For much of its life, the center was not well defined, and the wind center was displaced from the pressure center. This makes the center finding algorithm unreliable, hence the partition of the wind near the center into its radial and tangential components unreliable as well. This is particularly the case with the flights on the 30th. Use the data at your own risk, and with great circumspection. The dewpoint data from the 28U3, 30U1, 31U2 and 04U1 flights are extremely suspect. These dewpoint data have been replaced with no-data flags. The liquid water measurements for the 28H1 flight look wrong - apparently the instrument was non-functional during this flight. - ER
