Abstract
Interested in studying the message and a way to calculate and estimate the solar radiation vehicles to places where there are no measurements here were discussed and three types of models have been tested the results with observations corresponding
interested in research and also estimate the radiation spectrum of direct and dispersed and the total horizontal surface of Cairo was the adoption of model Bird to estimate the radiation Vehicles in periods of Nubian length of 0.01 micron
also been studying the radiative forcing of the aerosol to investigate its role in the heating and cooling of the atmosphere in addition to its impact on the climate based on its physical properties and chemical behavior and to determine the impact of using the global data
It was concluded that a doubling of the concentration of CO carbon dioxide in the atmosphere will cause global temperature increase by 1.6 degrees Celsius.
also been drawn to a mathematical estimate the effort of evaporation from water surfaces and plants on the basis of equation Penman.
