Description

Input Data from Oak Ridge National Laboratory DAAC (Distributed Archive Access Center) ftp://daac.ornl.gov/data/npp/

NPP_TM196.pdf - Documentation: History and variable descriptions for EMDI and GPPDI datasets. Olson et al. 2001. Global and Regional Ecosystem Modeling: Databases of Model Drivers and Validation Measurements. ORNL/TM-2001/19

EMDI (Ecosystem Model-Data Intercomparison) – most complete, well-documented data

EMDI_ClassA_NPP_81_R1.csv – original DAAC File
EMDI_ClassA_NPP_81_R1MH.csv – edited for input to software
EMDI_ClassB_NPP_933_v2.csv – original DAAC File
EMDI_ClassB_NPP_933_v2MH.csv – edited for input to software

GPPDI (Global Primary Production Data Initiative) – less documented, multiple measurements per sits

GPPDI_ClassA_Flags_162.csv – original DAAC File
GPPDI_ClassA_NPP_162_R1.csv – original DAAC File
GPPDI_ClassA_NPP_162_RMH.csv – edited for input to software
GPPDI_ClassB_Flags_2363.csv – original DAAC File
GPPDI_ClassB_NPP_2363.csv – original DAAC File Note that 879 of the 2363 cases have missing ANPP values and were not used in any figures
GPPDI_ClassB_NPP_2363MH.csv – edited for input to software

Output Files with merged Class A and B data with Calculated Values of eANPP used for creating figures 1 and 4 (eANPP created by dividing ANPP by length of growing season).

outforEMDIAB_FORESTS_Feb1710.csv - equivalent to Huston and Wolverton 2009:Fig. 11E minus Chinese sites removed in DAAC revision R1
outforGPPDI_ABForestsFeb1910.csv - for comparison only, does not represent published figures, does not include Chinese sites removed in DAAC revision
outforGDDPI_AB_AllNatFeb1910.csv - data used for Fig. 4A, All natural vegetation types (desert, tundra, forests, etc.), excluding managed systems and wetland

Variable names used in output files

SiteNum – Site number used as unique identifier for sites in DAAC NPP datasets
Lat – Latitude of site
Long – Longitude of site
Latpoint – alternative latitude value for extracting data from global grids
Longpoint – alternative longitude for extracting data from global grids
Elevation – elevation of site in meters
BiomeType – descriptor of biome type for site
AnnTemp – Average annual Temperature– degrees C
AnnPPT – Average annual precipitation (mm)
ANPPCarbon – Measured aboveground net primary productivity in mass of carbon (g C m-2 yr-1)
TNPPCarbon – Estimated total (above and belowground) NPP in mass of carbon (g C m-2 yr-1) - data not used because belowground NPP was estimated not measured
ANPPBionass – Measured aboveground net primary productivity in units of dry biomass (g m-2 yr-1) – calculated by multiplying ANPP Carbon by 2.1053
TNPPBiomass - Estimated total (above and belowground) NPP in units of dry biomass (g m-2 yr-1) – calculated by multiplying TNPP Carbon by 2.1053 - data not used because belowground NPP was estimated not measured
eNPP – Aboveground net primary productivity in units of dry biomass per month (g m-2 mon-1) – calculated by dividing ANPPBIomass by length of growing season in months
GrSeasMonths – estimated length of growing season for woody vegetation in months, calculated from global climate maps with growth limited by either temperature or precipitation (see Huston and Wolverton 2009)
