In most countries, atomic clocks are used as the benchmark for keeping accurate time to a near infinitesimal degree. Governments broadcast the exact time over radio, and instruments can pick this up and calibrate their internal clocks. Many modern weather stations make use of this accuracy, ensuring that weather enthusiasts can make exceptionally readings. While these are called, 'atomic clocks,' they are not in themselves atomic, and merely contain a receiver to pick up the broadcasts.
Discount atomic clock weather stations are available online, and allow you to monitor local weather conditions to a high degree of accuracy, perfect if you are a gardener, angler or farmer. Reputable companies, such as Davis and Oregon Scientific provide instruments that are accurate, durable, and competitively priced.
