Rainfall estimation by weather radar
No full textKnowledge of the spatial and temporal variability of rainfall over a wide range of scales is required in a variety of disciplines. Examples range from hydrology, soil erosion, and cloud and precipitation physics to the design and operation of water management, telecommunication, and atmospheric remote sensing systems. As a result of the gradual development of radar technology over the past 70 years, ground-based weather radar represents now an established tool for quantitative rainfall measurement at a space-time resolution of typically 1 km2 and 5 min, over a wide range of spatial and temporal scales. This chapter provides an outline of the principles of precipitation estimation by means of weather radar, with coverage of the main techniques for weather radar observation and of the methods used to generate rainfall products starting from weather radar observables
