TEMPO O2-O2 Gridded Cloud Fraction and Pressure (Provisional)

TEMPO satellite observations provide cloud information on a regular grid covering its field of regard. The Level 3 data files contain effective cloud fraction and cloud optical centroid pressure, derived from combining Level 2 scan cycles using an area-weighted re-gridding algorithm. These provisional data were validated on December 9, 2024 by the LARC_CLOUD organization.

Use Cases

• Analyzing cloud cover patterns based on effective cloud fraction data.
• Modeling atmospheric radiative transfer based on cloud optical centroid pressure.
• Validating climate models using satellite-derived cloud property grids.

Strengths

• Data reached provisional validation on December 9, 2024.
• Derived from combining multiple Level 2 satellite scan cycles.
• Uses an area-weighted re-gridding algorithm for spatial consistency.

Limitations

• Data is labeled as provisional; final validation may be pending.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
