Airport weather forecast TAF
Aerodrome forecasts for international airports and regional aerodromes are issued in the TAF (Terminal Aerodrome Forecast) code format. For flight preparation, TAFs serve as the internationally standardised aeronautical meteorological forecast needed to decide on the meteorological usability of an aerodrome as destination or alternate aerodrome during a certain time period. TAFs are quality-controlled, monitored forecasts that are created based on con- tinuous weather observation. They are only produced if a sufficient number of observation data of satisfying quality is available.
Visibility is a measure of the horizontal opacity of the atmosphere at the point of observation and is expressed in terms of the horizontal distance at which a person should be able to see and identify: in the daytime, a prominent dark object against the sky at the horizon; at night, a known, preferably unfocused, moderately intense light source.
Surface Visibility is the greatest visibility, taken at the surface, equaled or exceeded throughout at least half the horizon circle.
The true direction from which the wind is blowing at a given location (i.e., wind blowing from the north to the south is a north wind). It is normally measured in tens of degrees from 10 degrees clockwise through 360 degrees. North is 360 degrees. A wind direction of 0 degrees is only used when wind is calm.
Wind roses typically use 16 cardinal directions, such as north (N), NNE, NE, etc., although they may be subdivided into as many as 32 directions. In terms of angle measurement in degrees, North corresponds to 0°/360°, East to 90°, South to 180° and West to 270°.

The unit of measure for cloud cover is the Okta. Cloud cover is measured on an eight point scale, 0 Oktas being clear sky , one Octa being 1/8 of the sky covered in cloud, and so on up to 8 Oktas - completely overcast.
