[ncl-talk] Fw: script for daily average

[Muhammad Omer Mughal]

Hi


I tried to use the suggestion provided by Dennis below and it shows the error.I am using NCL version 6.4.0. I am repeating the steps here for convenience.

load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRF_contributed.ncl"

a=addfile("wrfout_d05_2016-04-01_00:00:00","r")

 tc2= wrf_user_getvar(a,"T2",-1)

nDim    = 0

tc2DayAvg= calculate_daily_values(tc2, "avg", nDim, False)


At this stage I get the following error

fatal:No coordinate variable exists for dimension (Time) in variable (x)
fatal:["Execute.c":8640]:Execute: Error occurred at or near line 18125 in file /usr/local/ncl-6.4.0/lib/ncarg/nclscripts/csm/contributed.ncl

So I try to do the following to correct this error

tc2 at Time=wrf_times_c(a->Times,0)

and repeat the command but I still receive the same error as above.


I would appreciate the help depending upon your convenience.

I am not sure what you were doing but *read the following documentation":

https://www.ncl.ucar.edu/Document/Functions/Contributed/calculate_daily_values.shtml
requires 6.4.0

========
  nDim    = 0
  tc2DayAvg= calculate_daily_values(tc2, "avg", nDim, False)
  tc2DayAvg at description = "Daily Mean: " + tc2 at description

  printVarSummary(tc2DayAvg)
  printMinMax(tc2DayAvg,0)
  print("-----")

Hi


I wrote the following script to calculate the daily averages


a=addfile("./wrfout_d05_2016-04-01_00:00:00","r")
tc2= wrf_user_getvar(a,"T2",-1)
tc2_dims=dimsizes(tc2)
ntim=tc2_dims(0)
nlat=tc2_dims(1)
nlon=tc2_dims(2)

ndays=ntim/24

tc2D=reshape(tc2,(/ndays,nlat,nlon/))
copy_VarAtts(tc2,tc2D)
tc2_hr_avg=dim_avg_n_Wrap(tc2D,0)

printVarSummary(tc2_hr)

but I am seeing the following error


input dimension sizes cannot conform to dimensions of input array
