# Climatic Variables

The aggregated monthly statistics for each climatic variable

Here the available via the API climatic variables are presented and described. The detailed reference for the API can be found here.

## cloud cover

The average and standard deviation numbers of hours with clouds over the period 00h-24h local time divided by 24 hours.

## consecutive dry days

The average and standard deviation numbers of consecutive days with less than 1 mm rainfall height per month

## consecutive frost days

The average and standard deviation numbers of consecutive days with less than 0 degrees per month.

## consecutive summer days

The average and standard deviation numbers of consecutive days with maximum temperature more than 25 degrees Celsius per month.

## consecutive wet days

The average and standard deviation numbers of consecutive days with more than 1 mm precipitation height per month

## dew point temperature

The average and standard deviation dew point temperature at a height of 2 meters above the surface over the period 00h-24h local time. The dew point is the temperature to which air must be cooled to become saturated with water vapor. In combination with the air temperature it is used to assess relative humidity.

## frost days

The average and standard deviation numbers of days where TN < 0 ℃ is counted

## heating days

The average and standard deviation heating degree days are defined as the sum of T1 - TG, where only values TG < T2 are considered. If T1 and T2 are omitted, a temperature of 17℃ is used for both parameters.

## ice days

The average and standard deviation numbers of days with less than 0 Celsius temperature

## maximum temperature

The average and standard deviation "Maximum Temperature" of air in Kelvin at a height of 2 meters above the surface.

## mean temperature

The average "Mean Temperature" of air in Kelvin at a height of 2 meters above the surface.

## minimum temperature

The average and standard deviation "Minimum Temperature" of air in Kelvin at a height of 2 meters above the surface.

## precipitation days (10mm)

The average and standard deviation numbers of days where the daily precipitation flux is at least 10 mm is counted.

## precipitation days (20mm)

The average and standard deviation numbers of days where the daily precipitation flux is at least 20 mm is counted.

## precipitation days (50mm)

The average and standard deviation numbers of days where the daily precipitation flux is at least 50 mm is counted.

## precipitation flux

## snow thickness

## solar radiation

The average and standard deviation solar radiation flux. Total amount of energy provided by solar radiation at the surface over the period 00-24h local time per unit area and time.

## volumetric soil moisture
