This submission presents preliminary results concerning the use of new observations from the A-Train Constellation for testing a new technique of remotely sensing hurricane intensity from space based on modeling a hurricane as a balanced, convectively neutral vortex. The key observational requirements are simultaneous, accurate measurements of cloud-top height, cloud-top temperature and cloud profiling information across the center of the storm, although there are ways to bypass the need for cloud-top temperature. In this study, MODIS on board Aqua provides an estimation of the cloud-top temperature and the near-simultaneous CloudSat observations provide the essential cloud-top height and cloud profiling information. Initial results indicate that the new technique is a promising method for estimating storm intensity when compared, post facto, to the best track database. Potential uncertainties and room for further refinement of the technique are discussed.wrf recording  Recorded presentation
