New England Forest Carbon and Water Yield Predictions Under Climate Scenarios

A grid of pixels covering New England and eastern New York at 2-kilometer resolution models the effects of climate change on forest ecosystems. The dataset contains predictions for net primary production and water yield from two runs of the PnET-II model, one using ambient conditions and one using modified temperature, precipitation, and CO2 levels. The model was developed by SCIOPS and validated against data for water yield and carbon exchange.

Use Cases

• Predict regional net ecosystem production (NEP) from temperature, precipitation, and CO2 concentration inputs.
• Analyze changes in net primary production (NPP) under a scenario of +6°C temperature and -15% precipitation.
• Model water yield impacts from a doubling of atmospheric CO2 and associated changes in water use efficiency.
• Validate forest carbon and water balance models using predicted NEP ranges from -85 to +275 g C/m²/yr for specific forest sites.

Strengths

• Model validated against data for water yield, gross/net carbon exchange, and biomass production for 4 forest/site combinations.
• Spatial coverage includes the entire New England and New York region at a 1 km resolution for regional analysis.
• Provides specific predicted value ranges, such as a regional average NEP of 76 g C/m²/yr and NPP from 150 to 350 g C/m²/yr.

Limitations

• Dataset size, row count, and specific column schema are unknown from the provided description.
• Model predictions are based on specific climate change scenarios (+6°C, -15% precip, 2x CO2) which may not represent all futures.
• Validation was limited to 4 forest/site combinations, potentially reducing generalizability across all ecosystem types in the region.
