NOAA GOES-R Series Solar Ultraviolet Imager (SUVI) Instrument Calibration Data

The Solar Ultraviolet Imager (SUVI) Instrument Engineering Telemetry Data file contains data used to support the generation of SUVI Level 1b products, and monitor and evaluate the health and performance of the instrument. This data is transmitted to the ground in raw digital counts, and subsequently converted into physical units by the ground system. Most of the data pertains to the temperature of components in the instrument. This includes temperatures for the guide telescope, door mechanism, supporting structure, shutter, aperture, filter wheels, mirrors, electronics, and CCD. CCD bias voltages are also included.
The SUVI Dark Frame Data file contains an image produced by the SUVI with the camera’s shutter closed. A dark frame measures the inherent bias and noise in the camera electronics, and is used to identify, track, and monitor permanently bad pixels. Dark frames are collected in the operational imaging epoch of the SUVI, and support the radiometric correction of the solar imagery products. Up to ten dark frames are used to support of radiometrically correcting individual solar images.
The SUVI Miscellaneous Frame Data file contains a special image produced by the SUVI to support several calibration related activities. Specific types of images include glass, flat-field, and light transfer curve.
