Erythemal UV irradiance measurements were recorded at Davis Station in Antarctica during the summer of 1998. The dataset includes 10-minute cumulative readings for downwelling solar radiation and irradiance beneath various simulated water column depths using borosilicate glass filters. Data was collected by the Australian Antarctic Data Centre.
Use Cases
- Analyze temporal patterns of downwelling erythemal UV irradiance using the 'date' and 'Davis solar time' columns.
- Model UV attenuation through simulated water depths by comparing the 'downwell' column with filtered readings 'w3.3', 'w5.5', and 'w9'.
- Calculate daily erythemal UV exposure cycles by aggregating 10-minute 'downwell' measurements.
- Assess the performance of neutral density screen filtration by comparing the 'wnd' column with unfiltered 'downwell' data.
- Validate Beer's Law attenuation models for Antarctic seawater using the gradient from 'downwell' through 'w3.3', 'w5.5', to 'w9'.
Strengths
- Provides specific irradiance measurements beneath multiple simulated water depths (1.0, 2.0, 3.0, and 3.6 m).
- Includes a control condition (no erythemal UV) for baseline comparison.
- Data is temporally resolved with 'date' and 'Davis solar time' for 10-minute intervals.
Limitations
- Dataset size is unknown, with no row count or file size provided.
- Temporal coverage is limited to a single summer season in 1998.
- Geographic coverage is restricted to one Antarctic station, limiting generalizability.
