Recent high resolution observations of the solar atmosphere (e.g., with SDO, Hinode, SST, IRIS) provide new powerful diagnostics of the mechanisms responsible for heating the solar corona. I will discuss how these new observations have enabled significant advances in our understanding of coronal heating properties in active regions. I will especially focus on coordinated IRIS/SDO/SST active region observations of nanoflare heated AR core loops to showcase the diagnostics potential of high spatial, spectral, and temporal resolution chromospheric/transition region/coronal observations, when coupled with state-of-the-art (1D/3D) models.
