  abstract = {{T}he use of appropriate space and time scales is fundamental to model the water budget in mountainous regions and to give appropriate replies to the initial requests. {H}owever, at a daily scale, the determination of precipitation behavior is not an easy task due to its high variability in mountainous areas. {S}even years (2001-2008) of accurate precipitation maps (1km ground resolution) have been produced for the monsoon season over the {K}oshi {R}iver basin ({N}epal) to be used for hydrological modeling. {D}ue to field and topographical constraints, the geostatistical method of ordinary cokriging interpolation ({OCK}) was used to compute precipitation grids over a 57,800km2 basin with a rain gauge network made of 47 stations. {U}sing elevation as a covariable, regionalization models were run to produce 976 daily precipitation grids. {T}hey describe temporal and spatial variability close to observed data. {C}omparisons of the {OCK} results to an {A}phrodite's reference grid (resolution of 25km) show that the {OCK} grids are characterized by a higher spatial variability. {B}oth {OCK} and {A}phrodite data sets underestimate observations, with {OCK} grids showing the best fit to observed data. {H}owever, the {OCK} method, with an eventual adaptation of the cokriging model, appears consistent for situations where the resolution of the precipitation's spatial distribution is insufficient and an alternate explaining variable such as elevation is available.},
