Visibility data
-
Visibility data displayed under flying is usually between 30-40km, what altitude is this taken at? And is there any way to display surface visibility, typically ~8NM (see below image from NOAA NDBC)
-
Forecasting surface visibility by a weather model is very-very dificult.
I don't know why the ECMWF "dared" to publish that data.
I count it as experimental.
-
@meteo-GR No I am preparing "pilotgrams" based on this and the data does not look so bad.
