The Barnes IT-2 radiometer failed only moments after crossing the coastline just north of the Cape and could not be repaired aboard the plane. On the other hand, the infrared hygrometer on the Navy plane mal- functioned shortly after takeoff and its ailment was not diagnosed until the Constellation returned to its home base at Patuxent River, Md. The Navy plane has a backup system for humidity measurements—part of the AMQ-17 system described earlier—but it was not opera- tional that day. Thus, no humidity measurements were obtained by this group. The RFF had no backup IR unit for its aircraft and thus sea surface temperatures were not obtained by that group. Comparisons of certain aircraft sensors with an early version of SAIL's boundary layer instrument package and of the Navy ART and Peirce bucket sea surface tempera- tures are shown in the table. Here, plane-to-plane compari- sons of air temperature are excellent and plane-to-boundary layer package comparisons are reasonably good for the Navy's 1,000-ft. passes and very good for the 500-ft. passes of both airplanes. The humidity data are not too comparable, and the fluctuations by the amounts shown for the boundary layer package for the 1-min. intervals between measurements indicate that part of the difference may have been a result of relative humidity measuremen
