LOADPATH, LLC — Department of Defense SBIR Phase II: N08-195

Description

We will develop a fast response, commercially-available bulk polymer sensor to our field-proven eXpendable Digital Dropsondes (XDD). This task is not only sensor development, but requires developing a precision, automated system to perform multi-point absolute calibration of each polymer sensor plus a means to store these values onboard. This capability will enable real time vertical profiles of RH in engineering units to support direct ingest into meteorological numerical weather prediction models. Reliable, repeatable precision individual sensor calibration represents a major technical task. The second option task involves developing new telemetry receiver hardware and software algorithms supporting very long range UHF data communications. Improved telemetry reliability is essential to eliminate data drop outs that cause discontinuities in observations. Data availability, especially down near the ocean surface in heavy precipitation as is frequently encountered within the inner core of TC/hurricanes, is a key goal. The result will produce a flight-demonstrated practical real time water vapor observation system capable of measuring moisture from the ocean surface to the top of the storm up to 18km, or flight level 650.
