Skew-T Virtual Sounding Plotter
A program to generate Skew-T meteorological data plots from GRIB files output by meteorological forecasting models, also known as a virtual sounding. It is intended as an easy-to-use educational tool by students or researchers.
The program uses the UCAR/Unidata NetCDF-Java library for GRIB file reading. Currently it is able to read GRIB1 and GRIB2 files published on the NOAA NOMADS site.
Written for Java 11 and OpenJFX 11. Licensed under the 2-clause BSD license.
Features
- Read GRIB1 and GRIB2 files output by the NOAA RAP, NAM, and GFS forecasting models
- Generate high-quality Skew-T/Log-P plots from temperature and dew point data at various isobaric levels
- Convert relative humidity to dew point as needed
- Calculate values such as lifting condensation level (LCL), K-index, Total Totals, and SWEAT depending on data available
- Output high-resolution (approximately 328 DPI) plot to a PNG file
