  IRAM operates two observatories - the 30-meter Telescope on Pico Veleta in
Spain and NOEMA, an interferometer of ten 15-meter antennas on Plateau de Bure
in France. Both observatories allow to observe at millimeter wavelengths. Here,
we aim at discussing the complementary between continuum observations with
NOEMA and NIKA2 at the 30m and their role at the cutting edge of research in
astronomy. In particular, we will review possible synergies of continuum
studies from nearby star forming regions to high redshift galaxies at
cosmological distances.
