FIFE Atmospheric Correction Coefficients for Satellite Data

ORNL_CLOUD provides coefficients for correcting atmospheric effects in satellite radiometric data from the FIFE project. These coefficients, generated using the Fraser and LOWTRAN 7 models, are inputs for algorithms that derive surface reflectance from raw satellite and aircraft measurements. The dataset is hosted on multiple platforms, with metadata indicating updates as recent as 2026.

Use Cases

• Correcting radiances measured by aircraft or satellites using the Fraser algorithm coefficients.
• Predicting atmospheric transmittance and background radiance using LOWTRAN 7 model outputs.
• Deriving ground surface reflectance from FIFE level-1 satellite imagery products.
• Providing algorithm inputs for estimating geophysical and biophysical parameters from remotely-sensed data.

Strengths

• Coefficients are derived from established scientific models (Fraser and LOWTRAN 7).
• Dataset is curated by the FIFE Information System (FIS) as part of a staff science collection effort.
• Its presence on multiple authoritative platforms (nasa_earthdata, datagov) indicates validation and importance.

Limitations

• Specific column names, row counts, and dataset size are unknown across all sources.
• Sources conflict on the last updated date, reporting both 1989-10-13 and 2026-03-12.
