VEMAP: Gridded Ecosystem Model Outputs for the U.S. from 1895 to 2100

Six ecosystem process models provide annual and monthly biogeochemical predictions for the Conterminous United States from 1895 to 2100. The data includes outputs for variables like Net Primary Production and Total Carbon Storage under two climate models and CO2 scenarios. Data is provided by the Vegetation/Ecosystem Modeling and Analysis Project (VEMAP) at NCAR.

Use Cases

• Projecting future ecosystem carbon storage based on Total Carbon Storage (TCS) and Net Ecosystem Productivity (NEP) variables.
• Comparing outputs from six different biogeochemical models (e.g., Biome-BGC, Century) for variables like Net Primary Production (NPP).
• Analyzing the impact of constant vs. increasing CO2 scenarios on ecosystem water flux using Actual Evapotranspiration (AET) data.
• Studying long-term vegetation dynamics from 1895 to 2100 using Leaf Area Index (LAI) and Total Vegetation Carbon (TVC) estimates.

Strengths

• Covers a 206-year time series from 1895 to 2100, enabling long-term trend analysis.
• Includes outputs from six distinct ecosystem process models, allowing for model intercomparison.
• Provides data for seven key biogeochemical variables, including Net Primary Production and Total Carbon Storage.
• Uses a consistent 0.5 x 0.5 degree spatial grid for the Conterminous United States.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to nasa_earthdata, as coverage is limited to the Conterminous United States.
