2. EC-MOD - Gridded carbon and water fluxes over North America (upscaled from AmeriFlux and Fluxnet-Candada data)

 

The EC-MOD data set consists of gross primary productivity (GPP), net ecosystem exchange (NEE), ecosystem respiration (ER), and evapotranspiration (ET) at 1km spatial resolution and 8-day time step over North America for the period from March 2000 to December 2012 (Xiao et al. 2014). It was developed from eddy covariance (EC) flux data, MODIS data streams, micrometeorological reanlaysis data, stand age, and aboveground biomass data using a data-driven approach (Xiao et al. 2008, 2010, 2011).

 

Gridded GPP, NEE, ER, and ET fields for North America (EC-MOD)        

     Spatial resolution: 1 km*1 km

     Spatial coverage: North America

     Temporal resolution: 8-day

     Temporal coverage: March 2000 - December 2012

The EC-MOD data set is highly constrained by eddy flux data, and is useful for scientific analysis (e.g., spatiotemporal patterns of carbon and water fluxes), model validation, and intercomparison analysis. EC-MOD has been used to evaluate ecosystem models (Sun et al. 2011; Huntzinger et al. 2012; Raczka et al. 2013) and atmospheric inversions (Dang et al. 2011; Deng et al. 2013).
