Transmissometer records at Schiphol-Airport, Amsterdam have been analyzed to show the frequencies of visibility changes, in periods between 1 and 16 minutes, on occasions that the visibility is below 1000 metres for at least 30 minutes. Tables are presented for the frequencies of visibility changes in shallow and in deep fog, both for increasing and decreasing visibilities, with an initial visibility in the range of 60–1000 metres (the lower limit of this range is connected with the length of the transmissometer-baseline in use).
In deep fog the probability of a visibility change surpassing 25 percent is about 1 percent after 1 minute and 20 percent after 16 minutes if the initial visibility is between 100 and 200 metres. The corresponding figures in shallow fog are 7 and 55 percent. If the initial visibility is between 200 and 400 metres, the corresponding figures in deep fog are 5 and 45 percent and in shallow fog 26 and 84 percent.
