Small-Scale Structure Of Stratocumulus Top - Glimpse Into The High Resolution Data Collected During POST

Physics of Stratocumulus Top (POST), a research campaign focused on a detailed study of processes occurring in the uppermost part of Sc cloud and capping Entrainment Interfacial Layer (EIL) was held in the vicinity of Monterey Bay in July and August 2008. The CIRPAS Twin Otter research aircraft, equipped to measure thermodynamics, microphysics, dynamics and radiation, collected unique data characterizing the cloud top region. Among them there are 1000 Hz (~5 cm spatial resolution) records of fluctuations of temperature from the Ultra Fast Thermometer (UFT) and of liquid water content (LWC) from the Particulate Volume Monitor (PVM). Selected examples of these records, showing correlated and uncorrelated fluctuations of temperature and LWC, will be presented and discussed.
