Spatially resolved net radiative losses in the chromosphere of an emerging-flux region (bottom), a context Ha image (middle), and the line-of-sight component of the photospheric magnetic field (top). The red box indicates the FOV used to calculate the radiative losses. The observations were acquired at the SST in the Ca II K line, Ca II 854 nm, Fe I 630.1, and 630.2 nm and in the Ha line with the CRISP and CHROMIS instruments. Adapted from Díaz Baso et al. (2021).
