The Three-mm Ultimate Mopra Milky Way Survey (ThrUMMS) maps the fourth Galactic quadrant (|b|<1.0°) with the J=1→0 lines of 12CO, 13CO, C18O, and CN near 112 GHz. It has a spatial resolution of ~1’ and a velocity resolution of 0.3 km/s. Its main science goals include understandings the neutral/molecular ISM connection, the physical state of Giant Molecular Clouds, and large-scale Galactic structure and kinematics. The link to the homepage of the ThrUMMS survey can be found here.
