             abstract = "The present study aims to study the differences in the behavior of 
                         important variables such as albedo (\α) and NDVI (normalized 
                         difference vegetation index) in the Caatinga area in recovery 
                         (CREC) and degraded (CDEG) in the state of Para{\'{\i}}ba. 
                         Variables were estimated from MODIS (Moderate Resolution Imaging 
                         Spectroradiometer) data on the Terra satellite and then compared 
                         to field measurements. The estimates showed higher values of 
                         albedo for the CDEG when compared to CREC, evidencing that in the 
                         CREC there must be a greater availability of energy to carry out 
                         the physical processes. Comparisons between measurements and 
                         albedo estimates resulted in percentage errors ranging from 12% on 
                         average. The NDVI estimation was also satisfactory, which resulted 
                         in higher values for the CREC, besides showing a negative 
                         correlation with the surface temperature values, proving the 
                         expected, since in the areas where NDVI is larger there is a 
                         reduction in the Surface temperature due to increased soil cover. 
                         Thus, we prove the success of using the MODIS sensor for the 
                         present study, in order to analyze the differences resulting from 
                         the change in soil cover.",
