Abstract:
A new microwave radiometric ocean surface emissivity model has been developed to support the analysis and design of the new airborne Hurricane Imaging Radiometer, HIRAD. This radiative transfer model extends current ocean surface emissivity capabilities to higher wind speeds and incidence angles. This model utilizes a variety of empirical data sources many of which were collected in hurricanes.Keywords:
Radiometry
Microwave radiometer
Empirical modelling
Based on the microwave radiative transfer theory,three radiative transfer models are used to simulate the brightness temperature measured by a satellite microwave radiometer under conditions of no precipitation or ice.A forward model for the development of the retrieval algorithm is established through comparison of the simulated results with the simultaneous satellite measurements.Based on the simulation by the selected forward model,a multiple linear regression algorithm is presented for the retrieval of oceanic and atmospheric parameters including sea surface temperature,surface wind speed,integrated water vapor and integrated cloud liquid water from satellite microwave radiometer microwave.
