The Tropospheric Emissions: Monitoring of Pollution (TEMPO) Nitrogen Dioxide (NO2) Vertical Column Troposphere Beta layer provides information on the amount of nitrogen dioxide in the troposphere. This is provided as the total number of nitrogen dioxide molecules in the tropospheric column of air above one square centimeter on the Earth’s surface. Imagery is available as approximately one-hour scans for daylight hours over North America. The sensor’s native spatial resolution is ~2 km x 4.75 km at the center of TEMPO’s field of regard (FOR) and the Level 3 product resolution is 0.02 x 0.02 degrees. The layer is filtered to display high-quality pixels using the main data quality flag (removing low confidence measurements), solar zenith angle (removing data retrieved at high solar zenith angles), and effective cloud fraction (removing where clouds obscure the tropospheric column) variables. Data are available from May 2024 to present. These data should be considered as beta products per the Beta Product Maturity level defined in the TEMPO validation plan. The products are not optimized for operational use and anomalies may exist. Users should refrain from making conclusive public statements regarding science and applications of the TEMPO data products until the products are designated to be at the provisional validation status according to the validation plan. A readme file describing the data and associated known issues can be found here. Note: Each image is presented with the starting timestamp of the corresponding TEMPO scan. Due to the nature of the TEMPO instrument’s east to west scanning pattern, each image is a composite of measurements taken over a period of 40-60 minutes, depending on the spatial coverage of the scan. |
