Chapter\, GRS\n\nSpeaker(s): Prof. Mehmet Kurum\, \n\nAgenda: \nThere is significant evidence that vegetation water content\, known as VWC\, ca n serve as a useful measure of water status as it is directly linked to th e moisture content of living fuel. Improved temporal and spatial quantific ation of VWC variations is expected to aid in the improved evaluation of h ow forests respond to drought\, including tree mortality and wildfire risk . Direct measurement of VWC dynamics remotely can also be crucial for unde rstanding and modeling hydrological and ecological processes. Presently\, only coarse spatial resolution (25 – 50 km) vegetation optical depth (VO D) is globally observed by satellites. These observations are mainly deriv ed from opportunistic analyses of measurements that were initially intende d for other scientific purposes. In addition\, validating spaceborne VOD p oses a significant challenge due to lack of systematic ground-based VOD ob servations at the moment. Recently a new methodology called the Global Nav igation Satellite System (GNSS) Transmissometry (GNSS-T) technique has gai ned attention to monitoring VWC directly. The method uses stationary or mo bile GNSS receivers under the forest canopy\, accompanied by an additional unit in the open area as reference. The logarithmic difference between th e two measurements yields information on forest transmissivity (water cont ent). This relatively new remote sensing (non-intrusive) approach could tr ansform forest VWC monitoring studies. Its optimal interpretation\, use\, and relation to VWC have yet to be comprehensively explored.\n\nVirtual: h ttps://events.vtools.ieee.org/m/391721 LOCATION:Virtual: https://events.vtools.ieee.org/m/391721 ORGANIZER:w.neill.kefauver@lmco.com SEQUENCE:3 SUMMARY:GRSS Webinar: Unveiling the Potential of GNSS Transmissometry (GNSS -T) for Remote Sensing of Forest Canopy Water Content: Challenges and Path ways to 'Radio Realistic' Forest Scene Generation URL;VALUE=URI:https://events.vtools.ieee.org/m/391721 X-ALT-DESC:Description: <br /><p>Speaker: <strong>Prof. Mehmet Kurum\,&nbsp \;</strong>The University of Georgia\, USA</p>\n<p>Thursday\, December 21\ , 2023 <a href="https://www.timeanddate.com/worldclock/fixedtime.html?msg= Unveiling+the+Potential+of+GNSS+Transmissometry+%28GNSS-T%29+for+Remote+Se nsing+of+Forest+Canopy+Water+C&amp\;iso=20231221T11&amp\;p1=43&amp\;ah=1"> 11 AM Eastern Time</a></p>\n<p>The GNSS-T&nbsp\;method&nbsp\;uses stationa ry or mobile GNSS receivers under the forest canopy\, accompanied by an ad ditional unit in the open area as reference.
