Employing the local Intensity Scaling (LOCI) method to adjust the wet-day frequencies and wet-day intensities of precipitation time series is based firstly on specify an RCM-specific precipitation threshold which implies the number of RCM-simulated days exceeding this threshold matches the number of observed days with precipitation larger than 0 mm. So, if the average number of simulated rainy days of a certain month throughout the control period was bigger than the corresponding observed number, a positive threshold has to be assigned and applied in which all days, for both control and scenario run, with precipitation amount less than the specified threshold are redefined to dry days with 0 mm precipitation.

Applying the concept above, a pragmatic question about the versa case was raised. In other words, what should I do if the simulated number of rainy days for some months of each station was less than the observed?
