Whether and climate Weather is the condition of the atmosphere in terms of temperature, humidity, winds and precipitation Climate is defined as the average weather over various time periods ranging from a few weeks to decades to geological timescales Whether and climate are ultimately determined by location, topography, and the exchange of radiant energy between the Sun, Earth, and space

Air quality and particles Epidemiological(流行病学) evidence associates atmospheric particles with diseases and mortality Particles penetrate the lungs, blocking and irritating aIr passages. Particles themselves could exert toxic effects. ( toxic substances present in the particles [polycyclic Aromatic Hydrocarbons are examples of toxic substances in aerosols.]

Good Ozone and Bad Ozone Stratospheric ozone protect lives on Earth from harmful effects of UV radiation. .Iropospheric ozone: Causing respiratory distress and eye irritation Destroying plants Producing cracks in rubber Ozone is a strong oxidant, reacts with molecules containing C=C double bonds, forming epoxides

Water vapor in the air The volume of Water vapor is variable, depending on temperature, precipitation, rate of evaporation and other factors at a particular location The percentage of water vapor ranges from 0.1- 5%. Generally it is 1-3%(the 3rd most abundant constituents in the air)
