A 1 to 64 Hertz time series captured by a UK Meteorological Office C-130 aircraft during the 1992 ASTEX field campaign. This dataset provides high-frequency in-situ observations of marine stratocumulus clouds in the eastern North Atlantic Ocean. The data were collected to improve cloud and radiation parameterizations in General Circulation Models.
Use Cases
- Validate satellite-derived cloud properties like optical depth or liquid water path using in-situ aircraft measurements.
- Analyze the temporal evolution of cloud microphysical variables such as droplet concentration and size distribution at up to 64 Hz resolution.
- Investigate relationships between atmospheric state variables (e.g., temperature, humidity, wind) and cloud radiative properties for GCM parameterization.
- Study the spatial structure of marine stratocumulus clouds using the aircraft's flight track and associated geolocation data.
Strengths
- High-frequency time-series data collection at 1 to 64 Hz, enabling detailed process studies.
- Data collected during a coordinated, intensive field observation period combining satellite, airborne, and surface observations.
Limitations
- Temporal coverage is limited to the specific ASTEX campaign period in June 1992.
- Geographic scope is confined to the eastern North Atlantic Ocean region sampled by the aircraft flights.
- Specific data volume, row count, and available parameters are unknown from the description.
