The precipitation varies spatial and temporally, this make difficult to obtain representatives measurements in remotes zones of the country where there are very few installed meteorological stations. The development of satellites remote sensing has allowed to make precipitation estimations for different time scales and at any geographic location, because of that it make possible to develop its estimation at monthlies and annuals scales. The objective of this study was to estimates the monthlies and annual precipitations maps for Nicaragua from MERRA-2 monthly precipitation (NASA). One hundred fifty five points were used distributes in the country, with monthly precipitation information got from the NASA platform The Power Project. The annual maximum daily precipitation records from the Managua Airport gauge were compared with the MERRA-2 products records, getting very low correlation, therefore we consider that is not satisfactory its use to estimates maximum daily precipitations. The monthly precipitations records from 19 pluviometers gauges were compared with the MERRA-2 products records, getting determination coefficients R2 in the interval of 0.56 to 0.79, therefore we consider that the precipitation estimated with MERRA-2 products make good simulation of the monthlies precipitation registered in the gauges.
