SEAC4RS DC-8: Atmospheric In-Situ Measurements from 2013 Campaign

SEAC4RS_Miscellaneous_AircraftInSitu_DC8_Data contains ancillary in-situ measurements from the NASA DC-8 aircraft during the 2013 SEAC4RS field campaign. The dataset features model data from the Goddard Earth Observing System Model (GEOS-5) and was collected to study pollutant redistribution, aerosol-cloud interactions, and to validate satellite instruments. Flight operations were based in Houston, Texas, during August and September 2013.

Use Cases

• Analyzing the evolution of gases and aerosols in deep convective outflow based on trace gas and aerosol property measurements.
• Investigating the influence of biomass burning and anthropogenic pollution on meteorology based on radiative flux and meteorological parameter data.
• Calibrating and validating future satellite instrument retrievals using comprehensive in-situ and remote sensing measurements.
• Studying the semi-direct and indirect effects of aerosols on climate through changes in the atmospheric heat budget and cloud microphysics.

Strengths

• Data originates from a major, well-documented NASA airborne field campaign (SEAC4RS) with clear science objectives.
• Integrates observational aircraft data with outputs from the authoritative GEOS-5 model.
• Cross-platform presence on NASA Earthdata and Data.gov signals its importance and curation.

Limitations

• Column names and specific data structure are unknown, limiting immediate usability.
• Conflicting 'last updated' dates (2013-09 23 and 2026-04-09) create uncertainty about metadata maintenance.
• Dataset size and row counts are not provided in any source.
