A Publicly Available Multiobservatory Data Set of an Enhanced Network Patch from the Photosphere to the Corona
Warren, Harry P.; Savage, Sabrina; Kobelski, Adam R. +3 more
New instruments sensitive to chromospheric radiation at X-ray, UV, visible, IR, and submillimeter wavelengths have become available that significantly enhance our ability to understand the bidirectional flow of energy through the chromosphere. We describe the calibration, coalignment, initial results, and public release of a new data set combining…
Data-driven Model of Temporal Evolution of Solar Mg II h and k Profiles over the Solar Cycle
Heinzel, Petr; Gunár, Stanislav; Koza, Július +2 more
The solar radiation in the cores of the Mg II h and k spectral lines plays a significant role in the illumination of prominences, coronal mass ejections (CMEs), spicules, flare loops, and surges. Moreover, the radiation in these lines strongly correlates with solar magnetic activity and the ultraviolet solar spectral irradiance affecting the photo…
