The wind indicator for a weather observation receives the measured value from an anemometer. Where is this instrument placed and at what height?
10m above the runway.
On an infrared meteorological satellite image, a large, bright-white area is clearly noted. On a visible satellite image of the same area, at the same time, a translucent whitish layer is observed. The most likely conclusion from both images is that there is..
A thin layer of cirrostratus
According to ICAO, vertical visibility should be reported:
(1) when expressed in feet, in steps of 100 ft up to 2 000 ft;
(2) when expressed in metres, in steps 30 m up to 600 m.
Both correct
Why are Gridded forecasts good?
Visualise hazrds.
At larger aerodromes, the reported surface wind is measured by an anemometer at a height of x m and averaged over x minutes for the ATIS and the aerodrome controller, but averaged over x minutes for the METAR.
10m 2 minutes 10 minutes
Decode the following message:

Runway Visual Range (RVR) is usually better then blank visibility.
