Description
The Interface Region Imaging Spectrograph (IRIS) provides unprecedented high spatial,
temporal and spectral resolution observations of the chromosphere and transition
region. Joint with Hinode (XRT and EIS), and SDO/AIA, these observations cover from
the upper photosphere to the corona. I will discuss how recent IRIS observations of
footpoints of hot active region loops in non-flaring conditions, coupled with
detailed HD and MHD modeling including chromosphere, transition region and corona,
provide tight constraints on the mechanisms of energy transport and heating of the
plasma to coronal temperatures.
