                         (LPB) are regions with high biodiversity. However, these areas are 
                         characterized by scarce climatological information, complex 
                         orography, and rain-gauge network unevenly distributed. 
                         Interpolated data from the ground station might overcome these 
                         aspects. For this reason, is necessary to identify the best 
                         technique for the spatial interpolation of rainfall. Hence, the 
                         spatial interpolation techniques were applied to annual and 
                         seasonal rainfall in the CBC and LPB. Geostatistical results and 
                         deterministic approaches were compared by cross-validation. 
                         Cokriging with spherical (gaussian) model is the best interpolator 
                         in the CBC (LPB), as indicated by the lowest root mean square 
                         error (RMSE) and a standardized RMSE close to one. The CBC shows 
                         three rainfall cores: the northern, 9,000 mm/year; the 
                         central-southern, 10,000 mm/year; and the southern, 7,000 mm/ 
                         year. The LPB shows a west-east rainfall gradient, with a minimum 
                         to the west (450 mm/ year) and a maximum in the mid-west (2,000 
                         mm/year). To the north of the LPB, rainfall reaches 1,500 mm/year, 
                         while in the south it reaches only 900 mm/year. The results in our 
                         study may be useful for scientists and decision-makers for use in 
                         environmental and hydrological models for the CBC and the LPB.",
