Abstract :
We present an algorithm to retrieve land surface temperatures from wideband thermal infrared measurements using the model of Li et al. (1999). Forward simulation and inversion demonstrates the method to be stable in the presence of observation noise. Results from inversions performed using field measurements show that errors are generally less than the uncertainty in the observations
