Twin Otter

In the Twin Otter campaigns in 2008 and 2009 we conducted our first AMAX-DOAS measurements. We placed a telescope into a pylon and mounted it to the exterior of the NOAA Twin Otter. All together about 20 flights over Colorado and California as well as transit flights were performed on which we measured NO2, CHOCHO and HCHO.
