This site provides useful practical information related to global and national weather observing practices and instruments, including independent equipment reviews.
You will find much of the background in my new book The Weather Observer’s Handbook (Cambridge University Press, 2012), details of which can also be found on this site, together with useful links and downloads.

A nation obsessed with the weather? Yes, certainly, but which nation?
Tip of The Day
Generally speaking, the best exposure to the wind will be obtained by exposing both anemometer and wind vane in as open a position as possible, as high as possible, commensurate with both safety and accessibility for installation and maintenance. The necessarily elevated exposure will increase the vulnerability of the instruments to extreme weather conditions, particularly snow or ice, lightning and of course high winds. Great care should be taken in installation and cabling to minimize the potential for subsequent weather-related reliability issues.
Never take risks with personal safety when installing any weather sensors at height.
Choosing a weather station can be complex and a number of important factors may not be immediately obvious to the first-time purchaser. Deciding a few months down the line that the unit purchased is unsuitable and difficult to use (or simply does not do what you want it to) is likely to prove an expensive mistake, as very few entry-level and budget systems can be upgraded or expanded.
To obtain records of the timing and intensity of rainfall, one or more recording raingauges are often sited alongside the manual raingauge. The record from the manual gauge should be taken as the standard period total and sub-daily records (hourly totals, for instance) taken from the recording gauge adjusted to agree with the daily total taken from the manual gauge. The use of standalone recording gauges is not recommended when accurate or comparable rainfall totals are required.
Site and exposure. Site refers to ‘the area or enclosure where the instruments are exposed’, while exposure refers to ‘the manner in which the sensor or sensor housing is exposed to the weather element it is measuring’.
