Re: How to proceed with already interpolated 3D data?

[Jonathan Callahan <Jonathan.S.Callahan@xxxxxxxx>]

Ding,

It might be worth doing the following in Ferret just to make sure it can read and plot your data.  I always like to check before installing a dataset in LAS.

jaguar callahan> ferret

yes? use coads_climatology
yes? show data
     currently SET data sets:
    1> /home/ja9/tmap/fer_dsets/descr/coads_climatology.des  (default)
 name     title                             I         J         K         L
 SST      SEA SURFACE TEMPERATURE          1:180     1:90      ...       1:12
 AIRT     AIR TEMPERATURE                  1:180     1:90      ...       1:12
 SPEH     SPECIFIC HUMIDITY                1:180     1:90      ...       1:12
 WSPD     WIND SPEED                       1:180     1:90      ...       1:12
 UWND     ZONAL WIND                       1:180     1:90      ...       1:12
 VWND     MERIDIONAL WIND                  1:180     1:90      ...       1:12
 SLP      SEA LEVEL PRESSURE               1:180     1:90      ...       1:12
 
yes? shade airt[l=1]
yes?
 

In your case you'll want to replace 'coads_climatology' with 'YOUR_DATASET'.  Then just specify one of the variables names to the 'shade' command and be sure to choose which K or L index to slice along.  If you get a nice plot then you're ready to install the data into LAS.
