[ncl-install] Fw: scatsat-1 data plotting

[Mary Haley]

Hello,

I wanted to add to Rick's response because I noticed some graphical
resources are misspelled.
Also, you don't need an array to calculate lat / lon. You can do this using
array arithmetic.

lon = (360./numlon)*(ispan(0,numlon-1,1)+0.5)
lat = (180./numlat)*(ispan(0,numlat-1,1)+0.5)-90

Finally, I added some lines to change the color map, set the contour
levels, and do raster plotting for faster results.

If you continue to have questions, please subscribe to ncl-talk as Rick
described, and send the questions to ncl-talk at ucar.edu.
