Weather Measurement Concepts

Sylvia Knight from the Royal Meteorological Society provides an overview of various weather measurement techniques useful for independent investigations. The video covers tools and methods for measuring temperature, humidity, rainfall, air pressure, light, and wind speed. It includes practical tips on using digital thermometers, rain gauges, and anemometers, as well as advice on calibrating instruments and ensuring accurate readings. The video also highlights the availability of weather instruments for loan from the Royal Meteorological Society.
