SDO is designed to help us understand the Sun's influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.

The Atmospheric Imaging Assembly (AIA) for the Solar Dynamics Observatory (SDO) is designed to provide an unprecedented view of the solar corona, taking images that span at least 1.3 solar diameters in multiple wavelengths nearly simultaneously, at a resolution of about 1 arcsec and at a cadence of 10 seconds or better.

2011年6月2日 · The AIA was launched as a part of NASA’s Solar Dynamics Observatory (SDO) mission on 11 February 2010. AIA will advance our understanding of the mechanisms of solar variability and of how the Sun’s energy is stored and released into the heliosphere and geospace.

5 天之前 · AIA is a coordinated effort led by the Lockheed Martin Solar and Astrophysics Laboratory (LMSAL) with the Smithsonian Astrophysical Observatory (SAO) as the major subcontractor, responsible for building the telescope assemblies and for assistance with calibration, data handling, and interpretation.

In the following sections, we will describe how to install or upgrade SSW for use with SDO data (Section 5.1), and the how to use SSW to interface with the HEK (Section 5.2) and to get HMI or AIA image data from the JSOC (Section 5.3).

SDO's Atmospheric Imaging Assembly (AIA) captures a shot of the sun every 12 seconds in 10 different wavelengths. The images shown here are based on a wavelength of 171 Angstroms, which is in the extreme ultraviolet range and shows solar material at around 600,000 Kelvin.

2021年8月29日 · 大气成像组件（Atmospheric Imaging Assembly，AIA） 以多种波长对太阳大气进行成像（每10秒可以拍摄10个波长的太阳图像），将表面变化与内部变化联系起来。 原理就是不同波长对应不同温度，不同温度对应着太阳大气中不容的高度， 这篇文章 中有说到。 SDO 的 AIA 仪器（右图）的图像分辨率是STEREO（中图）的两倍，成像分辨率是SOHO（左图）的 4 倍。 极紫外实验（Extreme Ultraviolet Variability Experiment，EVE） 以前所未有的光谱分辨率 …

The Atmospheric Imaging Assembly (AIA) provides multiple simultaneous high-resolution full-disk images of the corona and transition region up to 0.5 R above the solar limb with 1.5-arcsec spatial resolution and 12-second temporal resolution. The AIA con-sists of four telescopes that employ normal-incidence, multilayer-coated optics to provide

2022年1月6日 · The Atmospheric Imaging Assembly (AIA) instrument onboard the NASA Solar Dynamics Observatory (SDO) spacecraft has observed the full- disk of the Sun, nearly continuously, for the last ten years. It is one of three instruments on SDO, along with the Helioseismic and Magnetic Imager (HMI) and the Extreme …

The Atmospheric Imaging Assembly AIA on SDO will provide revolutionary coverage of the entire visible solar hemisphere observed from photospheric to coronal temperatures at 1-arcsecond resolution with a characteristic cadence of 10 seconds for each channel The AIA comprises four dual normal-incidence telescopes that enable it to cycle through a ...
