Abstract

There is a strong national interest in the observation of ocean surface winds with high spatial and temporal resolution for understanding tropical cyclones and their effects on weather and climate. In this paper, we will describe the details of an end-to-end simulation to support the development of the future airborne microwave Hurricane Imaging Radiometer (HIRAD). This new instrument will extend the measurements of the Stepped Frequency Microwave Imager (SFMR) from nadir looking only to a wide swath storm coverage of ± 60° earth incidence angel (EIA). A comprehensive simulation of the instrument radiances measurements during a hurricane overflight was developed based on realistic 3-D hurricane atmosphere and surface wind field using numerical weather models especially tunes to characterize hurricane environment. Afterwards, the simulated measurements were perturbed with instrument errors and input to the Maximum Likelihood Estimation (MLE) retrieval algorithm. Results will show statistical analysis and comparisons of the retrieved wind speeds and rain rates for different swath locations. © 2010 Copyright SPIE - The International Society for Optical Engineering.
