Abstract:

This paper details a technique for deconvolving satellite microwave radiometer brightness temperatures into component passive microwave emissions from water and land. This process utilizes high resolution visible and infrared satellite observations from the Aqua and Terra MODIS spectro-radiometers to generate antenna gain pattern corrected fractional weights for water coverage within each radiometer field of view. Our results comparing component brightness temperatures generated from in situ and simulated data to deconvolved component and observed brightness temperatures indicate a significant decrease in the bias and root mean squared error of land based passive microwave emissions.
