Two lines of investigation have dealt with surface heat and radiation balance. A study in conjunction with Mamoudou Ba derived surface shortwave and longwave radiation parameters and examined surface albedo as a function of vegetation. Work by Andrew Lare and others resulted in surface heat balance calculations and the impact of rainfall variability on the balance. We are now utilizing this work in land surface modelling.
