The Precipitation Conversion and Analysis Tool (PACT) is a useful tool for analyzing erosive storm events and for building climate input files for numerical simulation modles. The full functionality of PACT includes not only the disaggregation of storms focusing on the parameters storm duration, storm amount, time to peak intensity and ratio of peak intensity to average intensity but also the possibility of combining measured rainfall data with data from different sources or sensors covering parameters like humidity, solar radiation, wind velocity, wind direction and dew point. The climate input file for the WEPP (Water Erosion Prediction Project) model covering input parameters for one year can be facilitated within one single workflow in an efficient way.
