Weather variables information

  • Temperature (2m) and relative humidity (2m): Comparable to measurements at 2 meters above ground.
  • Growing degree days (2m): Absolute temperature difference between a base (e.g. 10°C) and limit (30°C). Calculated on hourly data instead of daily minimum and maximum.
  • Pressure: Atmospheric air pressure reduced to mean sea level as most commonly used for weather reports. The local pressure varies with altitude. Locations at higher elevation have a lower local atmospheric pressure.
  • Precipitation amount: Total precipitation amount including rain, convective precipitation and snow. 1mm at 10:00 is comparable to a rain-gauge measurement from 9:00-10:00.
  • Snowfall amount: Fraction of total precipitation that falls down as snow and is converted to cm instead of mm.
  • Total cloud cover: Percentage of the sky that is covered with clouds: 50% means half of the sky is covered. 0-25% clear sky, 25-50% partly cloudy, 50-85% mostly cloudy and above 85% overcast.
  • Low, mid and high cloud cover: Cloud cover at different altitudes. High clouds (8-15 km) like cirrus are less significant for total cloud cover than low (below 4 km) like stratus, cumulus and fog or mid clouds (4-8 km) like alto cumulus and alto stratus.
  • Solar radiation: Global radiation (diffuse and direct) on a horizontal plane given in Watt per square meter.
  • Wind speed: Hourly average wind speeds at given altitude levels "10 and 80 meters above ground" or pressure level "900 hPa". Units can be selected.
  • Wind direction: Wind direction in degrees seamless from 0° (wind blowing from north), 90° (east wind), 180° (south wind) and 270° (west wind).
  • Wind gusts: Short term wind speed turbulence in an hour. Gusts indicate the level of turbulence as such they could be lower than regular wind speeds.

Distribution

Accumulate each data-series. Very common for growing degree days and precipitation amount.

Units

Parameter for growing degree days

Adjust base and limit parameter for growing degree calculation. A limit-value lower than base, calculates the temperature cold sum.
