Table 1.
Average direct, diffuse, and reflected UV as measured in UV Index Units (n=487 measurement points)
| Type of UV1 | Mean | sd | Maximum2 | Correlation Between Measures3 |
|---|---|---|---|---|
| Direct UV | 2.63 | 2.21 | 10.0 | 0.97 |
| Diffuse UV | 1.84 | 1.52 | 8.0 | 0.94 |
| Reflect UV | 1.49 | 1.31 | 9.5 | 0.90 |
| Total UV | 1.99 | 1.62 | 8.0 |
1
The two readings taken at each measurement were averaged prior to calculating mean reading; total UV is the mean of all six readings at each measurement.
2
Minimum value for all measures was 0.0
3
Pearson correlations between the two measures taken at each measurement.
