[ncl-talk] data_extraction

[Dennis Shea]

??? This not an NCL issue. Please look at your data.

data = a->CERES_SW_TOA_flux___upwards(:)
printVarSummary(data)    ; <===== data[*] one dimension

Variable: data
Number of Dimensions: 1
Dimensions and sizes:    [time | 111455]
Coordinates:
            time: [16526.33308267314..16859.88428081991]


=====
Where is 'data&lat'  ?

You would need:  data(time,lat,lon)

lat1d = ndtooned(conform(data,data&lat,0))
lon1d = ndtooned(conform(data,data&lon,1))

Good ,luck
