SOFIA program data from the 1992 ASTEX field experiment studied energy transfer between the ocean and atmosphere. French research groups collected measurements using a trailing thermistor and bucket system to estimate heat, humidity, and momentum fluxes. The dataset focuses on the eastern North Atlantic Ocean from June 1 to June 28, 1992.
Use Cases
- Validate satellite-derived estimates of ocean-atmosphere heat and humidity fluxes using in-situ thermistor and bucket measurements.
- Study the spatial inhomogeneity of energy fluxes caused by mesoscale oceanic and atmospheric structures during ASTEX.
- Improve GCM cloud parameterizations for marine stratocumulus systems by analyzing flux data across nested observational scales.
- Investigate the life cycle and radiative properties of stratocumulus clouds using coordinated surface observations from the FIRE program.
Strengths
- Data collected during a coordinated, month-long intensive field observation period (June 1-28, 1992).
- Measurements designed to estimate fluxes at multiple scales from local to mesoscale (50 km).
- Thermistor data have been calibrated.
Limitations
- Thermistor data have not undergone quality control procedures.
- Sample size and temporal resolution are unknown.
- Dataset is temporally stale, with no updates since the 1992 campaign.
