Microbarometer

Micro- barometers are extremely sensitive barometer for measuring air pressure at a resolution in the range of microbars ( μbar ) - or in the area Pascal ( Pa). Conventional barometer usually have a millibar (mbar) - or Hektopascalteilung (hPa ).

With the help of micro- barometers compliance with internationally agreed Comprehensive Nuclear Test Ban Treaty ( CTBT ) is monitored at several locations around the world, so in Germany. The corresponding pressure waves from atomic bomb tests can travel long distances. By analyzing simultaneously recorded in several places print data to the explosion and explosion strength can be calculated.

Would a micro barometer as an altimeter with absolutely constant air pressure ( even without Mikrobarome, ie ideal condition) is used, this height differences would show almost the exact centimeter.
