Precipitation product integration method of geostationary meteorological satellite and polar-orbiting meteorological satellite

Abstract

The invention discloses a precipitation product integration method of a geostationary meteorological satellite and a polar-orbiting meteorological satellite. A Lagrange integration algorithm is adopted, infrared observation information of the geostationary meteorological satellite is used for computing infrared cold cloud moving vector to provide a constraint condition for the development of polar-orbiting meteorological satellite microwave precipitation, and therefore the integration of the infrared observing information of the geostationary meteorological satellite and the polar-orbiting meteorological satellite microwave precipitation is achieved. According to the method, the respective advantages of the geostationary meteorological satellite and the polar-orbiting meteorological satellite can be fully achieved through the integral application of the geostationary meteorological satellite and the polar-orbiting meteorological satellite.

Description

technical field [0001] The invention relates to the field of satellite product integration, in particular a method for integrating precipitation products of geostationary meteorological satellites and polar orbiting meteorological satellites is invented. Background technique [0002] Since the Fengyun Meteorological Satellite was included in the global Earth observation satellite sequence by the World Meteorological Organization and became an important member of the Global Earth Observation System, China has launched three more geostationary meteorological satellites, FY-2D, FY-2E, and FY-2F, and FY -3A, FY-3B, and FY-3C are three polar-orbiting meteorological satellites. These satellites have played an important role in weather forecasting, typhoon monitoring, and flood monitoring. They also have their own advantages in precipitation inversion. [0003] FY-2 series geostationary meteorological satellites have high spatial-temporal resolution for earth observation, and can i...
