Robust data loggers monitor environmental conditions over time to provide readings for comparison with an automatic weather station, and for submission to the Met Office and the Climatologist Observers Link.
David King is an amateur climatologist who runs the website
www.weatherwithouttechnology.co.uk The aim of the
website is to inform and demonstrate that you do not need
technology to predict weather at least three months and in some
cases six months ahead, with a reasonable (85/90% consistent)
accuracy. The site is used by numerous businesses, organisations,
weather amateurs and professionals, as well as the national
David's methods are a combination of using the phases of the
moon with ancient tried, tested and reliable moon weather data; the
tides; nature's signs, birds, animals, flora and fauna; some 5000
tried tested and reliable sayings and much local data going back 40
years. This combines into a tried and tested methodology to produce
weather patterns/predictions months before they occur. David aims
to demonstrate that while modern technology is invaluable for short
term forecasting (day to day weather), no computer system will be
able to replicate or predict what nature can tell us.
David is using a Tinytag Plus 2 data
logger and a Tinytag
Thermohygrometer to record temperature and relative humidity.
Both loggers are contained with a standard Stevenson Screen and are
used to monitor on a permanent 24 hour basis, working as a back-up
to, and a verification of, all such readings taken from a DAVIS VP2
automatic weather station that is positioned elsewhere in the
garden. They also provide back-up for the certified and tested
sheathed Max, Min and standard thermometers also used with the same
The data is used for daily weather submissions to the Met Office
Weather Observations Website (WOW), and is submitted monthly to the
Climatologist Observers Link (COL), an organisation that has been
publishing monthly reports of the weather for over 40 years. The
data is also referred to when special requests are made for weather
data for a particular day or period (insurance companies find such
specialised data vital).
David finds the Tinytags to be reliable, robust and accurate. He
comments, "They are exactly what I require for my use, the battery
life is excellent, they are virtually fail-safe too. I would not
now be without them!"
The Royal Meteorological Society (RmetS) has purchased Tinytags
and these are loaned to members for usage.
