Surface albedo is one of the most important biophysical parameter responsible for energy balance control and the surface
temperature and boundary-layer structure of the atmosphere. Forest land surface albedo is also highly variable
temporally showing both diurnal as well as seasonal variations. In forest systems, albedo controls the microclimate
conditions which affects ecosystem physical, physiological, and biogeochemical processes such as energy balance,
evapotranspiration, photosynthesis. Due to anthropogenic and natural factors, land cover and land use changes result is
the land surfaces albedo change. The main aim of this paper is to investigate the albedo patterns due to the impact of
atmospheric pollution and climate variations of a forest ecosystem Branesti-Cernica, placed to the North-East of
Bucharest city, Romania based on satellite Landsat ETM+, IKONOS and MODIS data and climate station observations.
Our study focuses on 3 years of data (2003-2005), each of which had a different climatic regime. As the physical
climate system is very sensitive to surface albedo, forest ecosystems could significantly feedback to the projected climate
change modeling scenarios through albedo changes. The results of this research have a number of applications in
weather forecasting, climate change, and forest ecosystem studies.
