Estimated class — discuss.
I have known of this site for several years and that it is unusual in being surrounded by a hedge. In the context of trying to classify according to WMO 2010 this raises a question of interpretation. See continuation below.
WMO 2010 make no reference to a meteorological site enclosure or fence yet these are common for security or site integrity reasons: such as keeping sheep or tractors away from the instrument.
For Class 1 and 2 it states
“Flat, horizontal land, surrounded by an open space, slope less than 1/3 (19°);”
“Flat, horizontal land, surrounded by an open space, slope inclination less than 1/3 (19°);”
Class 3 and above omit this requirement.
In the case of Liscombe the hedge at 10 metres could be taken as a wall, Class 3 or does not exist, Class 1.
Any opinions or ideas?
