Data Processing

Both files were created from the original dataset by:

1. Filtering stations to include only those within the Georgia Tech campus boundary (obtained from OpenStreetMap)
2. Removing unnecessary columns (azimuth_sin, azimuth_cos, hour, hour_sin, hour_cos, day_of_year, doy_sin, doy_cos)

The 16-station file (gatech_16_stations_10_min_long_format_sun_angles.csv) was further processed by removing two stations (10884521 and 10884524) that may have had incomplete data coverage or were not needed for specific analyses.

Usage Recommendations

• Use gatech_10_min_long_format_sun_angles.csv if you need the complete dataset with all available stations within the campus boundary.
• Use gatech_16_stations_10_min_long_format_sun_angles.csv if you need a more consistent dataset with only the 16 core stations that have better data coverage.
