I'm looking into running some continuous simulations in InfoSWMM using several years of historical precipitation data. I've found several sources stating that .dat data obtained from NOAA's National Climatic Data Center (NCDC) is recognized and used by InfoSWMM, yet when I try it I get errors. Has anyone been successful running continuous simulations with data from the NCDC and how did you get it to work? Are there other sources of precipitation data that InfoSWMM can recognize and use for a continuous simulation? Any comments and tips would be greatly appreciated. Thanks.
