cligen reports max monthly and not averages

image

...I want to point out that the grid met data has an error so it will be good to use it carefully. I found that instead of providing the monthly av precipitation grid met data (downloaded from the WEPP cloud) shows the monthly maximum precipitation (attached). I do not know how much influence (if any) it has on the simulated outputs of WEPP. But I thought of giving you a heads up on that.

Here I edited the monthly precip values

looks like wepp doesn't use them.

 xm - no. of calender days for the month
 prw(12,1)   - monthly probability of wet day after wet day
 prw(12,2)   - monthly probability of wet day after dry day
 c     rst(i,j)    - Array Of Monthly precipitation stats.
c                       dim1: month 1..12
c                       dim2: 1=mean of daily rainfall
c                               mean liquid equivalent precipitation
c                               depth (inches) for a day precipitation
c                               occurs (by month) [=avg total precip
c                               for month / # wet days in month]
c                             2=std deviation of daily rainfall
c                               standard deviation of the daily precip
c                               value (inches) (by month)
c                             3=skew coefficient of daily rainfall

monthly averages don't match calculations from daily values image

this is probably a fyi issue
