@Deprecated public class GlobalPressureTemperature2Model extends GlobalPressureTemperature2 implements WeatherModel
Deprecated.The Global Pressure and Temperature 2 (GPT2) model. This model is an empirical model that provides the temperature, the pressure and the water vapor pressure of a site depending its latitude and longitude. This model also provides the ah and aw coefficients used for theVienna 1
model.The requisite coefficients for the computation of the weather parameters are provided by the Department of Geodesy and Geoinformation of the Vienna University. They are based on an external grid file like "gpt2_1.grd" (1° x 1°) or "gpt2_5.grd" (5° x 5°) available at: link
A bilinear interpolation is performed in order to obtained the correct values of the weather parameters.
The format is always the same, with and example shown below for the pressure and the temperature.
Example:
