Sensing Forest Water Dynamics from Space: Towards Predicting the Earth System Response to Droughts - Part II

October 26 - 28, 2020
California Institute of Technology - Pasadena, CA 91125

Workshop Overview:

The focus of our study is to develop the measurement concepts, observational architecture, and experiments that will increase our capacity to understand and predict the response of forest ecosystems to droughts and future climate extremes. We envisioned two workshops dedicated to the study. The first workshop, held in October 2019, addressed the state-of-the-art theory, models and measurement techniques for studying the water flow in soil-plant-atmosphere continuum and explored the mechanisms underlying the stress and response of plants to droughts. The participants discussed how these mechanisms are spatially and temporally scaled and to what extent the existing remote sensing observations can capture the forest water dynamics from space. Key science questions linking the water dynamics of forest ecosystems to carbon and energy cycles from plants to regional scales were discussed and several gaps in observations and modeling were identified.

In the second workshop, to be held in May 2020, we will pursue a number of avenues that would support needed technology development and science advancements to address the science questions identified in the first workshop. First, we will focus on developing the traceability between the science questions and observables in order to identify the needed measurements, and any necessary breakthroughs in observing architecture and performance. In particular, the study will explore how planned and potential exploratory microwave observations from space and their synergism with optical, hyperspectral, and/or thermal sensing can be used in sensing forest water dynamics from space. Second, we anticipate devising a strategy to support the goals of the study by a series of collaborative activities, including airborne and/or field campaigns, that include existing advanced technologies. These activities will address specific components of science and technology that are needed to improve our readiness and capability for a dedicated spaceborne mission going forward. Finally, we will outline the findings of the workshop to prepare a report and potentially a peer-reviewed publication.

Lodging for out-of-town attendees

There are a number of hotels (2 pages pdf, 600KB) that are close to the Caltech campus where we have a negotiated rate. (Please note that this negotiated rate does not guarantee you the lowest rate as there may be internet specials or AAA rates that may be better.)

Please note that with enough notice, you can reserve rooms for attendees at the Athenaeum, which has been recognized as a Platinum Club of America. Newly refurbished, it is conveniently located on the Caltech Campus. Contact Janet Seid if you would like to check the availability of this option.

Parking (for Visitors and for JPL Personnel)

For Visitors: From the Arroyo Parkway, turn right (east) on Del Mar Avenue. Proceed approximately one and a quarter miles. The Caltech campus will be on your right. Turn right (south) onto Wilson Avenue. Turn right into the North Wilson Structure and park in an unmarked spot. Buy a parking permit from the kiosk located inside the North Wilson Structure or request one ahead of time from KISS.

For JPL Personnel: JPLers may use their JPL hang tag for parking or request a special parking hangtag from the JPL parking office. Employees who do not have on-Lab parking privileges can obtain a hang tag created for this purpose from JPL parking coordinator Robert Kennedy (818-354-4586, Building 310-108B, 9/80 schedule). Please park in an unmarked spot in the North Wilson Structure located on Wilson Avenue.
