Available Parameters

The following list shows the available parameters for operational and aircraft limit sets.

API_name	Description
wind_speed_mean_1h	The mean wind speed within a 1 hour interval. Available altitude range: 10-20000m
wind_direction_mean_1h	The mean wind direction within a 1 hour interval. Available altitude range: 10-20000m
wind_gust_1h	The mean wind gusts within a 1 hour interval. Wind gust includes the mean wind. Available altitude range: 10-20000m
precip_1h	Accumulated precipitation within a 1 hour interval. The following categories are used to classify rainfall intensity: < 2.5 mm/h Light rain 2.5-7.6 mm/h Moderate rain > 7.6 mm/h Heavy rain
precip_prob_1h	Probability of rain within a 1 hour interval.
outside_air_temperature_mean_1h	The outside air temperature (OAT). Available altitude range: 2-20000m
cloud_cover_low_perc	Cloud coverage between 0-2 km above ground level. (0-100 %)
cloud_cover_medium_perc	Cloud coverage between 2-7 km above ground level. (0-100 %)
cloud_cover_high_perc	Cloud coverage between 7-10 km above ground level. (0-100 %)
cloud_cover_total	The total cloud coverage is the fraction of the sky covered by all the visible clouds. (0-100 %)
cloud_base	The cloud base gives the lowest altitude of the visible portion of a cloud.
cloud_ceiling	The cloud ceiling is defined as the height of the lowest cloud layer covering more than half of the sky. A value of -666 denotes that there is no ceiling. Still, clouds can be there, covering less than 50% of the sky. Refer to cloud base as parameter.
visibility	Visibility on ground.
dew_point_mean_1h	Dew point temperature. Available altitude range: 2-20000m
relative_humidity_mean_1h	Relative humidity within a 1 hour interval. Available altitude range: 2-20000m
lifted_index	The lifted index is the difference between the temperature of the environment and that of an air parcel lifted adiabatically to a given pressure height in the troposphere, usually 500 hPa which is an index for instability in the air mass. The atmosphere at the given height is stable for positive values of the lifted index and unstable for negative values. When the value falls below -2, thunderstorms are anticipated and for lower values, especially those below -6, severe weather is expected.
cape_index	The convective available potential energy index (CAPE index) is the amount of energy a parcel of air would have if lifted a certain distance vertically through the atmosphere. Any value greater than 0 J/kg indicates instability and an increasing probability of thunderstorms and hail.
thunderstorm_prob_1h	Probability of a thunderstorm to occur within a 1 hour interval. (0-100 %)
gust_factor	The gust factor is defined as the difference between the peak wind gust of a 1 hour interval and the mean wind speed in the same period of time. Available altitude range: 10-10000m
spread	Difference between outside air temperature and the dew point temperature. Available altitude range: 2-20000m
general_icing	Icing conditions were identified based on the analysis of temperature and relative humidity combinations. This method represents a conservative approach since no droplet size or cloud data was considered. At some points, this more conservative approach might lead to overestimations.
kp_index	The KP-index gives a quantification of the disturbance of the magnetic field of the earth. Sun storms can disrupt GNSS (GPS) signals causing GNSS receivers to give misleading or wrong information. NOAA provides data for the period of 7 days. The Kp index is a quasi-logarithmic local index ranging from 0 to 9: 0-4 quiet period, 4-5 mild activity 5-9, high intensity storm.
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. 0-0.2: No icing, 0.2-0.4: Traces of icing, 0.4-0.6: Light icing, 0.6-0.8: Moderate icing, 0.8-1: Heavy icing.
