TROPOMI Carbon Monoxide (CO)

The TROPOMI carbon monoxide (CO) retrieves the daily global abundance of CO under clear-sky and cloudy-sky using the 2.3 µm spectral range of the shortwave infrared (SWIR). Clear-sky observations are sensitive to tropospheric boundary layer CO, while cloudy atmospheres modify column sensitivity based on light path variations. Total-column averaging kernels for clear-sky and cloudy conditions provide vertical sensitivity insights. Carbon Monoxide Level 2 data product is available for Offline (OFFL), Near Real Time (NRTI), and Reprocessed (RPRO) timeliness. The NRTI data is available within 3 hours, while OFFL is a few days after acquisition. The product provides total column averaging kernels for individual retrievals, crucial for validation purposes. Users are advised to use data with qa_value > 0.5.
