Carbon Dioxide test gas cylinders at NOAA observatory
NOAA's atmospheric and space observatory, at 3400 meters on the northeast flank of Mauna Loa volcano in Hawaii. The observatory consists of 10 buildings from which up to 250 different atmospheric parameters are measured. Measuring carbon dioxide at this location begun in 1958. Air is collected continuously near the top of a 40 m tower and analyzed for CO2 content every minute by both Scripps Oceanographic Institute and NOAA. The accuracy of readings is tested by periodically measuring known quan
