MOPITT carbon monoxide validated using NDACC ground stations

Measurements of carbon dioxide from the MOPITT satellite instrument have been validated using the NDACC network of ground-based measurements. ACOM scientist Rebecca Buchholz and colleagues reported on their study of MOPITT version 6 retrievals using total column CO measurements from ground-based remote-sensing Fourier transform infrared spectrometers (FTSs). MOPITT generally shows a small bias with respect to the ground-based measurements. The ground stations are located worldwide at latitudes ranging from 80° N to 78° S, and are maintained by the Network for the Detection of Atmospheric Composition Change (NDACC).
