[ncl-talk] unit confusion for grad_Latlon_cfd operator

[Dennis Shea]

You mean: *grad_latlon_cfd*
<http://www.ncl.ucar.edu/Document/Functions/Contributed/grad_latlon_cfd.shtml>

Than answer is /meter

>From Example 1:

  gradLatLon  = *grad_latlon_cfd* (T, T&lat T&lon, True, False)

  T_grad_lat  = gradLatLon*[0]*    ; for clarity; explicitly extract
variables from returned 'list'
  T_grad_lon  = gradLatLon*[1]*
  *delete* <http://www.ncl.ucar.edu/Document/Functions/Built-in/delete.shtml>(gradLatLon)

; replace the generic attributes with more specific attributes

  T_grad_lon at long_name = "longitudinal gradient (derivative)"
  T_grad_lat at long_name = "latitudinal gradient (derivative)"
  T_grad_lat at units     = *"K/m"*
  T_grad_lon at units     = *"K/m"*

====

Also: I see a documentation error in Example 2

SST_grad_lat at units = "C/km"

should be

SST_grad_lat at units = "C/m"
