Abstract: The present disclosure provides a method, system and apparatus for correcting satellite observation data. By acquiring microwave radiometer (MWR) movement observation data of a radiosonde observation limited sounding area, correcting the MWR movement observation data based on corresponding radiosonde observation data, and correcting satellite observation data based on the radiosonde observation data and corrected MWR movement observation data, the present disclosure corrects the satellite observation data of the radiosonde observation limited detection area, reduces an error of the satellite observation data, and makes the satellite observation data more accurate.

Abstract: A bearing-equipped resin pulley is equipped with a metal ring-shaped member (21) having an overall circular shape and pressed into the outer-diameter surface (3c) of an outer race (3), and has a resin pulley (15) integrally formed around the metal ring-shaped member (21). The metal ring-shaped member (21) comprises a cylindrical engaging part (23) for engaging the outer-diameter surface (3c) of the outer race (3) by being pressed therein, and a disc part (29) integrally formed in an upright manner in the perpendicular direction from the engaging part (23). Furthermore, the disc part (29) is provided with a plurality of holes (31) formed in the axial direction of the bearing (1) and arranged in the circumferential direction. As a result, it is possible to improve creep resistance even under harsh conditions of high rotation speed and high belt load.
