An atomic resonance frequency standard is used in Atomic clocks. It is a compact weather instrument that offers complete weather forecasting along with time and date controlled by radio. Atomic weather clocks features barometer based weather forecasting.

The atomic clock automatically coordinates itself with the US Commerce Department (Colorado) maintained “cesium atom-clock”. Atomic weather clock adjusts itself accordingly after receiving radio signals from the cesium atom-clock located in Colorado. This procedure is repeated several times each day. The adjustment is done to spit second accuracy that reach up to 4 billionths of a second. The signal range is approximately 3,000 miles. The atomic clock does not stop working even when radio signals are not received properly due to any kind of atmospheric condition.

These Atomic weather clocks are very useful for the people who have any kind of business deals in remote area that is directly related and depends on the weather condition. These Atomic weather clocks not only displays time but also offers moon phase display, measurement of indoor and outdoor humidity and even a 24 hour barometric history chart.
