WRF-STILT Atmospheric Footprint Data for Boston 2013-2014

Particle trajectory and footprint data model the atmospheric transport of CO2 and CH4 for two measurement receptors in Boston, MA. The dataset covers an 18-month period from July 2013 to December 2014 and was produced by NASA using the WRF v3.6.1 and STILT models. It includes footprints at two spatial scales: 1-degree resolution for North America and 0.1-degree for a local near-field region.

Use Cases

• Attributing measured CO2 and CH4 concentrations to upwind surface flux sources using the provided footprint fields.
• Validating or improving atmospheric transport models by comparing with the STILT particle trajectory data.
• Analyzing the spatial and temporal influence patterns on Boston receptors from regional and continental sources.
• Studying seasonal variations in atmospheric transport over an 18-month period for a major urban area.

Strengths

• Provides modeled data for an 18-month continuous period (July 2013 - December 2014), enabling seasonal analysis.
• Includes footprints at two distinct spatial resolutions (1-degree and 0.1-degree) for both continental and local-scale analysis.
• Derived from a specific, documented model version (WRF v3.6.1), ensuring reproducibility.
• Hosted by NASA and available on multiple platforms, indicating scientific importance and reliability.

Limitations

• Exact data volume, row counts, and column names are unspecified across all source platforms.
• Conflicting 'last updated' dates exist between sources (2014-12 -31 vs. 2026-03-12), creating uncertainty about metadata freshness.
