SOLVE I DC-8 Arctic Aerosol In-situ Measurements

NASA's SOLVE campaign deployed a DC-8 aircraft to collect in-situ aerosol data for validating the SAGE III satellite. The dataset includes particle size spectra from instruments like the FSSP, PCASP, CNC, FCAS II, and N-MASS. This multi-platform NASA effort involved 28 total flights across two Arctic winter phases from late 1999 to spring 2000 and again in 2003.

Use Cases

• Validating SAGE III satellite aerosol and ozone measurements using in-situ particle size and concentration data.
• Analyzing the relationship between aerosol properties and polar ozone depletion processes in the Arctic winter.
• Studying the vertical and horizontal distribution of nucleation-mode and accumulation-mode aerosols in the stratosphere.
• Correlating in-situ aerosol measurements with co-located DC-8 data on ozone, ClO/BrO, and meteorological parameters.

Strengths

• Data originates from a major, multi-program NASA campaign (UARP, AEAP, ACMAP, EOS) with a clear validation objective.
• Includes measurements from five specialized aerosol instruments (FSSP, PCASP, CNC, FCAS II, N-MASS) providing detailed particle spectra.
• Campaign involved 28 coordinated flights across aircraft, balloon, and ground-based platforms, ensuring multi-faceted data collection.
• Focus on the high Arctic winter provides targeted data on a critical period for polar ozone depletion.

Limitations

• Critical metadata conflicts exist: one source describes this as 'Aerosol_AircraftInSItu' data, while another describes it as 'Analysis' data with modeled trajectories, creating uncertainty about the core content.
• No column names, row counts, or file sizes are provided from any platform, hindering assessment of data structure and volume.
• License is ambiguously listed as 'other-license-specified' without details, requiring user investigation.
