SALINAS CASTILLO, Wilver Enrique  e  TREVINO GARZA, Eduardo Javier. Impact of deforestation on the microclimate of the Corona river basin, Tamaulipas, Mexico. Invest. Geog [online]. 2002, n.47, pp.59-76. ISSN 2448-7279.

The research aims to evaluate the potential impacts derived from the accelerated changes in land use and vegetation cover affecting the distribution of incoming solar radiation into sensible and latent heat in a secondary basin located at the central portion of the Tamaulipas state, Mexico. Evidences were found tlîat heat redistribution in some areas within the basin affected the local microclimate, impacting land by favoring desertification processes. The study used information from 1972 land-use maps and a 1998 Landsat satellite image to establish general trends in plant-cover changes. Additionally, time-series modelling and statistical analyses of temperature and rainfall were conducted for five meteorological stations located within the basin's influence area with historical records since 1958.
