Grassland - Modeled DNDC Soil and GHG Outcomes for Grasslands

Modeled DNDC Soil and GHG Outcomes for Grasslands The Denitrification-Decomposition (DNDC) model was used to simulate carbon and nitrogen soil dynamics in grassland soils.   Explore the Grassland DNDC Modeling Results DNDC Summary Data are available for soil carbon changes and GHG emissions. The soil and GHG outcomes (methane, as well as indirect and direct nitrous oxide) are based on the use of the vegetation type and herbaceous productivity data as input to the DNDC model. Data are currently available for the years 2015-2021. The grasslands DNDC modeling results are available at the US EPA Level 3 Ecoregion scale. View Data ...

Grassland - Vegetation Types and Productivity

Vegetation Types and Productivity Data are available for vegetation type, herbaceous net primary productivity (NPP), herbaceous NPP trends, and herbaceous NPP deviation from what would be expected based on weather alone. Remote-sensing derived, CONUS-wide grassland data for various vegetation type and health metrics. Data are currently available for the years 2015-2021. The vegetation health data are available at the watershed (HUC8) and Crop Reporting District (CRD) geographic scales.   Explore the Vegetation Types and Productivity Vegetation Types Annual average plant functional type (PFT) by HUC8 and CRD for years spanning 2015 to 2021. PFTs include: Annual Forbs & Grasses, Perennial Forbs & ...
