parameters

name	original name	description	unit
temperature_air_mean_2m	mean(air_temperature P1M)	Monthly mean temperature. The mean is an arithmetic mean of daily values.	degree_celsius
temperature_air_max_2m	max(air_temperature P1M)	Highest recorded air temperature per month	degree_celsius
temperature_air_min_2m	min(air_temperature P1M)	Lowest recorded air temperature per month	degree_celsius
temperature_dew_point_mean_2m	mean(dew_point_temperature P1M)	Monthly mean dew-point temperature. Dew-point temperature is the temperature at which the air, when cooled, will become saturated (and dew is formed).	degree_celsius
precipitation_height	sum(precipitation_amount P1M)	Monthly precipitation sum.	millimeter
wind_speed	mean(wind_speed P1M)	Monthly mean wind speed of hourly observations (00, 01, 02,…, 23 UTC). If hourly observations do not exist then the main observation times are used (06, 12, 18 UTC and also 00 UTC where available).	meter_per_second
wind_speed_rolling_mean_max	max(wind_speed P1M)	Monthly maximum mean wind speed of hourly observations (00, 01, 02,…, 23 UTC). If hourly observations do not exist then the main observation times are used (06, 12, 18 UTC and also 00 UTC where available).	meter_per_second
humidity	mean(relative_humidity P1M)	Monthly mean relative humidity.	percent
pressure_air_sea_level	mean(air_pressure_at_sea_level P1M)	Monthly mean air pressure reduced to sea level. The parameter is usually called QFF in aviation and shows the measured air pressure reduced to mean sea level by applying actual atmospheric conditions.	hectopascal
pressure_air_site	mean(surface_air_pressure P1M)	Monthly mean air pressure at the station. The parameter is usually called QFE in aviation and shows the measured air pressure reduced to the reference height of the station.	hectopascal
cloud_cover_total	mean(cloud_area_fraction P1M)	Monthly mean cloud cover. The mean is an arithmetic mean of three daily observations (06, 12 and 18 UTC).	one_eighth
snow_depth	mean(surface_snow_thickness P1M)	Monthly mean snow depth. The mean value is an arithmetic mean of daily values.	centimeter
sunshine_duration	sum(duration_of_sunshine P1M)	Number of hours of sunshine over the last month.	second
