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
Weather knows no boundaries. The inherent interest in taking weather observations are greatly enhanced by exchanging and comparing observations with others locally, nationally or internationally.
It is advisable to check and test all sensor / datalogger / software and communications thoroughly, over a period of at least a few days, before permanent hardware installation or embarking on any long-term data collection.
The choice of datalogger and automatic weather station (AWS) software is crucial to the effective operation of any AWS. Its specification will define the capabilities (or limitations) of the AWS, and the choice of unit should be given at least as much consideration as the choice of sensors.
Where accurate air pressure records are required, the observed barometer reading needs to be adjusted to a standard level, usually mean sea level (MSL), because air pressure decreases rapidly with altitude. A variety of approaches exist to correct or ‘set’ a barometer to mean sea level: four are described in The Weather Observer's Handbook The choice of method depends upon accuracy sought (and the accuracy of the sensor) and height above sea level. Downloadable Excel spreadsheets are available on this site to simplify the production of site-specific sea level correction tables where desired.
Wind is a vector quantity – it has both direction and speed. Wind direction refers to where the wind is coming from. A wind vane needs to be accurately aligned to true north, which is slightly different to the magnetic north shown by a magnetic compass.
