Scientists utilize a passive system to measure methane gas in the atmosphere.
The sun is tracked through the day from the roof, and the images from the sun are transmitted into the sensor. There the signal is split into two channels. Differential measurements are then used to analyze each sunspot, and calculate the concentrations at each specific location.
The current setup is designed to study how methane concentrations change over time (morning-to-afternoon, day-to-day, month-to-month, year-to-year). It needs to be studied over time, because there are many factors that can affect the observable data, such as seasonal effects.
This experimental work is useful for evaluating if scientific models are correct. It can be used to monitor global variations in many locations. The scientific community is interested in gathering CO2 and methane data.
