Description
This study investigates the photospheric and chromospheric flow field in active region NOAA 13096, which consists of pores, sunspots with partial penumbrae, and light bridges. The improved High-resolution Fast Imager (HiFI+) and GREGOR Infrared Spectrograph (GRIS) acquired high-resolution data at the 1.5-meter GREGOR solar telescope at Observatorio del Teide, Izaña, Tenerife, Spain. The Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO) complements the GREGOR data with synoptic full-disk continuum images and line-of-sight (LOS) magnetograms. Background-Subtracted Activity Maps (BaSAMs) were used to locate areas with enhanced activity, for which Local Correlation Tracking (LCT) provides horizontal proper motions and GRIS LOS velocities and full-Stokes polarimetry. We present first results of the three-dimensional photospheric and chromospheric flow and magnetic fields scrutinizing the (inverse) Evershed effect in a complex active region.
