Function Documentation

◆ tessem_prop_nn()

void tessem_prop_nn ( VectorView ny,
const TessemNN net,
ConstVectorView  nx 
)

Tessem emissivity calculation

When using the default neural network parameter files from the Tessem 2 distribution, the input Vector should contain 5 elements:

  • Frequency (10e9-700e9) in Hz
  • Theta (0-90) Incidence angle in degrees
  • Windspeed (0-25) at 10m in m/s. Higher wind speed can be used but without garantee
  • Surface skin temperature (270-310) in K
  • Salinity (0.0-0.04) in kg/kg
Parameters
[out]nyCalculated emissivity.
[in]netNeural network parameters.
[in]nxInput data.
