Project ECCRO

An intensive reconnaissance expedition, involving the use of multilevel aircraft flights and special radiosonde ascents, was carried out over the eastern Caribbean during a relatively quiescent period in October 1965. This paper contains, first, an outline of the type of instrumentation used and the methods applied in reducing, correcting, and analyzing the data. Next, sample analyses are presented for each of the five levels and for 1 of the 6 days of the project, showing the distribution of winds, geopolitical heights, temperatures, mixing ratios, vertical velocities, and cloud patterns. Finally, a summary of the spatial variability of the various quantities is given with a discussion concerning the amount of uncertainty in the analyses.
