WRF-Simulated Daily Hydroclimate Conditions for the US Puget Sound Region, 1981-2020

WRF-simulated daily hydroclimate data over the US Puget Sound region covers a 40-year period from 1981 to 2020. The dataset includes six key variables at a 6-kilometer grid spacing, such as precipitation and 2-meter temperature. It was produced by Xiaodong Chen of the Pacific Northwest National Laboratory and is associated with research on ENSO and MJO impacts.

Use Cases

• Analyzing precipitation patterns and extremes based on the PREC_ACC_NC variable.
• Studying temperature trends and variability based on the 2-meter temperature (T2) data.
• Modeling snowpack and water resources based on the snow water equivalent (SNOW) variable.
• Investigating atmospheric moisture transport based on the integrated water vapor (IWV) and integrated vapor transport (uvIVT) variables.
• Assessing wind patterns and divergence based on the WindDiv variable for regional climate studies.

Strengths

• Data spans a 40-year period from 1981 to 2020, providing a long-term climate record.
• Includes six specific hydroclimate variables simulated at a high 6-kilometer spatial resolution.
• Model configuration and validation are documented in peer-reviewed publications by Chen et al. (2018, 2019).

Limitations

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