Arctic Atmospheric Particle Trajectories from Multiple Platforms, 2016-2019

Particle trajectory files simulate the 10-day backward atmospheric transport influencing greenhouse gas concentrations at Arctic receptors above 45°N from 2016 to 2019. Data originates from the ORNL_CLOUD organization and integrates observations from flux towers, aircraft flask samples, and the OCO-2 satellite. This dataset extends the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) research.

Use Cases

• Modeling source-receptor relationships for methane and carbon dioxide using backward-in-time particle trajectories.
• Analyzing atmospheric transport patterns from flux tower, aircraft, and satellite observation sites.
• Generating high-resolution (0.1°) or low-resolution (0.5°) footprint fields for surface flux inversion studies.
• Comparing modern Arctic transport dynamics with legacy datasets from the CARVE project.

Strengths

• Covers a multi-year time range (2016-2019) for the sensitive Arctic region above 45°N.
• Integrates data from three distinct observational platforms: fixed flux towers, aircraft flask packages, and satellite observations.
• Provides particle trajectories at two spatial resolutions (0.1° and 0.5° grids) for flexibility in analysis.

Limitations

• Specific column names, row counts, and total dataset size are not provided by any source.
• Sources conflict on the last updated date, reporting either 2019-12-31 or 2026-03-13.
• License is ambiguously listed as 'other-license-specified' without explicit terms.
