Abstract

We present HIFI observations of [CII] and high-J transitions of CO and HCO+ at positions in S140 and DR21. We use a clumpy PDR model to model and interpret the observed line intensities. The emission from both massive star forming regions can be reproduced by assuming a clumpy, 2-component PDR scenario.
