I've toured the HAO facility. They 3 altitude sample points to determine if the CO2 is local or atmospheric. And they use a calibration gas to make sure sensors are working correctly. They also have sites around the world to compare against as well. Here are some details of the measurements and calibrations: http://www.esrl.noaa.gov/gmd/ccgg/about/...ments.html
They also track global changes in fossil fuel burnings because most of the worlds population is the in northern hemisphere so you can see it change with the seasons.
The site on Mauna Loa has been the longest recording CO2 site in the world, it's a pretty amazing place and there is a lot of good science experiments going on up there.
