Abstract :
An inversion method is described to retrieve high-emissivity surface temperatures from microwave and thermal infrared radiometric measurements assuming a horizontally stratified atmosphere. From an error analysis, a surface temperature uncertainty of about 1K can be achieved with a wide set of zenith angles and reasonable measurement uncertainties
