Hi folks -

This will be our last summary. This has been a very successful cruise. The instrumentation present during this leg held up, and the boat and crew served us well. We sampled a variety of conditions, and at least 4 collaborations w/ aircraft hold future promise. Thanks to all of you for your efforts in concocting this experiment.

Regards,
Paquita

SJ daily summary 1/24

Instrumentation: all working
aircraft in vicinity: C130, KingAir, UKMet boat location: NNE of Barbuda, slightly east of previous

Day highlight occurred between 1245 and 1330, during which the shipboard lidar & noaak radar, and the C130 & Wyoming King Air all sampled the same vigorous convective cell.

Winds calm and predominantly from the south. Cu convxn, when it occurs, is more vertically developed than yesterday. Noaak radar and lidar on at 9Z, hoping to catch some early-morning precip, but no such luck. A convective cell developed to our portside that attracted the C130 and King Air at about 13Z. We swung around and sampled it on the noaak&lidar in its fully developed and dissipating stage - 2 vertical km of 30 dBZ -, also some coincident data w/ the 2 aircraft if we're lucky. At 1320Z we may have coincident radar scans with the King Air. Aircraft and radar worked the same cloud up to approximately 1330, after which the aircraft left for more promise to the SE.

Another coincident sampling by ship & C130 of a much smaller cloud at ~ 1415. Beginning at 17Z we more or less we tracked due west north of Barbuda, which is now the lee side given the southerly winds. Radar and lidar off at 18Z, experiment ended for us at 0Z on 1/25, 8pmLT.
