ResumoA temporal-spatial analysis is made of the effect of an underwater artificial air diffusion system for the period 2008-2011, on the water quality of Embalse San Roque, Córdoba, through field data and LANDSAT5-TM satellite imagery. The temperature estimated using TM6 band, resulting with a determination coefficient of 0.94 and a mean square error of 0.4 o C. A multiple regression model was used to calculate log(chlorophyll-a) by means of TM1 and TM4 bands, obtaining a determination coefficient of 0.64 which was validated with a control group with and agreement equal 83 %. The processed images show the localized effect of the underwater artificial air diffusion system, improving the water quality in their neighbours.
