    • ABoVE: TVPRM Simulated Net Ecosystem Exchange, Alaskan North Slope, 2008-2017

    Metadata Updated: December 6, 2023

    This dataset includes hourly net ecosystem exchange (NEE) simulated by the Tundra Vegetation Photosynthesis and Respiration Model (TVPRM) at 30 km horizontal resolution for the Alaskan North Slope for 2008-2017. TVPRM calculates tundra NEE from air temperature, soil temperature, photosynthetically active radiation (PAR), and solar-induced chlorophyll fluorescence (SIF) using functional relationships derived from eddy covariance tower measurements. These relationships were then scaled over the region using gridded meteorology and a vegetation map. The site-level CO2 fluxes fell into two distinct ecosystem groups: inland tundra (ICS, ICT, ICH, IVO) and coastal tundra (ATQ, BES, BEO, CMDL). The expanded modeling framework allowed for the easy substitution of ecological behaviors and environmental drivers, including the choice of representative inland tundra site, coastal tundra site, vegetation map (CAVM, RasterCAVM, or ABoVE-LC), meteorological reanalysis product (NARR or ERA5), and SIF product (GOME2, GOSIF, or CSIF). Using all of these variations generated an ensemble of 288 different TVPRM simulations of regional CO2 flux and one additional simulation option with added aquatic and zero curtain fluxes (AqZC).

    TVPRM net ecosystem exchange: Surface upward mass flux of carbon dioxide expressed as carbon due to emissions from natural sources for 2015-07-01 (left) and 2015-10-01 (right). The data were derived from the TVPRM model for 2015 that used "IVO" as the inland site, Barrow "CMDL" as the coastal site, "RasterCAVM" as the vegetation map, "NARR" as the meteorological product, and "GOME2" as the SIF product (as described by the source file name).
