Panoply is a Java application which plots geo-gridded arrays from netCDF, HDF and GRIB datasets. Slice and plot specific latitude-longitude, latitude-vertical, or time-latitude arrays from larger multidimensional variables. Combine two arrays in one plot by differencing, summing or averaging. Plot lon-lat data on a global or regional map (using any of over 75 map projections) or make a zonal average lineplot. Overlay continent outlines or masks on lon-lat plots. Use any CPT, GGR, PAL, or ACT color table for scale colorbar. Save plots to disk in GIF, PDF, PNG or PS form. To be plotted by Panoply, dataset variables must be tagged with metadata information using a convention such as CF.
