The Data Logging Transceiver has been relocated into the roof space. As this also records the Inside Temperature the reading displayed is taht of the roof space and not the Main Club room.
About the display:-
Wind speed indicator: shows three values; the needle shows the current snapshot of the wind speed, as read from the weather station. The green arc shows the current ten-minute average wind speed, and the red arc shows the recent highest gust (in the last ten minutes). Wind direction indicator: shows the current snapshot of the wind speed, as read from the weather station, with a red pointer; it also shows the average wind direction over the last ten minutes, with a blue pointer. The third indicator: gives a visual summary of the relative wind strength and direction over last few hours; the lines drawn in each direction take into account the strength of the wind as well as the length of time it has been coming from that direction. Cloud base: The calculated cloud base; 1000 feet for every 4.4 degrees Fahrenheit difference between the temperature and the dew point. Thus CB [metres] = (((Surface Temp F - Dewpoint F)/4.4) * 1000)/3.28 Wind run: A measurement of how much wind has passed a given point in a period of time in a specific direction. A wind blowing at three miles per hour for an entire hour would give a wind run of three miles. Dew Point: is the temperature to which a measurement of air must be cooled at constant barometric pressure for water vapour to condense into water. The condensed water is called dew. The dew point is also known as a Saturation Point. When the dew point temperature falls below freezing it is often called the frost point, as the water vapour no longer creates dew but instead creates frost or hoarfrost by deposition
