Akatsuki UVI Data: Venus Cloud Top UV Albedo and Contrast Time Series

Empirical equigonal UV albedo of Venus as a function of phase angle determined from Akatsuki UVI data. The dataset includes time series of the standard deviation of mesoscale UV contrast and mean brightness at 283 nm and 365 nm wavelengths. Data was authored by Tomoya Suda of The University of Tokyo and includes Level-3 netCDF data corrected for point-spread function, flat-field pattern, and detector temperature dependence.

Use Cases

• Modeling the relationship between phase angle and UV albedo based on the empirical equigonal albedo data.
• Analyzing temporal variation in mesoscale UV contrast based on the standard deviation time series.
• Studying cloud top brightness patterns on Venus using the mean brightness time series data.
• Comparing atmospheric observations at different ultraviolet wavelengths (283 nm and 365 nm).

Strengths

• Data includes observations at two specific ultraviolet wavelengths: 283 nm and 365 nm.
• Data has been corrected for instrumental effects including point-spread function and flat-field pattern.
• Includes both albedo as a function of phase angle and time series of contrast and brightness.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
