HIPPO-2: Merged 1-Second Atmospheric Data from 2009 Aircraft Campaign

October to December 2009 data from the second mission of the HIAPER Pole-to-Pole Observations (HIPPO) study. The dataset merges 1-second aircraft state parameters with meteorological, atmospheric chemistry, and aerosol measurements from multiple investigator teams. It was reprocessed by the NCAR/EOL Research Aviation Facility using upgraded algorithms.

Use Cases

• Modeling atmospheric transport of greenhouse gases based on the 1-second aircraft position and wind speed data.
• Analyzing correlations between aerosol concentrations and meteorological conditions based on the merged measurements.
• Studying vertical profiles of atmospheric chemistry over the mission period based on the time-series data.
• Validating satellite retrievals of atmospheric constituents using the high-frequency in-situ measurements.

Strengths

• Provides 1-second temporal resolution for high-frequency atmospheric processes.
• Integrates data from multiple instrument teams, offering a merged view of aircraft state, meteorology, and chemistry.
• Data has been reprocessed with upgraded algorithms from NCAR/EOL, suggesting quality control.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a specific three-month campaign in 2009; temporal coverage is limited.
