NOTES
- DPRA Heat stress report uses only two possible values for the Bowen ratio: 0.4 and 3.0.
- Terrains such as grassland and functions such as trees and vegetation generally have a ratio of 0.4.
- Water is special in the sense that during the day the ratio is 0.4 and at night the ratio is 3.0.
- The other functions and terrains have a Bowen ratio of 3.0
