%X The main objective of this study was the determination of the surface albedo to Forquilha Basin in Ceará, Brazil. It was used four images of the Landsat 5 - Thematic Mapper satellite, obtained in September, 1985, 1996, 1997 and 2004. The determination of the surface albedo was done according to procedures of algorithm SEBAL (Surface Energy Balances Algorithm for Land), which is based on the radiance of Landsat 5- TM channels (1, 2, 3, 4, 5 and 7). Results showed that the albedo has decreased in a long period of time. The highest values observed of albedo was in the vegetation located on the margins of rivers.
