View source for Model attributes (Heat Overlay)

The [[Heat_(Overlay)|heat overlay's]] model calculations depend on a number of calculation-wide parameters. These parameters are available as [[attribute]]s of the heat overlay and can be modified as such.

! Description
|-
| [[Averaged last result (Heat Overlay)|AVERAGED_LAST_RESULT]]
| {{boolean}}
| Whether to ignore the date-time setting for the last calculated timeframe, and show an average of the results of all preceding timeframes instead.
|-
| [[Dates_(Heat_Overlay)|DATES]]
| milliseconds
| Dates define the amount of timeframes and are used to define the day and time for calculating sun angles.
|-
| [[Hourly_radiation_(Heat_Overlay)|HOURLY_RADIATION]]
| Wm<sup>-2</sup> / hr
| The amount of Sun radiation this hour, measured at a [[Weather station (Heat Overlay)|weather station]].
|-
| [[Hourly_humidity_(Heat_Overlay)|HOURLY_HUMIDITY]]
| percentage
| The relative humidity of the air at this hour, measured at a [[Weather station (Heat Overlay)|weather station]]. 
|-
| [[Sun_daily_motion_(Heat_Overlay)|SUN_DAILY_MOTION]]
| factor
| A factor used in calculating the Atmospheric Temperature from the calculated Urban Heat Island value.
|-
| [[Hourly temperature (Heat Overlay)|HOURLY_TEMPERATURE]]
| °C
| The temperature at this hour, measured at a [[Weather station (Heat Overlay)|weather station]].
|-
| [[Wind speed (Heat Overlay)|WIND_SPEED]]
| m/s
| The wind speed measured at a [[Weather station (Heat Overlay)|weather station]] at the height of 10 meters above ground. 
|-
| [[Wind direction (Heat Overlay)|WIND_DIRECTION]]
| [[Geo angle]]
| The wind direction viewed from above, with 0° corresponding to north, and increasing in a clockwise fashion.
|-
| [[Daily temperature min (Heat Overlay)|DAILY_TEMPERATURE_MIN]]
| °C
| Minimum temperature measured at a [[Weather station (Heat Overlay)|weather station]].
|-
| [[Daily temperature max (Heat Overlay)|DAILY_TEMPERATURE_MAX]]
| °C
| Maximum temperature measured at a [[Weather station (Heat Overlay)|weather station]].
|-
| [[Daily avg radiation (Heat Overlay)|DAILY_AVG_RADIATION]]
| Wm<sup>-2</sup> / hr
| The average of amount of sun radiation per hour per square meter for this day, measured at a [[Weather station (Heat Overlay)|weather station]].
|-
| [[ Daily avg wind speed (Heat Overlay)|DAILY_AVG_WIND_SPEED]]
| m/s
| The daily average wind speed measured at a [[Weather station (Heat Overlay)|weather station]] at the height of 10 meters above ground.
|-
| [[ Sun_altitude_(Heat_Overlay)|SUN_ALTITUDE]]
| °
| The sun angle up from the horizon.
|-
| [[ Sun_azimuth_(Heat_Overlay)|SUN_AZIMUTH]]
| [[Geo angle]]
| The angle along the horizon, with 0° corresponding to north, and increasing in a clockwise fashion
|}

==Notes==
* The [[Sun_altitude_(Heat_Overlay)|sun altitude]] and [[Sun_azimuth_(Heat_Overlay)|azimuth]] are calculated automatically based on the project world location and the date.
* Some model attributes have to be based on a reference [[Weather_station_(Heat_Overlay)|weather station]].
