NOAA GOES-R Series Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) Instrument Calibration Data

The EXIS Instrument Engineering Telemetry Data file contains data used to support the generation of EUVS and XRS Level 1b products, and monitor and evaluate the health and performance of the sensor suite. This data is transmitted to the ground in raw digital counts, and subsequently converted into physical units by the ground system. Some of the data pertains to the temperature of components in the sensor suite. This includes temperatures for the power board, interface board, operational heater, entrance slit, detectors, detector boards, microprocessor board, EUVS-C analog to digital converter, and XRS ASICs and other sub-assemblies. Other telemetry includes XRS-A and XRS-B solar minimum and maximum dark current and field of view corrections, and gains. Temperatures are expressed in units of kelvin, and the other telemetry items are in units of counts, counts per digital number, or have no units of measure. A netCDF-4 file containing this EXIS engineering telemetry is generated hourly. Telemetry parameter values are included at one second intervals, and summary statistics, including minimum, maximum, mean and standard deviation, are produced for the one hour period.
