Myhre, G, Kvalevag, MM, Schaaf, CB (2005). Radiative forcing due to anthropogenic vegetation change based on MODIS surface albedo data. GEOPHYSICAL RESEARCH LETTERS, 32(21), L21410.

In this study we use the capabilities of the MODerate Resolution Imaging Spectroradiometer ( MODIS) land surface product to estimate the radiative forcing due to surface albedo changes caused by anthropogenic vegetation changes. We improve the representation of the present surface albedo by using data retrieved from MODIS. The change in surface albedo is based on the current vegetation land cover from MODIS, the MODIS surface albedos for those vegetation types, and a data set for potential natural vegetation. We arrive at a radiative forcing due to anthropogenic vegetation changes of - 0.09 Wm(-2) since pre-agriculture times to present, weaker than most earlier published results for this climate forcing mechanism. This is mainly due to a lower surface albedo associated with cropland and further with the use of MODIS data to allow us to constrain the surface albedo change.
