Precipitation information plays an important role in calculating aquifer nutrition using mathematical models. In recent years, with the availability of satellite precipitation data, especially TRMM and GPM satellites, new and innovative methods have been developed to overcome the lack of access to precipitation data. However, barriers such as data uncertainty also limit these methods. In this study, after correcting the satellite data error, this information was used as a feed parameter to MODFLOW code, and the groundwater level uncertainty was calculated by different Coppola functions. Examination of groundwater model outputs showed a 50% reduction in root mean square error index (RMSE). It is worth noting that about 90% of the aquifer had a difference of less than 10%, about 8% had a difference of 20 to 30% and about 2% of the aquifer had an approximate difference of 80% of the observational data ratio. The mentioned results show the proper performance and with a reliability coefficient of over 90% of the Coppola functions in calculating the groundwater level uncertainty using satellite precipitation data as the feeding parameter.
