Research on microwave remote sensing of atmospheric water

Ground based observation of atmospheric emission in the microwave band may be used to measure atmospheric parameters such as temperature profile or concentration of water vapour liquid water, ozone and other atmospheric trace gases. By using atmospheric noise reception of 1.35 cm water vapour absorption band and 8 mm window region, we could obtain the atmospheric total water vapour content and liquid water content in cloud. In this paper by way of calculating atmospheric radiation brightness temperature at four microwave bands it could be demonstrated that the 3 mm band have more sensitive to the water vapour content and liquid water content than 1.35 cm and 8 mm bands especially for the water vapour content in clear sky. Consequently developing 3 mm band radiometry is advantageous to remote sensing atmospheric water. Continuous measurements with high accuracy are important in determining forecasting on the mesoscale and heat balance in climatology.EI03354-3583
