[Kunal Bali]

Try this


              f = addfile("*inputfile*.nc","r")
              x = f->*variable_name*
              printVarSummary(x)

              opt = True
              opt at nval_crit = 12   ; require at least 12 values for the
"avg" is calculated.

              xMon = *calculate_monthly_values* (x, "avg", 0,opt)  ;
convert daily to monthly
              printVarSummary(xMon)

             ; for generating output in netcdf if it is required
              diro = "./"
              filo = "merge2.nc"
              ncdf = addfile(diro+filo ,"c")
              filedimdef(ncdf,"time",-1,True)
              ncdf->xMon=xMon
