  Description Methods of calculating
     
Tmax = maximum air temperature automatically calculated from all single values1
Tm = average air temperature automatically calculated from all single values 
Tmin = minimum temperature automatically calculated from all single values
Emin = min. temperature 5 cm agl2 manually calculated from hourly measurements
RH = average relative humidity manually calculated from values at SYNOP times 3
PPP = sea-level pressure manually calculated from values at SYNOP times
WW = weather conditions4 continuous observation
RR = amount of precipitation manual measurement at 7 am and 7 pm CET
SH = snow depth manual measurement at 7 am CET
Vmax = maximum wind speed automatically calculated from all single values
Vdir = prevailing wind direction automatically calculated from all single values
Data = available datasets manually calculated from hourly records5
     
  Additional Abbreviations  
     
RR24h = maximum of RR within 24 h  
SHmax = maximum of snow-depth  
pmax = highest pressure at sea level  
pmin = lowest pressure at sea level  
Vm = Vmax averaged  


1At undisturbed operation, the system records a complete set of data every 10 seconds, i.e. 8,640 datasets a day. 
2 agl = above ground level
3 Synop times are 1.00, 4.00, 7.00, 10.00, 13.00, 16.00, 19.00, 22.00 CET

4 SYNOP code:
0 = Cloud covering 1/2 or less of the sky throughout the appropriate periode
1 = Cloud covering periodically more than 1/2 and less than 1/2 of the sky
2 = Cloud covering more than 1/2 of the sky throughout the periode
3 = Sand storm, dust storm or blowing snow
4 = Fog or thick haze
5 = Drizzle
6 = Rain
7 = Snow, or rain and snow mixed
8 = Shower(s)
9 = Thunderstorms with or without precipitation
If more than one form of weather is observed, the highest applicable code figure is selected.

5Availability of data is defined as the quotient of the number of recorded datasets and the maximum number of datasets possible.



Climatological threshold days:

 
  Definition  
NT = Tmax 30.0°C or higher  
NS = Tmax 25.0°C or higher  
NE = Tmax 0.0°C or below  
NF = Tmin 0.0°C or below  
NBFT = Emin 0.0°C or below  
NSCH = Day with snow cover of at leat 1 cm in depth at 7 am
