DESCRIPTION:Speakers: Julius Koza (Astronomical Institute\, Slovak Academy
  of Sciences)\nThe solar radiation in the cores of the Mg II h & k spectra
 l lines strongly correlates with solar magnetic activity and global variat
 ions of magnetic fields with the solar cycle. This work provides a data-dr
 iven model of temporal evolution of the solar full-disk Mg II h & k profil
 es over the solar cycle. Based on selected 76 IRIS near-UV full-Sun mosaic
 s covering almost the full solar cycle 24\, we find the parameters of doub
 le-Gaussian fits of the disk-averaged Mg II h & k profiles and a model of 
 their temporal evolution parameterized by the Bremen composite Mg II index
 . The Markov Chain Monte Carlo algorithm implemented in the IDL toolkit So
 BAT is used in modeling and predicting temporal evolution of the Mg  II h 
 & k peak-to-center intensity ratio and the Bremen Mg II index. The relevan
 t full-disk Mg II h & k calibrated profiles with uncertainties and spectra
 l irradiances are provided as an online machine-readable table. To facilit
 ate utilization of the model corresponding routines\, written in IDL\, are
  made publicly available at GitHub.\n\nhttps://meetings.aip.de/event/24/co
