Workspace Method SurfaceFastem

Description

FASTEM sea surface microwave emissivity parametrization.

The variable surface_props_data must contain these data:
  "Water skin temperature"
  "Wind speed"
  "Wind direction"
  "Salinity"

For some details and comments see FastemStandAlone and surfaceFastem.
