VCG netCDFCFPReader

Description

Details

The netCDFCFPReader is designed to work with netcdf data that uses pressure levels instead of metres as its third dimension. Therefore, it uses the barometric formula.
The exact calculations are for pressure levels lower than 11,000 metres: geometricHeight $= -44330.76923 * (\text{pressure} / 101325)^{0.1907107065} - 1.$
And for calculations up to 20,000 metres: geometricHeight $= (8.31432 * 288.15 * \log(\text{pressure} / 101325)) / (-9.80665 * 0.02889644).$
Another possibility the reader offers, is to calculate the geometric height in regard to the geopotential. In this case, the user has to determine which data array is the geopotential.
Eventually, a scaling option is available, too. This will scale the data in the according x-, y- and z-dimension. If nothing is specified, the default is no scaling at all.
In all cases the pressure levels, previously stored on the z-axis, are saved in a new data array, called "lev".
