So far, best program for plotting the GPS data, still looking for a program for the aircraft data. (The aircraft data works with ncBrowse, but its plotting it vs. time and not alt.)

• Open ncBrowse, using the command: ncBrowse
• Go to file, open file
• Find the file you need, it must end in .nc
• After you loaded the file, click on New Map
• Here you can choose your x and y-axis variables by dragging them to the proper spot
• Once variables have been selected, name your plot and hit done
• Now on the main screen, scroll to the bottom of the variable list to find the new plot
• Double click to open plot and Parameter Editor

Can also just double click on a variable from the list to plot without making a new map.

ncBrowse is also helpful when looking at the structure and organization of an nc file. You can view all the data as a tree or as a table for clarity (this option is under the view tab).
