Remote Impacts of the 2020 Western U.S. Drought from CESM2 Simulations

Western U.S. drought impacts simulated by the Community Earth System Model (CESM) version 2.2.2. The dataset consists of 1040 netCDF files, including 880 monthly and 160 daily averages, organized from 4 experiments with 20 ensembles each. Ana Sena produced this dataset, last updated on May 22, 2026.

Use Cases

• Analyze drought teleconnections based on 4-dimensional atmospheric variables.
• Validate climate model ensemble outputs based on 20 ensembles per experiment.
• Study atmospheric pressure-level responses to drought based on the 4-dimensional array structure.
• Compare monthly versus daily climate variability based on the separate monthly and daily average folders.

Strengths

• Dataset comprises 1040 simulation output files.
• Includes 880 monthly average files and 160 daily average files.
• Data is organized from 4 distinct experiments, each with 20 ensembles.
• Files are in netCDF format, a standard for geospatial and time-series data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
