[ncl-talk] all nan after dim_avg_n_Wrap

[Dennis Shea]

The source array is:  [model | 18] x [time | 228] x [lat | 360] x [lon |
720]

The output array from:

wetland_CH4_emissions = dim_avg_n_Wrap(wetland_CH4_emissions_ens,0)

should be 3-dimensions: [time | 228] x [lat | 360] x [lon | 720]

You show 4-dimensions.
