Dear Stavros NTAFISthanks for  your help
but  problem is how plot for four time step and in vertical profile(different height or pressure value)same as attach file

Dear Elham, I am giving you a simple code to read and plot a time series for T2m and 10-m wind speed  for two locations defined by "locs", "lats", "lons". You can add more locations if you like or choose a sub-period by defining "it".

; Get variables for 10-m wind

uvmet = wrf_user_getvar(a, "uvmet10", -1)

u = uvmet(0,:,:,:)
v = uvmet(1,:,:,:)

; Get Temp at 2m in Kelvin
tc2 = wrf_user_getvar(a,"T2",-1)
it = 0 ; first time step, ignore it if you want a time-series

locs = (/ "1st Location", "2nd Location" /)  ; define the locations

lats = (/ 37.5938, 40.6401 /)
lons = (/ 23.4375, 22.9444/)

nlocs = dimsizes(locs)
loc = wrf_user_ll_to_ij(a, lons, lats, True)  ; find the indices of the closest WRF grid points to locations

do iloc = 0, nlocs-1

print("Working for " + locs(iloc))

locX = loc(0, iloc) - 1
locY = loc(1, iloc) - 1

wind= sqrt(u(:, locY, locX)*u(:, locY, locX) + v(:, locY, locX)*v(:, locY, locX)) ; replace ":" with "it" if you want one time-step only

temp = tc2(:, locY, locX)   ; if you want only one time step: temp = tc2(it, locY, locX)

print( ""+wind+"   "+temp+"")

end do

regards,

Hi dear ncl usrI want plot some data for example temperature or wind speed in some time step from wrf out data file in one locationhow i should it?Best RegaradsElham
