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

EXIS-INST-CAL-ENG

GOES-R satellite illustration

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.

Lineage Statement	These data were produced by the NOAA Office of Satellite and Product Operations (OSPO) and are archived at the NOAA National Centers for Environmental Information (NCEI).
Processor	DOC/NOAA/NESDIS/OSPO > Office of Satellite and Product Operations, NESDIS, NOAA, U.S. Department of Commerce
Processing Steps	Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS) front-end processing starts on the spacecraft where space packets are multiplexed placing multiple packets in each transfer frame. Forward error correction (FEC) coding (Low-Density Parity Check - LDPC) occurs and the packets are downlinked. The data is received, forward error correction decode is performed. In the event of an uncorrectable error the transfer frame is discarded. Error-free space packets are then extracted from the transfer frames. EXIS science data arrives at the ground system from the spacecraft in a compressed format. The data is decompressed then packaged for delivery to external interfaces.
