I’ve just added Panoply to the list of data analysis applications. Panoply is an application from NASA that plots geo-gridded and other arrays from netCDF, HDF, GRIB, and other datasets. You can:-

• Slice and plot geo-gridded latitude-longitude, latitude-vertical, longitude-vertical, or time-latitude arrays from larger multidimensional variables.
• Slice and plot "generic" 2D arrays from larger multidimensional variables.
• Slice 1D arrays from larger multidimensional variables and create line plots.
• Combine two geo-gridded arrays in one plot by differencing, summing or averaging.
• Plot lon-lat data on a global or regional map using any of over 100 map projections or make a zonal average line plot.
• Overlay continent outlines or masks on lon-lat map plots.
• Use any of numerous color tables for the scale colorbar, or apply your own custom ACT, CPT, or RGB color table.
• Save plots to disk GIF, JPEG, PNG or TIFF bitmap images or as PDF or PostScript graphics files.
• Export lon-lat map plots in KMZ format.
• Export animations as AVI or MOV video or as a collection of individual frame images.
• Explore remote THREDDS and OpenDAP catalogs and open datasets served from them.
