Table 1. Data types
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

1 Measurement accuracy is affected when layer thickness reaches a specified limit. For the limits, see MD30 datasheet.
