The time period will be used for each year. Leap year data could be off by one day to preserve accumulated sums.

Raportul meteo sub formă de istoric are ca limită de evaluare ultimele 2 săptămâni. Pentru a obţine acces nelimitat începând cu anul 1985, această locaţie trebuie activată cu history+.

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

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

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.
