Document Summary
About 50% of the globe is covered by clouds. Sources of energy responsible for our climate. The effect of atmospheric constituents on the state of the earth/atmosphere system. How can it change by adding man-made materials. Temperature reported to public is measure at about 2m level in a protected and ventilated screen. Temperature change because of surroundings or climate change. Zero level: 273, 0, 32 (no motion) The absolute zero temperature is the temperature at which the molecules do not move at all. The kelvin scale is a new temperature scale that has its zero value. Bimetallic strip bends because the two metals expand differently. The extent of the bending depends on temperature. The levers amplify the deformation and allow the arm to record changes in temperature. Temperatures can also be measured remotely using infrared sensors (radiometers) Measures temperature, humidity and wind above the earth"s surface.
