The invention relates to a method for producing total water vapor and layered water vapor products of a stationary meteorological satellite, which comprises the following steps of: (1) defining and initializing variables and constants, and reading imager data and auxiliary data; (2) circulating pixel by pixel and atmospheric layer by atmospheric layer; (3) judging whether the atmospheric temperature and pressure intensity observed on the earth surface are effective or not, sampling the atmospheric temperature and humidity profile data to a new atmospheric layer, and searching an earth surface air pressure layer; (4) physically inverting an atmospheric temperature and humidity profile; (5) calculating the layered water vapor content and the total atmosphere water vapor content according to the humidity profile; and (6) outputting layered water vapor content and atmosphere total water vapor content results. According to the invention, the total amount of water vapor in a clear sky with high spatial resolution a
