OCO-2 overpass observations

We got the new shelter for the EM27/Sun spectrometer operating and observed greenhouse gas amounts over Fairbanks while the OCO-2 satellite also observed our location in target mode.   In this project, Niki Jacobs is working with NASA-JPL colleagues to compare these satellite observations to our ground-based observations.  The new shelter for the instrument should make observations easier and thus allow more frequent data collection.
