Both ER2 and Citation flew an Aqua underflight mission centered at the easten tip of Cape Cod. The orbit time is 17:41 GMT. After the overpass time, the ER2 flew northward from Cape Cod to just east of the James Bay, then retured to Bangor. After the orbit, the citation did winter storm recon in the region off the NJ coast and south of the CT/RI/MA coast with dropsondes spaced 50nmi apart. This coincided with the time of a developing winter storm. The mission was in support of ATReC and satellite verification. The Citation took off from Bangor 1651Z and released a series of six dropsondes along a line between (N42:42, W69:53) and (N41:02, W69:14). The Citation then turned to the northeast and dropped three more sondes between (N40:08, N72:29) and (N40:17, W73:00). All the sondes were released from 33,000 ft and took place between the times of 1736Z and 1909Z. The aircraft was in thin cloud throughout the flight with the exception of takeoff and landing. The cloud was composed of ice crystals, the types and sizes varying along the path.
