’s easier to save versions locally to test out the features of the newer release.

NEW Features in Version 3.5 –

Below are the new features from the WCT website:

NEXRAD Dual-Polarization support

The Level-2 Dual-Polarization moments and Level-3 Dual-Polarization products are now supported. For more information on dual-polarization and the new Level-3 NEXRAD products, please refer to:

Isosurface KMZ Generation

The generation and export of KMZ isosurfaces for Radial and Gridded Datasets is now supported. An isosurface is a three-dimensional equivalent of the two-dimensional contour line. Isosurfaces can be generated from gridded data that have a height dimension or Radial volume scan data such as Level-2 NEXRAD. The resulting KMZ can be visualized in KMZ viewers such as Google Earth.

CAPPI for Radial Radar Data

CAPPI (Constant Altitude Plan Position Indicator) – a constant altitude cross-section of Radar data. To create a CAPPI, select the desired CAPPI altitude from the Radial Properties window after loading a Radar volume scan data file. Data exports also allow the selection of a CAPPI altitude instead of a specific elevation angle.
