Moderate wet days wrt 75th percentile of reference period
ecar75p.RdLet infile1 be a time series RR of the daily precipitation amount at wet days (precipitation >= 1 mm) and infile2 be the 75th percentile RRn75 of the daily precipitation amount at wet days for any period used as reference. Then the percentage of wet days with RR > RRn75 is calculated. RRn75 is calculated as the 75th percentile of all wet days of a given climate reference period. Usually infile2 is generated by the operator ydaypctl,75. The date information of a timestep in outfile is the date of the last contributing timestep in infile1.
