The Global Pressure and Temperature model. This model is an empirical model that provides the temperature and the pressure depending the latitude and the longitude of the station.

The Global Pressure and Temperature model is based on spherical harmonics up to degree and order of 9. The residual values of this model can reach 20 hPa for pressure and 10 ° C for temperature. They are significant for higher latitudes and small near the equator (Böhm, 2007)

Deprecated.

Build a new instance.

At the initialization the values of the pressure and the temperature are set to NaN. The user has to call weatherParameters(double, AbsoluteDate) method before using the values of the pressure and the temperature.

This method uses the default data context.

Parameters:

latitude - geodetic latitude, in radians

longitude - geodetic longitude, in radians

bodyFrame - the frame to attach to the ellipsoid. The origin is at the center of mass, the z axis is the minor axis.

Description copied from interface: WeatherModel

Calculates the weather parameters of the model. In order to obtain the correct values of the parameters this method has to be call just after the construction of the model.

Specified by:

weatherParameters in interface WeatherModel

Parameters:

height - the height of the station in m

date - current date
