Solar X-ray and Extreme Ultraviolet Irradiance Data from GOES-R Satellites

EXIS instrument data measures solar soft X-ray irradiance and solar extreme ultraviolet spectral irradiance in the 5-127 nm range. The dataset is produced by NOAA's National Centers for Environmental Information (NCEI) for the GOES-R series satellites. The information is used to monitor solar flares and variations affecting space weather and Earth's atmosphere.

Use Cases

• Correlate solar X-ray irradiance measurements with radio blackout events and GPS navigation errors.
• Model satellite drag and orbital decay using time-series data of extreme ultraviolet spectral irradiance.
• Predict the onset and intensity of solar flares from soft X-ray irradiance sensor readings.
• Analyze the impact of solar variations on high-frequency (HF) radio communications and power grid operations.

Strengths

• Measures solar irradiance across a specific 5-127 nm wavelength range.
• Data is critical for operational space weather forecasting and impact assessment.

Limitations

• Specific row count, temporal coverage, and calibration update frequency are unknown.
• Data accessibility and required preprocessing steps for the raw instrument data are not detailed.
