TEMPO Nitrogen Dioxide (NO2) Tropospheric Vertical Column August 2023-September 2025

Description

The Tropospheric Emissions: Monitoring of Pollution (TEMPO) Nitrogen Dioxide Vertical Column Troposphere Provisional layer provides information on the amount of nitrogen dioxide in the troposphere, available as approximately one-hour scans for daylight hours over North America, from August 2023 to September 2025. These data should be considered as provisional products, which are potentially ready for testing by operational users and may be suitable for scientific publication. The data is obtained from NASA's Atmospheric Science Data Center (ASDC) .

Methodology

The Tropospheric Emissions: Monitoring of Pollution (TEMPO) Nitrogen Dioxide Vertical Column Troposphere 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 (units: molecules/cm^2). Nitrogen dioxide Level 3 files provide trace gas information on a regular grid. Level 3 files are derived by combining information from all Level 2 files constituting a TEMPO East-West scan cycle, using an area-weighted re-gridding approach. The data have been converted from their native file format (netCDF4) to Cloud Raster Format (CRF).
