Abstract:
To date, the majority of studies addressing spatial patterns of vegetation carbon gain have focused on remote sensing of canopy leaf area index (LAI), which has been related to productivity across large resource gradients and can be estimated using spectral vegetation indices such as NDVI. However, a growing body of evidence suggests that approaches based solely on LAI may be problematic in dense plant canopies and in systems where variation in growth is driven to a greater extent by variation in leaf-level photosynthetic potential. Because photosynthetic potential is strongly related to biochemical constituents such as nitrogen and chlorophyll concentrations in foliage, the ability to incorporate canopy chemistry into large-scale carbon cycling research would represent an important contribution to NACP research goals.
The work being conducted under this project is designed to address these issues by using high spectral resolution remote sensing and by focusing on canopy variables associated with photosynthetic capacity as well as leaf area. This is achieved through a series of coordinated field and remote sensing campaigns aimed at mapping canopy nitrogen and chlorophyll concentrations and associated patterns of canopy carbon exchange over a diverse network of AmeriFlux and NACP field sites. Specific tasks designed to meet these goals include the following: (1) Extend present methods for canopy chemistry remote sensing by seeking a generalizeable approach that can be applied across multiple scenes, and vegetation types; (2) Map fine-scale patterns of canopy nitrogen, chlorophyll and leaf area index over a series of AmeriFlux and NACP research sites; (3) Generate high-resolution estimates of GPP and NPP over a ~10x10 km2 area surrounding each site; (4) Use the high-resolution coverages as an intermediary for interpretation and testing of C-flux estimates from existing satellite products (MODIS GPP) and from a newly-developed production efficiency model (VPM); (5) Conduct a cross-site synthesis activity designed to examine the relative influence of canopy structure versus chemistry on broad-scale patterns of canopy CO2 exchange.
Comment:
This project involves mapping canopy nitrogen concentrations in the landscapes surrounding a series of flux tower sites and extending estimates more broadly with satellite remote sensing. Data we collect at several sites may be relevant to the Mid-Continent Campaign (Bondville, Ill. Willow Creek, WI, Mead, NE, Morgan Monroe, IN), although most have been sampled in 2005 and 2006. With some coordination, we may be able to collect additional data in 2007. We'd be glad to work with MCI people if this would be useful. We may also be able to add one or two strategically located sites if information on canopy chemistry would be a useful addition to existing plans.
