Temperature is a physical property of a system that underlies the common notions of hot and cold; something that is hotter generally has the greater temperature. Temperature is one of the principal parameters of thermodynamics. On the microscopic scale, temperature is defined as simply the average energy of microscopic motions of a single particle in the system per degree of freedom. On the bulk scale, common to non-scientists, temperature is defined as that unique physical property that is shared between two otherwise entirely unlike things that happen to be in thermal equilibrium with each other (meaning, no net heat energy is exchanged between them). For a solid, these microscopic motions are principally the vibrations of the constituent atoms about their sites in the solid. For an ideal monatomic gas, the microscopic motions are the translational motions of the constituent gas particles. For multiatomic gas vibrational and rotational motion should be included too.
Temperature is measured with thermometers that may be calibrated to a variety of temperature scales. In most of the world (except for the United States, Jamaica, and a few other countries), the Celsius scale is used for most temperature measuring purposes. The entire scientific world (the U.S. included) measures temperature using the Celsius scale and thermodynamic temperature using the Kelvin scale, which is just the Celsius scale shifted downwards so that 0 K[1]= -273.15 °C, or absolute zero. Many engineering fields in the U.S., especially high-tech ones, also use the Kelvin and Celsius scales. The bulk of the U.S. however, (its lay people, industry, popular meteorology, and government) relies upon the Fahrenheit scale. Other engineering fields in the U.S. also rely upon the Rankine scale (a shifted Fahrenheit scale) when working in thermodynamic-related disciplines such as combustion.

Temperature is defined as the condition which determines the flow of heat from one substance to another.Temperature is different from heat. Heat is a form of energy whereas temperature is a factor which effects the availability of this energy.Therefore,the temperature is also known as the degree of hotness of a body.There are various scales for measuring the temperature-The Farenheit,Celcius and Absolute.The measuring instrument in any of these scales is known as thermometer.
For meterorological purposes we need knowledge of temperature of the surface of the earth(land or sea) as well as the atmospheric temperature.
As the atmosphere is composed of air,we have to take the free air into consideration and the temperature measured thus is known as the 'air temperature'.
