Description
GOES-16 EXIS/XRS science-quality Level 2 1-minute average X-ray irradiance (avg1m) product in daily NetCDF-4 files. The product provides one-minute averages of corrected primary-channel and individual-detector XRS-A (0.05-0.4 nm) and XRS-B (0.1-0.8 nm) fluxes, along with uncorrected observed fluxes and estimated electron contamination contributions. It includes the number of valid samples contributing to each average, quality flags and flags for excluded samples, primary channel information, corrected XRS-B2 quadrant currents, electron-correction status and spacecraft ancillary data. This science-quality Level 2 product is generated using retrospectively reprocessed data and updated calibrations and corrections, separately from the operational Level 2 series used for space-weather operations. NOAA recommends science-quality Level 2 XRS products for scientific analysis. Consult the XRS Level 2 ReadMe and User Guide for details.

XRS-A primary average flux
ParameterKey
xrsa_flux
Description
One-minute average solar X-ray irradiance in the XRS-A band (0.05-0.4 nm), using the XRS-A primary-channel merged signal. Electron contamination estimated using GOES SEISS/MPS-HI has been subtracted: xrsa_flux = xrsa_flux_observed - xrsa_flux_electrons. The flux is at the spacecraft and has not been normalized to 1 AU; multiply by au_factor for the equivalent irradiance at 1 AU.

Possible conditions include eclipse, particle spike, calibration, off-pointing, temperature and data-quality errors, invalid mode, missing data, and Level 0 error. Consult NetCDF flag_masks and flag_meanings.

Name
Flags for electron contamination correction
ParameterKey
electron_correction_flag
Description
Bit-field status of the GOES SEISS/MPS-HI-based electron contamination correction. The electron correction is valid when its status bit indicates 0 and invalid when the invalid-status bit is set (value 1). The interpolation flag (value 2) indicates short gaps in SEISS/MPS-HI data. The decay flag (value 4) indicates the correction is smoothly turned off over approximately 2 hours when SEISS/MPS-HI data are missing and a future value is unavailable; the correction is marked invalid after 1 hour of decay. Channel-specific significance flags (values 8, 16, 32, 64, 128, and 256 for XRS-A, XRS-B, A1, A2, B1, and B2, respectively) indicate that the estimated electron contamination exceeds 50% of the observed signal. Interpret combined flags using NetCDF flag_masks, flag_values, and flag_meanings.
