| BOWEN_RATIO | ratio | Describes the rate of heat transfer for a surface that has moisture as a factor. |
The Bowen ratio[1] is a property of a surface, specifically the ratio between two types of heat transfer (sensible heat and latent heat). The wetter the surface, the lower the ratio.
Notes
- The DPRA Heat stress report uses only two possible values for the Bowen ratio: 0.4 and 3.0.
- By default, Functions such as trees and vegetation generally have a ratio of 0.4. Other functions have a ratio of 3.0.
- The value must be in the range of 0.001 to 10.
