Data logging

        In computing, the process, usually automatic, of capturing and recording a sequence of values for later processing and analysis by computer. For example, the level in a water-storage tank might be automatically logged every hour over a seven-day period, so that a computer could produce an analysis of water use.

        Weather logging        Observations can be collected not only from land stations, but also from weather ships, aircraft, and self-recording and automatic transmitting stations, such as the radiosonde. Radar may be used to map clouds and storms. Satellites have played an important role in televising pictures of global cloud distribution.

        As well as supplying reports for the media, the Meteorological Office in Bracknell, near London, does specialist work for industry, agriculture, and transport. Kew is the main meteorological observatory in the British Isles, but other observatories are at Eskdalemuir in the southern uplands of Scotland, Lerwick in the Shetlands, and Valentia in SW Ireland. Climatic information from British climatological reporting stations is published in the Monthly Weather Report, and periodically in tables of averages and frequencies.
