The heat overlay's model calculations depend on a number of calculation-wide parameters. These parameters are available as attributes of the heat overlay and can be modified as such.
| Attribute | Unit | Description |
|---|---|---|
| DATES | milliseconds | Dates define the amount of timeframes and are used to define the day and time for calculating sun angles. |
| HOURLY_RADIATION | Wm-2 / hr | The amount of Sun radiation this hour, measured at a weather station. |
| HOURLY_HUMIDITY | percentage | The relative humidity of the air at this hour, measured at a weather station. |
| SUN_DAILY_MOTION | factor | A factor used in calculating the Atmospheric Temperature from the calculated Urban Heat Island value. |
| HOURLY_TEMPERATURE | °C | The temperature at this hour, measured at a weather station. |
| WIND_SPEED | m/s | The wind speed measured at a weather station at the height of 10 meters above ground. |
| WIND_DIRECTION | ° | The wind direction viewed from above, with 0° corresponding to North, and increasing in a clockwise fashion. |
| DAILY_TEMPERATURE_MIN | °C | Minimum temperature measured at a weather station. |
| DAILY_TEMPERATURE_MAX | °C | Maximum temperature measured at a weather station. |
| DAILY_AVG_RADIATION | Wm-2 / hr | The average of amount of Sun radiation per hour for this day, measured at a weather station. |
| DAILY_AVG_WIND_SPEED | m/s | The daily average wind speed measured at a weather station at the height of 10 meters above ground. |
