Good morning,

I have 6 hourly wind data and I am trying to get the daily averages however I am getting and error when I use calculate_daily_values. I have ncl 6.6.2 installed, can anyone help me? Below is the script used and the output.

Script:
fil1           = addfile("/media/wind/NCEP-DOE_Reanalysis_2/uwnd.10m.gauss.1979.nc<http://uwnd.10m.gauss.1979.nc>","r")
uwnd_practice  = short2flt(fil1->uwnd)


printVarSummary(uwnd_practice)
printMinMax(uwnd_practice, True)

opt           = True
opt at nval_crit = 4

uwnd_daily    = calculate_daily_values(uwnd_practice, "avg", 0, opt)
printVarSummary(uwnd_daily)
printMinMax(uwnd_daily, True)
