A portable ground instrument for measuring CO2 and CH4 in the Earth's atmospheric column.
Pandora spectrometer instrument spectroscopy is used to measure columnar amounts of trace gases in the atmosphere. These gases (O3, NO2, CH2O) absorb specific wavelengths of light from the sun in the ultraviolet-visible spectrum.
The primary scientific objective is to provide time/height ozone measurements from near the surface to the top of the troposphere to describe in high-fidelity their spatio-temporal distribution. These high-fidelity measurements provide the GEO-CAPE science team with accurate representations of the PBL and FT ozone structure as proxies for the high time resolved observations from a geosynchronous satellite.
