Solar Irradiance and Meteorological Measurements for Cedar City, Utah

A collection of high-quality solar resource and meteorological measurements from the Solar Resource and Meteorological Assessment Project (SOLRMAP) in Cedar City, Utah. It is produced by the U.S. Department of Energy's National Renewable Energy Laboratory in collaboration with industry partners to support solar power project deployment and model development.

Use Cases

• Analyze solar irradiance components (Global, Direct, Diffuse) to assess solar energy potential for project siting.
• Correlate meteorological variables like Humidity and Pressure with solar irradiance measurements for weather impact studies.
• Use Precipitation data alongside irradiance measurements to model soiling losses on solar panels.
• Validate and calibrate solar resource models using high-quality, ground-based Irradiance measurements from the Radiometer and Pyranometer instruments.

Strengths

• Data is produced by the National Renewable Energy Laboratory, a leading authority in renewable energy research.
• Project focuses on high-quality measurements to support the financing and design of large-scale solar power projects.
• Dataset includes multiple solar and meteorological variables such as Irradiance, Humidity, and Pressure.

Limitations

• Specific data volume (row count) and granularity (e.g., temporal resolution) are not provided in the input.
• Geographic coverage is limited to a single location (Cedar City, Utah), limiting broader regional analysis.
• Data format is listed as HTML, which may not be a structured, machine-readable format like CSV or JSON.
