Stratocumulus Cloud Field Simulations Using RAMS Model, 6 Cases

Six high-resolution RAMS model simulations of stratocumulus cloud fields over a 3-hour period. The dataset includes a control case and five variations with modified temperature or humidity profiles to study effects on cloud entrainment. The simulations were performed by researchers at the Centre National de la Recherche Scientifique, based on the DYCOMS-II case from Stevens et al. (2003).

Use Cases

• Analyzing the impact of temperature inversion strength on cloud entrainment rates based on the modified profile simulations.
• Studying the sensitivity of stratocumulus cloud fields to initial moisture conditions based on the water vapor profile case.
• Validating remote sensing analytical models for cloud profiles based on the dataset's application described in Shang et al. (2022).
• Comparing cloud dynamics under different thermodynamic forcings based on the six simulation cases.

Strengths

• High spatial resolution with a fixed horizontal resolution of 100 m and vertical bin spacing of 50 m.
• Includes 6 distinct simulation cases designed to test sensitivity to specific thermodynamic parameters.
• Based on a well-established initial state (DYCOMS-II case) adapted from peer-reviewed literature.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
