Lamont colocation Sandrine

In this example,  TM5 is used to provide co-location criteria between GOSAT and TCCON total column measurements. The blue star is aTCCON site, the green circles are all GOSAT soundings in the vicinity, and the red circles are those that can be considered co-located, and are therefore used for validation. The color bar denotes the column-average CO2 concentration in ppm.
