MWHTS and MWTS-II fusion inversion sea surface air pressure method based on simulated brightness temperature

The invention discloses an MWHTS and MWTS-II fusion sea surface air pressure inversion method based on simulated brightness temperature. The method comprises the steps: establishing matching data setsof an atmosphere data set and MWHTS observation brightness temperature and MWTS-II observation brightness temperature respectively; constructing an artificial atmosphere data set based on the matching data set, inputting the artificial atmosphere data set into a radiation transmission model RTTOV to calculate simulated brightness temperatures of the MWHTS and the MWTS-II, and testing the sensitivity of the MWHTS and the MWTS-II to the sea surface air pressure; establishing an inversion channel combination of MWHTS and MWTS-II fusion inversion sea surface air pressure, taking the simulated brightness temperature of the inversion channel combination as input, taking the corresponding sea surface air pressure as output, training a BP neural network, and obtaining an inversion model of MWHTSand MWTS-II fusion inversi
