Carbon Dioxide and Water Flux Responses to Extreme Weather and Climate Anomalies: A Fluxnet Synthesis

在这个项目中，研究人员将在个别通量塔站点的发现的推动下进行综合，极端天气和气候事件（如干旱、洪水、飓风和冰暴）导致测量的当地碳和水预算的关键组成部分出现明显和持久的异常。pi将评估生态系统对极端事件响应中通量塔站点的共性程度，得出这些响应的连贯描述，并利用遥感数据推断对生态系统，特别是植被的空间连贯和持续影响，这些影响随后可能在更大的空间尺度上影响碳和水平衡以及气候轨迹。pi还将评估各种复杂程度的陆地表面模式在观测气象驱动下模拟观测到的陆地状态变量和通量对极端事件的响应的能力。该项目完全由一组职业生涯初期的科学家组成。这项工作得到了美国国家科学基金会地球系统碳和水招标项目的支持，这是地球科学理事会提供的跨学科资助机会。

In this project researchers will perform a synthesis motivated by findings at individual flux tower sites that extreme weather and climate events (e.g., droughts, floods, hurricanes, and ice-storms) lead to pronounced and protracted anomalies in key components of the measured local carbon and water budgets. The PIs will assess the degree of commonality across flux tower sites in the response of the ecosystem to extreme events, derive a coherent description of these responses, and use remote sensing data to extrapolate spatially coherent and persistent impacts on ecosystems, specifically on vegetation, that subsequently may impact carbon and water balances and climate trajectories on a larger spatial scale. The PIs will also assess the ability of land surface models spanning a wide range of complexity to simulate the observed response of terrestrial state variables and fluxes to extreme events when driven by observed meteorology. The project is composed entirely of a team of early-career scientists.This work is supported under the NSF Carbon and Water in the Earth System solicitation, an interdisciplinary funding opportunity from the Directorate of Geosciences.
