SUMMARY:What makes the solar chromosphere so interesting?
DESCRIPTION:What makes the solar chromosphere so interesting?\nProf. Mats C
 arlsson\n\nMagnetic fields break through the solar surface in a hierarchy 
 of magnetic elements ranging from Earth-sized sunspots down to tiny concen
 trations that are barely resolved in the highest-resolution photospheric i
 mages. In the chromosphere they combine in intricate, highly dynamic, and 
 continuously evolving fibrilar patterns. Movements of the photospheric fie
 ld-line footpoints drive, guide, and control the flows of energy and mass 
 into the corona, and trigger energy-releasing magnetic reconnection throug
 h relentless topological rearrangement. The conversion from convectively d
 riven footpoint motion to outer-atmosphere outflows and loading takes plac
 e in the dynamic, fine-structured chromosphere.\nA number of important fac
 ilities for observing the solar chromosphere have recently come on line (e
 .g. the SDO and IRIS satellites and ground-based Fabry-Perot interferomete
 rs) or will become operational in the near future (e.g. DKIST). The overwh
 elming complexity of the chromosphere makes it necessary to have numerical
  simulations for the interpretation of the observations. Such realistic si
 mulations, spanning the solar atmosphere from the convection zone to the c
 orona, are now becoming feasible.\nThis presentation will introduce the fa
 scinating aspects of chromospheric physics and review recent results from 
 both observations and numerical simulations.
