Dew or Rime
This index gives you an idea whether dew or rime will occur. Dew or rime forms if the surface cools down quicker than the surrounding air, which causes condensation onto the surface at high relative humidities. Dew and rime are very sensitive to solar radiation and disappear quickly as the surface warms. Rime is the frozen version of dew.
0: neither dew nor rime, 1: dew, -1: rime
dew_or_rime:idxExamples:

Dew or rime forecast for the next two days along with the expected temperatures. On the 8th March, 2017, some dew was expected from 3 to 5 a.m. This was expected to be followed by some rime one hour later, when the temperature dropped significantly:

Icing Potential
Icing is absolutely critical in aviation and in-flight icing on planes are the cause of multiple near-accidents or even crashes. Consequently, it is crucial for aviation to have reliable icing forecasts predicting the expected occurrence of icing on different altitudes and allowing for early circumnavigation.

Planetary Boundary Layer Height
The planetary boundary layer (PBL) height is determined by identifying the height, where big wind direction changes, local minima of wind speed, local maxima of temperature, high temperature increases (inversion) or high potential temperature increases occur.
pbl_height:mExamples

The PBL height until the day after tomorrow:

Snow Line
The snow line parameter provides the height above which precipitation occurs in the form of snow. Should it be undeterminable, for example if it is below ground level, it returns -666.
snow_line:mExamples
-
The height of the snow line for the next 5 days:

Freezing Level
The freezing level parameter provides the altitude where the temperature equals 0 °C. If the freezing level is below ground, the return value is -666. In case of strong convection, the height of the freezing level correlates with the size of hail observed at the surface, since it determines the melting area for falling hail.

Stratospheric Polar Vortex (SPV): Wind speed
This index provides the average wind speed at 10, 50 or 200 hPa between 60°N and 90°N and thus indicates the strength of the stratospheric polar vortex during the polar winter.
The SPV index provides a measure of the circumpolar vortex strength and indirectly relates to a risk of cooling temperatures near the surface in the northern hemisphere, if decreasing below zero.
If the index becomes negative, the vortex disruption is such that a “split" or strong “displacement" is under way, possibly weakening the jet stream in the troposphere.
polar_vortex_<level>:msAvailable levels: 200hPa, 50hPa, 10hPa

Power line oscillation warning
Precipitation in the form of freezing rain or wet snow can freeze onto overland power lines. With the increase in diameter and mass come a bigger air resistance and a lower resonance frequency. Strong wind over a sufficient amount of time could then excite the conductors to oscillate near their resonance frequency (sometimes referred to as gallop) and thereby damage the lines and masts.
A power line oscillation warning for the past 24 hours can be queried with the following parameter:
power_line_oscillation_24h:idxThe warning is binary with 1 corresponding to a warning and 0 to an all clear. Not taken into account are things like constructional details of the power lines or the Joule heat emitted by active power lines.
Example

On March 24 2016, there was a power outage in Halton Hills due to galloping power lines, which is exemplified by the following time series:

Soaring Index
The soaring-index is used for an estimation of the thermal situation. It is useful for paraglider and other sport pilots. A higher soaring-index also shows a greater chance of showers and thunderstorms, as it is a measure of the lift caused by convective clouds. The soaring index is independent of altitude, as it is computed with variables in different altitudes.
| soaring conditions | soaring index range |
|---|---|
| poor | <-10 |
| moderate | -10 to 5 |
| good | 5 to 20 |
| excellent | >20 |

Leisure Indices
The leisure index combines different weather parameters and assesses if weather conditions are favorable for certain outdoor activities or not. The index ranges from 0 to 1, where 1 means that conditions are perfect for the queried activity at the queried point in time (i.e. the parameter is instantaneous).
The indices are based on a combination of precipitation, temperature, wind speed, wind gusts, humidity, sunshine duration, snow cover, visibility and fog.

Laundry Index
The laundry index describes how well laundry dries in the air. Values closer to 1 indicate that laundry will definitely dry outside, whereas values towards 0 correspond to laundry that will remain wet.

Cold Index
This index combines several weather parameters like temperature, wind speed, humidity and precipitation and assesses how favorable these weather conditions are for catching a cold. The index takes values from 1 to 100, where higher values indicate higher risks.

Probability for Snow Cover
Gives the probability for a location/region being covered by snow. The probability is determined by combining information about temperatures at different altitudes and precipitation predictions.

Index for Windshield Icing
Gives the probability for the occurrence of windshield icing for cars. This index combines information about temperature, humidity, wind speed and other parameters and yields a probability in the range of 0-100 %. In addition, it is possible to specify an inclination between 0° (flat) and 90° (vertical) of the windshield - the default value is 50°.
