GOES-R Series Level 1b EXIS X-Ray Sensor (XRS) Science-Quality Products

Metadata Updated: May 5, 2023

The GOES-R Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS) X-Ray Sensor (XRS) Level 1b science-quality data contain 1-second cadence soft X-Ray irradiance measurements covering 0.05nm - 0.4nm (Channel A) and 0.1-0.8 nm (Channel B) integrated passbands. Each channel has two irradiance sensors to capture the full dynamic range of the solar X-Ray irradiance.

This science-quality dataset is produced by NOAA’s National Centers for Environmental Information (NCEI) and utilizes code provided by LASP, and differs from the L1b operational product used at the NOAA Space Weather Prediction Center (SWPC) in that it incorporates retrospective fixes for issues in the operational product and uses the most recent calibrations. The science-quality data have been reprocessed from the start of the mission to the present date. Both the science-quality and the operational data sets contain recovered data due to spurious dropouts.
