T006:
Ocean Remote With Global Navigation Satellite System Reflectometry (GNSS-R)


Session ID#: 28625

Session Description:
Reflectometry is a new method of ocean remote sensing, utilizing scattered “signals of opportunity” from the Global Navigation Satellite System. GNSS-R embodies some aspects of both active scatterometry and passive radiometry. New methods for retrieving ocean wind speed, sea surface height., sea surface roughness, and significant wave height have been derived for GNSS-R observations from fixed, airborne and spaceborne platforms. With the recent launch of the 8-satellite CYGNSS (Cyclone GNSS) constellation, GNSS-R data will be widely available for ocean remote sensing in the tropics. This tutorial will review the fundamental principles of GNSS-R, including forward models, observables and inverse methods. A review of current applications of GNSS-R to ocean science and applications will be provided
