For the past two and a half months, we have been measuring greenhouse gases around Fairbanks in the AMIGGO campaign. This is Niki Jacob’s project, and we had great collaboration with Qiansi Tu and Harrison Parker in Fairbanks and Dubey, Frank, and Thomas from afar. It was great also to work with Greg Osterman of JPL, the OCO-2 validation team leader on making coincident observations of that satellite’s measurements with our ground-based observations. It has been great to get out and about in the area and watch the summer transition into fall. I leave you with a photo of Denali on the way down to the Nenana site today.
