Available Parameters

Yearly Accumulated Day Counts

These parameters represent the number of days that fulfilled a certain condition starting from January 1st of the queried year.

 

Temperature Dependent

Below is an overview of all temperature dependent parameters:

Vegetation Days | Heating Days | Desert Days | Hot Days | Summer Days | Tropical Nights | Frost Days | Ice Days

Every parameter is now explained in more detail:

 

Vegetation Days

This parameter returns the number of vegetation days (days on which the mean temperature was above 5 degrees C) since 1st of January.

vegetation_days:d

Examples

 

Heating Days

This parameter returns the number of heating days (days for which the 24h-mean is less than 15°C, or the number of days buildings need to be heated) since 1st of January.

heating_days:d

 

Heating Degree Days

Heating degree day (HDD) is a measurement designed to quantify the demand for energy needed to heat a building. This parameter returns the accumulated temperature difference to a configurable base temperature, if the temperature is below that base temperature, since 1st of January.

heating_degree_days:hdd

heating_degree_days_base_<base_temperature>:hdd

Available base temperatures: countinuous from 0°C to 30°C. Default is 15°C.

Desert Days / Extremely Hot Days

This parameter returns the number of extremely hot days (days on which the maximum temperature at 2m exceeds 35 degrees C) since 1st of January.

desert_days:d

Examples

 

Hot Days

This parameter returns the number of hot days (days for which the 24-hour maximum temperature was greater than 30°C) since 1st of January.

hot_days:d

Examples

 

Summer Days

This parameter returns the number of summer days (days for which the 24-hour maximum temperature was greater than 25°C) since 1st of January.

summer_days:d

Examples

 

Tropical Nights

This parameter returns the number of tropical nights (days for which the 24-hour minimum temperature was greater than 20°C) since 1st of January.

tropical_nights:d

Examples

 

Frost Days

This parameter returns the number of frost days (days on which some frost occurred) since 1st of January.

frost_days:d

Examples

 

Ice Days

This parameter returns the number of ice days (days for which the 24-hour maximum temperature was less than 0°C) since 1st of January.

ice_days:d

Examples

 

Precipitation Dependent

 

Rain Days

This parameter returns the number of rain days (days on which at least 0.1 mm of rain fell) since 1st of January.

rain_days:d

Examples

 

Heavy Rain Days

heavy_rain_days:d

This parameter returns the number of heavy rain days (days for which the precipitation sum was greater than 10mm) since 1st of January.

Examples

 

Dry Days

This parameter returns the number of dry days since 1st of January.

dry_days:d

Examples
