Abstract
Due to significant anthropogenic changes that have occurred in the last several decades in Bucharest city's landscape, urbanization has become an important factor affecting urban surface parameters, hence in the surface-atmosphere interaction processes, with a great potential to alter the local climate. Land use and land cover (LULC) influence a variety of processes important in characterizing urban /periurban biophysical parameters' quality, including aerosol deposition rates, biogenic emissions, albedo, surface temperatures, climatic parameters and other. Analysis of surface biophysical parameters changes in urban/periurban areas of Bucharest town based on multi-spectral and multi-temporal satellite imagery (Landsat TM, ETM and IKONOS) for 1989 - 2009 period provides the most reliable technique of environmental monitoring regarding the net radiation and heat fluxes associated with urbanization at the regional scale. Investigation of radiation properties, energy balance and heat fluxes is based on information derived from various satellite sensors and in-situ monitoring data, linked to numerical models and quantitative biophysical information extracted from spatially distributed NDVI-data and net radiation. This study attempts to provide environmental awareness to urban planners suggesting that future changes in urban land cover could substantially affect climate by altering biophysical land-atmosphere interactions.
