OCO-2和OCO-3具有迄今为止最高的星载SIF反演空间分辨率,OCO-2和OCO-3的目标和快照区域模式观测模式是独特的。这些卫星数据数据为生物多样性全球目标地点提供了数百到数千次SIF反演,并为我们更好地了解整个生物群落的冠层植被SIF发射提供了机会。 结果 图1.GOSAT、OCO-2和OCO-3的年度(2020年)和2020年6月平均每日...
OCO-2 SIFCarbon assimilation systemThe gross primary productivity (GPP) is the largest carbon flux in the terrestrial carbon cycle. Constraining GPP is critical for understanding the terrestrial carbon sources and sinks. In this study, we attempted to constrain the terrestrial GPP at regional to ...
SIF工具 创建了公共github存储库以支持AGU 2018上的荧光应用研讨会: : 此处提供的示例和工具的主要目的是帮助尚未熟悉SIF数据的用户了解其用法,缺陷以及所需的编程工具。 无论如何,都要具备一些脚本编程经验才能使用卫星数据,我们选择使用开放源代码软件,同时使用python和R。Jupyter的python笔记本(以及Julia等)提供了一...
Solar-induced chlorophyll fluorescence (SIF) opens a new perspective on the monitoring of vegetation photosynthesis from space, and has been recently used to estimate gross primary productivity (GPP). However, previous studies on SIF were mainly based on satellite observations from the Greenhouse Gases...
As pathfinder missions, NASA’s Orbiting Carbon Observatory-2 and its sister mission OCO-3 have remarkably expanded global CO2observation coverage for over nine years. Additionally, both missions retrieve solar-induced chlorophyll fluorescence (SIF) data, an indicator of photosynthetic activity, at ...

SIF数据协同通过使用土壤水分主动-被动卫星(SMAP)获取土壤水分数据,以及使用轨道碳观测卫星(OCO-2)获取的太阳诱导叶绿素荧光(SIF)数据来估算总初级生产力(GPP),为理解大区域土壤水分与陆地光合作用之间的关系提供了新的机会.美国新罕布什尔大学的Li等利用来自SMAP的根区土壤湿度,GPP数据(空间分辨率为9 km)和OCO-2 ...
We compare recent daily mean SIF products (one from the Orbiting Carbon Observatory‐2 [OCO‐2] and two from the Global Ozone Monitoring Experiment–2 [GOME‐2], GlobFluo [GF] and NASA‐v28 [N28], missions), averaged at 0.5°×0.5° spatial resolution and 16‐day temporal resolution, at...
