charts show the results from an automatic weather station,
located at Wyenot News HQ, specifically: Latitude:
51° 55' 15.5" North - Longitude: 002° 34' 40.9"
speeds should be accurate. The red line is average wind
speed. The green line is gust speed. The gauge is located
above our roof at TV aerial hight.
Measurements should be fairly accurate. Straight line =
no rain during that period. The device is reset to zero
every Sunday, as near as possible to midnight GMT.
Pressure: The barometer is also accurate and there are
two pressure readings. The red line is the actual reading
at 'Wyenot News'. We are however located 232 feet above
sea level and air pressure drops 1 hPa per 30 feet asl.
The green reading should be the sea level reading.
Our thermometer needs re-siting as, although it is
already protected from direct sunlight by a white reflective
shroud, it still seems to be affected and read a degree
or two high compared to the weather station during brief
periods of direct sunlight, to which that shield is subjected.
I will try to relocate the sensor as soon as I can get hold
of a proper housing.
Chill: This is a calculation of how hot or cold it felt,
taking the wind into consideration.
do not take these readings as Gospel. Although we are
the opposite side of town to Ross Weather Station, the readings
seem to compare favourably but I am no weather expert!
