UV Aerosol Absorption Measurements for PACE Satellite Validation

Three Modified Yankee Multi-Filtered Rotating Shadow Band Spectrometers (M-MFRSR) will be deployed at three AERONET sites to measure aerosol absorption properties at 340nm and 380 nm. The dataset is produced by the National Aeronautics and Space Administration for validating the PACE satellite mission, with a planned update in March 2026. It derives parameters like single scattering albedo and aerosol absorption optical depth using AERONET data as input.

Use Cases

• Validating aerosol absorption optical depth (AAOD) retrievals from the PACE satellite.
• Deriving single scattering albedo (SSA) using multi-spectral planar irradiance measurements.
• Analyzing correlations between aerosol optical depth (AOD) and UV absorption properties.
• Studying spatial variation of aerosol properties across three operational AERONET sites.

Strengths

• Data collection is integrated with the established AERONET network, leveraging its standardized calibration and processing.
• Measurements target specific UV wavelengths (340nm and 380 nm) critical for aerosol absorption studies.
• The dataset is designed for a specific validation purpose (PACE mission), ensuring focused relevance.

Limitations

• Key structural details like row count, column names, and exact file size are unavailable across all sources.
• Sources conflict on the license, with datagov specifying 'other-license-specified' while nasa_earthdata lists none.
• The dataset appears to be planned/future data, as descriptions use 'will be deployed'.
