OMLER: Earth Surface Reflectance Climatology, 0.5-Degree Grid, 2004-2007

23 wavelengths of Earth's surface Lambert Equivalent Reflectance (LER) in a 0.5 by 0.5-degree global grid. The monthly and yearly climatology is based on statistical analysis of three years of OMI satellite radiance data from October 2004 to October 2007. This product is archived at the NASA Goddard DAAC and provided in HDF-EOS5 format.

Use Cases

• Modeling top-of-atmosphere reflectance in pure Rayleigh atmospheres based on surface LER data.
• Analyzing spectral surface reflectivity trends over a three-year period based on the provided minimum reflectivity.
• Calibrating satellite-derived atmospheric products using the climatological surface reflectance reference.
• Studying geographic variations in Earth's surface reflectance across 23 UV-VIS wavelengths from 309 to 500 nm.

Strengths

• Provides data for 23 specific wavelengths in the UV-VIS spectral range (309-500 nm).
• Offers a defined three-year temporal coverage from October 2004 to October 2007.
• Has a consistent global spatial resolution of 0.5 by 0.5 degrees.
• Includes both monthly and yearly climatology summaries for longitudinal analysis.

Limitations

• Row count and sample data are unavailable, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is limited to cloud-free and aerosol-free conditions, which may not represent all real-world scenarios.
