Panoply 2.8.2 - Plot raster images of latitude/longitude-gridded data. (Free)

Panoply plots geo-gridded arrays of latitude-longitude, latitude-vertical or time-latitude data encoded in netCDF, HDF and GRIB format.

Features include:

• Slice specific 2D arrays from multidimensional variables which have more than two dimensions.
• Combine two arrays in one plot by differencing, summing or averaging.
• Menu of 80+ global and regional map projections for lon-lat plots.
• Draw continents outlines or masks on lon-lat plots.
• Apply any CPT, GGR, PAL, or ACT color table for scale colorbar.
• Save plots to disk using GIF, PDF, PNG or PS format.

• Added ability to export lon-lat map plots in KMZ format (for use in, e.g., Google Earth), but only if map uses "Equirectangular" or "Equirectangular (Regional)" projection.
• Bugfix: CPU demand spike caused by programmatically called garbage collection being invoked much too often.
• Bugfix: Construction of variable tables in plot windows was taking far too much time.
• Added partial ability to read color palettes included in HDF5 files. Limited to "STANDARD" or "STANDARD8" palettes using RGB color model.

• Mac OS X 10.4 or later
• Java 1.5 or later.
