June 1992 data from the ASTEX field campaign, focusing on marine stratocumulus clouds in the eastern North Atlantic Ocean. The dataset contains in-situ aircraft measurements from a Fokker F27 ARAT, collected by French research groups including CRPE and LMD. It was designed to study energy transfer between the ocean surface and the atmospheric boundary layer.
Use Cases
- Validate satellite-derived heat and momentum flux estimates using in-situ turbulence measurements from the aircraft's nose boom.
- Analyze the relationship between cloud life cycles and fast-response sensor data for temperature, humidity, and wind.
- Model boundary layer processes using coordinated measurements of mean state variables like dew point and airspeed.
- Study spatial inhomogeneity of fluxes caused by mesoscale structures using the nested measurement strategy data.
Strengths
- Data from a coordinated, multi-instrument field campaign (ASTEX) in June 1992.
- Includes fast-response turbulence measurements from specialized sensors on a 5m nose boom.
Limitations
- Dataset is temporally limited to a single month (June 1992).
- Specific row counts, column details, and file formats are unknown.
- Geographic coverage is restricted to the eastern North Atlantic Ocean.
