We present high-angular-resolution (≲0.″1 to ≈0.″2, ≈15-30 au) observations of CO, 13CO, and C18O in either or both J = 2-1 and J = 3-2 lines in the transition disks around DM Tau, Sz 91, LkCa 15, and HD 34282. We derived line emission surfaces in CO for all disks and in 13CO for the DM Tau and LkCa 15 disks. With these observations, we do not resolve the vertical structure of C18O in any disk, which is instead consistent with C18O emission originating from the midplane. Both the J = 2-1 and J = 3-2 lines show similar heights.
