Abstract

In order to expand the adaptability of the microwave radiometer (MWR) to the marine environment, the MWR tropospheric temperature and humidity profile system for the marine environment was developed. An idea of retrieving the 0~10km temperature and humidity profile by integrating the atmospheric experience database and the differential evolution algorithm (DE) was proposed. Through a large number of temperature and humidity profile simulation calculations, the feasibility of the algorithm was finally proved. The simulation results show that the root mean squared error (RMSE) of temperature profile retrieved by DE is 4.3K, the mean absolute error (MAE) is 3.4K, the RMSE of humidity retrieved by DE is 22.9%, and the MAE is 19.1%. The algorithm based on the fusion of atmospheric experience database and DE has the characteristics of independent of historical data, which provides a new idea for the marine atmospheric detection lacking of historical data.
