[ncl-talk] a number of issues

[Geeta Geeta]

 Hi. 
I have a few questions which are as follows.

1. I have to plot the data for a range of LAT/LON. 
when I plot the data using the command, 
plot=gsn_csm_contour_map_ce(xwks,data,res)
it plots over the entire globe. 
How to select the subset LAT/LON for plotting the data???


2. I plotted the Surface Rain and Surface Precipitation and Total precipitablewater variables from the HDF file. 
2A12.20140602.94247.7.HDF. This is 2A12 TMI data. 

I donot know the difference between these parameters. Can somebody explain???


3. In this dataset, I need to extract two arrays, called ClusterScale (3 dimensional array)and cluster which is 4 dimensional array. 
Below is the header info of these two variables. 
ScanType=CONICAL;
   dimensions:
      nlayer = 28
      ncluster = 100
      nfindex = 13
      nspecies = 6
      nscan = 2919  // unlimited
      npixel = 208
      fakeDim6 = 3
      fakeDim7 = 3
   variables:
      float heightLayerTop ( nlayer )
         units :        km
         hdf_name :     heightLayerTop
                                                                                                                             
      float cluster ( ncluster, nlayer, nfindex, nspecies )
         hdf_name :     cluster
                                                                                                                             


     byte clusterNumber ( nscan, npixel, nspecies )
         hdf_name :     clusterNumber
                                                                                                                             
      float clusterScale ( nscan, npixel, nspecies )
         hdf_name :     clusterScale
                                                                                                                             


 As per the document of 2A12 V7, the hydrometeor profile =clusterScale *cluster

Kindly tell me how can I make the hydrometeor profiles at different heights???
