S5P_L2__O3_TCL: Sentinel-5P Tropospheric Ozone Columns in the Tropics

Sentinel-5P's TROPOMI instrument provides high-resolution atmospheric composition data from ultraviolet to shortwave infrared wavelengths. Its tropospheric ozone product is derived using two distinct algorithms, the convective-cloud-differential and cloud slicing methods, to calculate columns below 270 hPa and mixing ratios above clouds. This dataset is geographically restricted to the tropical region between -20 and +20 degrees latitude.

Use Cases

• Monitoring tropical tropospheric ozone pollution trends based on daily satellite retrievals.
• Validating chemical transport models using the convective-cloud-differential (CCD) algorithm outputs.
• Studying the correlation between cloud top pressure and ozone concentration using the cloud slicing algorithm (CSA).
• Analyzing spatial and temporal patterns of a key air pollutant and greenhouse gas in the tropics.

Strengths

• Data originates from the dedicated Sentinel-5P atmospheric composition satellite, a joint ESA and Netherlands mission.
• Provides measurements at high spatial, temporal, and spectral resolution across multiple wavelength bands.
• Employs two specialized retrieval algorithms (CCD and CSA) for deriving tropospheric ozone metrics.

Limitations

• Key metadata (row count, column names, exact size) is unspecified across all sources.
• Product retrieval is dependent on measurements with high cloud cover and is restricted to the tropics.
• There is a conflict in the 'last updated' metadata between 2020-07-07 and 2026-04-09.
