Result types (Heat Overlay)
Revision as of 09:28, 16 December 2019 by Rudolf@tygron.nl (talk | contribs)
The Heat Module of a Heat Overlay performs complex calculations and can generate multiple types of results per timeframe. A timeframe in the Heat Overlay correspond to a date and time for which a result will be calculated. This date and time will be relative to the project's time zone.
List of Result Types
Icon | Result type | Unit | Display mode | Description | ||||||
---|---|---|---|---|---|---|---|---|---|---|
BOWEN_RATIO | ratio | Date-Time | The initial bowen ratio of buildings and terrain. Differs for water terrain based on day and night. | |||||||
FOLIAGE | m | Start | The initial and optional calculated foliage height, depending on the source of the foliage height. | |||||||
PET | °C | Date-Time | The calculated physiological equivalent temperature. | |||||||
PET_RELATIVE | °C | Date-Time | The calculated PET temperature subtracted by the calculated atmospheric temperature | |||||||
SHADE | boolean | Date-Time | Indicates whether a cell is in the shade or not based on sun ray calculations. | |||||||
SKY_VIEW | fraction | Start | The calculated sky view factor. | |||||||
SKY_VIEW_AVG | fraction | Start | The calculated average of individual calculated sky view factors. | |||||||
TEMPERATURE_ATMOSPHERE | °C | Date-Time | The calculated atmospheric temperature, based on the UHI, sun motion factor and the measured temperature. | |||||||
UHI | °C | Date-Time | The calculated urban heat island effect. | |||||||
VEGETATION | fraction | Date-Time | The fraction of vegetation per square meter. | |||||||
VEGETATION_AVG | Date-Time | The calculated average vegetation based on the cells' individual vegetation fraction. | fraction | WIND_SPEED | m/s | Date-Time | The wind speed calculated for the height of 1.2 meters above ground. |
Result types can differ in the kind of data they display and in what way that data is recorded. A result type can be monitoring the data in one of the following ways:
- Start: The data is determined at the start of the simulation, and does not change over the course of multiple time steps.
- Date-Time: The data is dependent on the timestep, which corresponds to a date and time. In case the Average timeframe option is selected, the last timeframe will present the average values of all previous timesteps for that particular Result Type.
