PISTON 2019: Multi-Instrument Atmospheric and Oceanographic Data from RV Sally Ride

September 2019 data from the Propagation of Intra-Seasonal Tropical Oscillations (PISTON) field campaign in the Philippine Sea. This dataset results from a joint NASA, ONR, and NOAA effort to study multi-scale tropical convection and air-sea interactions, specifically targeting the Boreal Summer Intraseasonal Oscillation (BSISO). It integrates measurements from multiple shipboard instruments including CTD, ADCP, SEA-POL radar, and microstructure profilers.

Use Cases

• Analyzing the vertical structure of ocean currents and water properties based on Acoustic Doppler Current Profiler (ADCP) and Conductivity, Temperature, Depth (CTD) data.
• Studying atmospheric convection and cloud properties using measurements from the SEA-going POLarimetric Doppler Radar (SEA-POL).
• Investigating ocean turbulence and mixing processes with data from the Chameleon Microstructure Profiler (CHAM).
• Examining the relationship between surface winds, radiation fluxes, and upper-air conditions to understand air-sea interaction drivers.

Strengths

• Integrates data from seven distinct instrument systems, providing a multi-faceted view of the ocean-atmosphere system.
• Part of a coordinated field campaign involving three ship cruises, eight profiling floats, and two ocean moorings, suggesting contextual richness.
• Data collection is explicitly stated as complete.

Limitations

• Column names and specific data formats are not provided in the available metadata, complicating initial assessment of data structure.
• Conflicting 'last updated' dates (2019-09 26 and 2026-04-09) exist across platform entries, creating uncertainty about metadata maintenance.
• Exact row counts and file sizes are unknown.
