The following data types and ranges are available. The data is reported in the SEND DATA message.
| Data type | Format | Description |
|---|---|---|
| Grip | f32 |
Grip value Range: 0.09 ... 0.82 Missing data: NaN |
| Water layer thickness 1 | f32 |
Water layer thickness Range: 0 ... 60 mm (0 ... 2.36 in) Missing data: NaN |
| Ice layer thickness 1 | f32 |
Ice layer thickness Range: 0 ... 60 mm (0 ... 2.36 in) Missing data: NaN |
| Snow layer thickness (water equivalent) 1 | f32 |
Snow layer thickness (water equivalent) Range: 0 ... 60 mm (0 ... 2.36 in) Missing data: NaN |
| Surface temperature | f32 |
Measured road surface temperature Range: —40 ... +60 °C or —40 ... +140 °F Missing data: NaN |
| Air temperature | f32 |
Measured air temperature Range: —40 ... 60 °C or —40 ... +140 °F Missing data: NaN |
| Dew point temperature |
Dew point temperature Range: —40 ... +60 °C or —40 ... +140 °F Missing data: NaN As dew does not form in freezing conditions, dew point value is not relevant when it is below 0 °C (+32 °F). |
|
| Frost point temperature | f32 |
Dew / frost point temperature (dew point reported above freezing conditions, frost point reported in freezing conditions) Range: —40 ... +60 °C or —40 ... +140 °F Missing data: NaN In freezing conditions, instead of dew point, the relevant value for understanding the risk of frost (ice) formation is frost point |
| Relative humidity | f32 |
Measured relative humidity Range: 0 ... 100 %RH Missing data: NaN |
