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 book The Weather Observer’s Handbook (published by Cambridge University Press), 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
When choosing a weather station, or components of a weather station, decide firstly what the equipment will mainly be used for: some potential uses may not be immediately obvious. Once that is clear, review the relevant decision-making factors as outlined in The Weather Observer's Handbook, Chapter 2, then prioritize them against your requirements.
The units of atmospheric pressure are hectopascals (hPa) – a hectopascal is numerically identical to the more familiar millibar. Inches of mercury are still used for some public weather communications within the United States – one inch of mercury is 33.86 hPa.
Earth temperatures are normally quoted for a morning observation hour, although hourly values can easily be derived from logged electrical sensors. Hourly values provide useful insights into diurnal temperature variations below the earth’s surface.
Grass temperatures should be sampled and logged at the same interval as used for air temperatures; for earth temperatures, particularly at depth, an hourly or even once-daily logging interval may be sufficient.
Barometric pressure is the easiest of all of the weather elements to measure, and even basic weather stations or household aneroid barometers can provide reasonably accurate readings. It is also the only weather element that can be observed indoors, making a barometer or barograph – analogue or digital – an ideal instrument for apartment dwellers.
