Abstract: Multi-transition molecular line observations have given us a good indication of the range of physical conditions in dense cloud cores around massive protostars. There is little information, however, about conditions in the surrounding Giant Molecular Clouds, on scales 5-25 pc, where the bulk of the molecular material resides. We present large scale CO multitransition observations of NGC 7538. Using large velocity gradient (LVG) modeling, we derive estimates of pressure and temperature.
