Weather variables information
Temperature (2m) and relative humidity (2m): Comparable to measurements at 2
meters above ground.
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.

Time zone
All data will use the selected timezone. There is no automatic switching
for daylight saving time. Data are either summer or winter-time. The current timezone is selected
automatically. We highly recommend GMT+00 for further processing.
Çözünürlük
Aggregate data to daily minimum, mean, maximum and summation in CSV
download. This simplifies further data analyses in external programs.

5° to 30°C Wheat, barley, rye, oats
8° to 30°C Sunflower, potato
10° to 30°C Maize, sorghum, rice, soybeans, tomato
