The observatory operates a ground-based high-resolution Fourier transform spectrometer and measures the amount of carbon dioxide, methane, carbon monoxide, nitrous oxide and other trace gases in the Earth’s atmosphere. The station is part of an international network which validates satellite data, such as those from greenhouse gases observing satellite (GOSAT, Japan), Orbiting Carbon Observatory 2 (OCO-2, USA), and the Chinese Carbon Dioxide Observation Satellite (TANSAT).
