Arctic Carbon Transport Footprints from CARVE Aircraft and Stations

Alaska and the Canadian Arctic are covered by this dataset of gridded atmospheric footprint data from the WRF-STILT model. It quantifies land surface influence on atmospheric constituents measured by the CARVE aircraft and ground stations from 2012 to 2015. The data, produced by NASA, is crucial for analyzing changes in Arctic carbon cycling and permafrost thaw.

Use Cases

• Analyzing source regions influencing carbon dioxide and methane concentrations measured during CARVE flights.
• Quantifying the land surface influence on atmospheric constituents at specific Arctic meteorological station locations.
• Modeling backward trajectories of air parcels to understand carbon transport pathways in the Arctic.
• Studying the spatial and temporal variability of atmospheric footprints for specific receptor points.

Strengths

• Data is derived from the established Weather Research and Forecasting (WRF) and Stochastic Time-Inverted Lagrangian Transport (STILT) models.
• Covers a multi-year time series from 2012 to 2015, capturing seasonal and interannual variability.
• Provides data for both airborne (CARVE flight paths) and ground-based (meteorological stations) receptor locations.

Limitations

• Source platforms disagree on the dataset's last update date (2016 vs. 2026).
• Specific column names, row counts, and dataset size are not provided by any source.
• The license is ambiguously listed as 'other-license-specified' without further detail.
