USGS Uses LI-COR Instruments To Monitor Current Volcanic Activity

October 6, 2004 - Lincoln, NE

The United States Geological Survey (USGS) is reporting on their website that part of their monitoring of current volcanic activity, at various locations in the United States, includes data gathered by an aircraft using "a small infrared carbon dioxide analyzer (LI-COR), (as) a standard method for measuring carbon dioxide emission rates at restless volcanoes. The amount of carbon dioxide gas (CO2) in a plume is flying the instrument through the plume several times so that it can continuously sample an entire cross section of the plume."
