Snow and Frost API Parameters
Frost & Thaw DepthThe frost and thaw depth parameters indicate the depth to which the earth has frozen and the depth to which the earth has thawed in centimeters based on information from different soil layers.

Soil FrostThis parameter provides the probability in percent for the occurrence of soil frost based on surface and ground temperatures.

Amount of Snow MeltFollowing parameter returns the snow height that melted within the given interval, i.e. the difference in snow height in cm:
Following paramter returns the height of the water equivalent of the melted snow in mm (that is the same as l/m²). Please note that it is not the height of the snow cover in mm.

Snowfall ProbabilityThis index provides the probability in percent for precipitation to occur in the form of snow.

Snow DriftThe snow drift parameter describes how strong snow is carried over the surface due to environmental factors such as wind speed. The index ranges from 0 to 6 with higher values indicating a higher amount of fresh snow being transported because of high wind speeds.
- In early February 2021, many train connections in the northern half of Germany had been cancelled due to strong snow drifts over train tracks: https://api.meteomatics.com/2021-02-07T12:00:00Z/snow_drift:idx/54,8.5_51,14.9:0.025,0.025/html_map
Rime ProbabilityThis index describes the probability of rime occurrence.
- The occurrence of rime has a higher probability from late autumn to early spring: https://api.meteomatics.com/2021-02-09T07:50:00Z/prob_rime:p/53.5,7.5_51,11.5:0.01,0.01/html_map
