I want to plot composite map using netCDF4 and python (using basemap)

nc file can be found here. https://www.esrl.noaa.gov/psd/cgi-bin/db_search/DBListFiles.pl?did=59&tid=66777&vid=1498

This nc file has an information of location, time and geopotential height for all location on Earth.

I want to plot a map by composing these information.

For example, suppose I downloaded 'hgt.2010.nc' at the link above, so I have an geopotential height information on a daily basis in 2010 on all globe.

Next, I select the date '2010.01.01', '2010.02.01', '2010.03.01'. Then I want to plot one map by just using average of geopotential heights of three days.

How can I do this? Can you help me by giving some code?
