TEMPO Solar Irradiance Measurements from Reference Diffuser

Provisional validation was reached on December 9, 2024. Level 1 reference irradiance files provide solar irradiance measured using a reference solar diffuser for all North-South cross-track pixels. The data includes radiometrically and wavelength calibrated solar irradiance for UV and visible bands, noise estimates, wavelength grids, viewing geometry, and quality flags.

Use Cases

• Validate satellite instrument calibration based on reference solar diffuser measurements.
• Analyze solar irradiance variability across the UV and visible spectrum.
• Assess measurement noise levels for downstream data quality.
• Model solar viewing geometry for specific observation conditions.
• Apply quality flags to filter unreliable irradiance data points.

Strengths

• Data includes radiometric and wavelength calibration for UV and visible bands.
• Product reached provisional validation on December 9, 2024.
• Files contain ancillary information like noise estimates, wavelength grids, and quality flags.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to nasa_earthdata.
