Question

How should cloud height and visibility values be reported when they are halfway or less between two reportable values, according to the provided information?

Answer 1

Cloud height and visibility values that fall halfway or less between two reportable values should be rounded down to the lower standard value for reporting purposes.

Step-by-step explanation:

When reporting cloud height and visibility values that fall halfway or less between two reportable values, the convention is to report the next lowest standard value. For instance, if the cloud height is between 1800 meters and 2000 meters, and the observed height is 1900 meters or lower, then you report the cloud height as 1800 meters. The same principle applies to visibility: if visibility is halfway or less between two reportable distances, you should report the lower distance.
