Someone is up high, quite high in fact. That’s the ARO (Atmospheric Research Observatory) tower, a good spot for surveying the landscape. ARO is a National Science Foundation facility used in support of scientific research related to atmospheric phenomena. Its long-term research program measures trends of important trace gases and aerosols and investigates the influence of these gases and aerosols on the Earth’s climate. They aren’t measuring gases inside the South Pole station’s greenhouse, but look what’s going on in there—lots of growth. What a difference two weeks make.
