PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) The Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE), externally led by UW-Madison, will quantify the radiative processes effected by changing temperatures in the Arctic.
Tropospheric Ozone Lidar Network (TOLNet) The primary scientific objective is to provide time/height ozone measurements from near the surface to the top of the troposphere to describe in high-fidelity their spatio-temporal distribution.
