S5P_L2__NP_BD3: Sentinel-5P VIIRS Cloud Classification and Radiance Data

Sentinel-5P TROPOMI provides high-resolution atmospheric composition measurements from a satellite launched by the European Space Agency and the Kingdom of the Netherlands. This product combines S5P observations with VIIRS cloud data from the U.S. Suomi NPP satellite, offering pixel-level cloud classifications and sun-normalized radiance statistics. Data collection for this specific product began on August 6, 2019.

Use Cases

• Classifying cloud cover confidence (confidently cloudy, probably cloudy, probably clear, confidently clear) based on VIIRS pixel data.
• Analyzing cloud spatial extent based on scaled field-of-view data accounting for extended cloud coverage.
• Calculating statistical radiance metrics (mean, standard deviation) based on VIIRS sun-normalized radiance in bands M7, M9, and M11.

Strengths

• Provides high spatial resolution data at approximately 5.5km at nadir.
• Integrates measurements from two satellite instruments (TROPOMI and VIIRS) for enhanced cloud characterization.
• Offers data for three scaled fields-of-view to better account for cloud spatial distribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
