Hurricane Research with ONR-Supported Drop-Sondes
Abstract
Funds are provided to advance the technology of drop-sondes, and to use them in research campaigns to support ONR DRI field campaign""s. The PI~s effort in this project involves developing and testing further improvements to the telemetry and data-handling system,"" improved H2O measurements, and a new method to obtain vertical air-motion velocities. He will participate in a major research camp"aign in 2019-2020. The three technical efforts are: 1) Improve the telemetry from drop-sondes by implementing a new Forward Error Correcting code through the implementation of Time Division Multiplexing (TDM) that allows much higher sampling density for this new" system. He will pursue advancements that will improve range, data reliability, and an increase in the number of sondes that can be" tracked in the air at the same time. 2) He will improve the H2O measurements by drop-sondes by replacing the polymercapacitive sensors (less than ideal) with COTS sensors that perform better at high (cold) altitudes where the H2O concentrations are very low. He" will collaborate with Yankee Environmental Systems, Inc. in calibration, data handling, and design assistance in sensor interface e"lectronics. 3) He will develop add-on instrumentation that will improve the accuracy of the vertical wind velocity retrievals from these drop-sondes.
