GRASP-AOD: Aerosol Optical Depth Validation Data from 30 AERONET Sites

GRASP-AOD validation data processed from 30 AERONET sites using GRASP v1.0.0 following the methodology of Torres et al. 2017 and Torres et Fuertes 2020. The dataset includes 31 files, with 30 files describing the AERONET sites and one file (aureole_Granada.csv) used for GRASP-AUR testing. The data was authored by Benjamín Torres of the Centre National de la Recherche Scientifique.

Use Cases

• Validate aerosol optical depth retrieval algorithms based on spectral optical depth measurements.
• Analyze aerosol size distribution properties based on fine and coarse mode median radius columns.
• Assess the performance of the GRASP-AOD code using long-term AERONET data.
• Study the relationship between aerosol volume concentration and effective radius.

Strengths

• Data from 30 distinct AERONET sites provides a multi-location validation basis.
• Includes 31 files with one dedicated to a specific test case (GRASP-AUR).
• Column list suggests detailed aerosol microphysical and optical properties.

Limitations

• Row count and dataset size are unknown, limiting suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
