Matthews Vegetation

Matthews Seasonal Integrated Albedo data set includes four data files for Winter, Spring, Summer and Autumn (January, April, July and October respectively in the Northern Hemisphere; and July, October, January and April for the Southern Hemisphere). They show the seasonal percentage of incoming radiation reflected into space, integrated across the electro-magnetic spectrum. These are based on the vegetation and cultivation intensity maps, rather than being measured directly, and are for snow-free conditions except for permanently snow-covered continental ice
