GHAPS: A new Green House And Pollutant Sensor

Advances in detector arrays, communication technology, global positioning and gas correlation sensors are combined to produce a small, simple, accurate, autonomous gas column sensor with unlimited lifetime. We describe a solar powered, miniature gas correlation sensor that can be placed anywhere that provides unobscured observation of the sun. The sensor will provide column measurements of CH4, CO2 and CO throughout the day, along with estimates of moisture and overcast. This flashlight size device could supply a low cost solution to monitoring the atmospheric abundance of key greenhouse and pollutant gases, including fluxes of gas emanating from areas surrounded by these sensors. The design, implementation strategy and performance estimates are described.
