Solar Irradiance and Meteorological Dataset (June 2021)

Overview

This dataset contains solar irradiance and meteorological data collected from 1st Jan, 2021 to 31st Dec, 2021. The data is intended to assist in solar energy prediction, weather analysis, and environmental research. The dataset now includes two additional columns, raw_images and processed_images, which hold corresponding raw images from the sky camera and masked images of the sky.

Columns and Units

1. DATE (MM/DD/YYYY): The date of the data point (in MM/DD/YYYY format).
2. MST: The time in Mountain Standard Time (MST), represented in HH:MM format.
3. Global Horizontal [W/m^2]: The total solar irradiance on a horizontal surface, measured in watts per square meter (W/m²).
4. Direct Normal [W/m^2]: The direct solar irradiance incident on a surface perpendicular to the sun's rays, measured in watts per square meter (W/m²).
5. Diffuse Horizontal [W/m^2]: The portion of solar irradiance scattered by the atmosphere that reaches a horizontal surface, measured in watts per square meter (W/m²).
6. Air Temperature [deg C]: The ambient air temperature, measured in degrees Celsius (°C).
7. Rel Humidity [%]: The relative humidity of the air, expressed as a percentage (%).
8. Avg Wind Speed @ 19ft [m/s]: The average wind speed at a height of 19 feet, measured in meters per second (m/s).
9. Avg Wind Direction @ 19ft [deg from N]: The average wind direction at 19 feet, measured in degrees from north (°).
10. Pressure [mBar]: The atmospheric pressure, measured in millibars (mBar).
11. Precipitation (Accumulated) [mm]: The accumulated precipitation in millimeters (mm).
12. Zenith Angle [degrees]: The angle between the sun and the vertical, measured in degrees (°).
13. Azimuth Angle [degrees]: The angle of the sun relative to the north direction on the horizontal plane, measured in degrees (°).
14. raw_images: Raw images captured by the sky camera at the corresponding time.
15. processed_images: Processed(masked) images that are used for further analysis in solar irradiance forecasting.
