Chromospheric lines (CaII, MgII, H-alpha) are observed with spectroscopes of IRIS and Hida/DST. The chromospheric temperature will be derived from CaII and MgII, and velocity field will be derived from H-alpha. On the other hand, photospheric magnetic fields under jets are observed with HINODE/SOT.;;Main Objective: Chromospheric jets and photospheric magnetic fields in plage regions Scientific Justification: The main purpose is spectroscopically revealing the role of chromospheric jets for the heating of plages by investigating time variation of chromospheric absorption lines around fine structures in plages.
