Solar Irradiance and Meteorological Measurements for Phoenix Arizona

A collection of solar resource and meteorological measurements from the Solar Resource and Meteorological Assessment Project (SOLRMAP) at the Southwest Solar Research Park in Phoenix, Arizona. 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 Diffuse and Direct Irradiance patterns to model solar energy potential for specific locations.
• Correlate Global Irradiance measurements with Humidity and Pressure data to assess meteorological impacts on solar panel efficiency.
• Use Irradiance and Precipitation data to study the effects of weather events on solar resource availability.
• Apply Pyranometer and Radiometer measurements for calibrating and validating solar energy forecasting models.

Strengths

• Data is produced by the U.S. Department of Energy's National Renewable Energy Laboratory, an authoritative source in renewable energy research.
• The project is a collaboration with industry, designed to support the financing, design, and monitoring of large-scale solar power projects.
• Tags indicate the dataset includes multiple measurement types such as Diffuse, Direct, and Global Irradiance, Humidity, and Pressure.

Limitations

• The specific data schema, including column names and row count, is not provided in the input.
• The primary file format is HTML, which may not be optimal for direct quantitative analysis without parsing.
• The description focuses on project goals rather than the granular structure and volume of the underlying data.
