The GOES-R Solar UltraViolet Imager

Abstract

The four Solar UltraViolet Imagers on board the GOES-16 and GOES-17 and the upcoming GOES-T and GOES-U weather satellites serve as NOAA's operational solar coronal imagers. These four identically designed solar EUV instruments are similar in design and capability to the SDO-AIA suite of solar telescopes, and are planned to operationally span two solar cycles or more, from 2017 through 2040. We present the concept of operations for the SUVI instruments, operational requirements, and constraints. The reader is also introduced to the instrument design, testing, and performance characteristics. Finally, the various data products are described along with their potential utility to the operational user or researcher.

Modeling Solar Eclipses at Extreme Ultra Violet Wavelengths and the Effects of Nonuniform Eclipse Shadow on the Ionosphere‐Thermosphere System

“…The SDO AIA provides (4,096 × 4,096 pixels) images of solar emissions at seven EUV wavelengths (94, 131, 171, 193, 211, 304, 335 A), where 10 A (Å ngstrom) = 1 nm, at sub‐minute resolution per wavelength (Lemen et al., 2012). Another space‐based EUV solar telescope is on‐board GOES‐R series satellites 16 and 17 providing EUV images at 6 EUV wavelengths with the SUVI (94, 131, 171, 195, 284, and 304 A) with data available since 2016 (GOES‐R 16) and 2018 (GOES‐R 17) (Darnel et al., 2022). The SUVI images have a resolution of 1,280 × 1,280 pixels with a 4‐min cadence.…”
