Hello,

I want to start taking readings of rainfall, min/max temperature and also
air pressure. But I have a few questions and would be really grateful if
someone would answer them for me.

1. Should a barometer be set to read the exact air pressure where it is set
or should it be adjusted to mean sea level where it is?

2. What are the cheapest, most accurate rain gauges and min/max thermometers
available to buy on the internet?

3. What are the Met. Office standards for rain gauges in terms of
dimensions?

4. How do you know whether a thermometer (or rain gauge for that matter) are
calibrated to provide an accurate comparison with official station records?

At the moment I'm looking at www.ukweathershop.co.uk but if someone can
suggest another place, that would be great. Are all tipping bucket rain
gauges digitized?

Thanks in advance,

Jeremy
