abstract = {Due to the major role of the sun in heating the earth's
surface, the atmospheric planetary boundary layer over land
is inherently marked by a diurnal cycle. The afternoon
transition, the period of the day that connects the daytime
dry convective boundary layer to the night-time stable
boundary layer, still has a number of unanswered scientific
questions. This phase of the diurnal cycle is challenging
from both modelling and observational perspectives: it is
transitory, most of the forcings are small or null and the
turbulence regime changes from fully convective, close to
homogeneous and isotropic, toward a more heterogeneous and
intermittent state.These issues motivated the BLLAST
(Boundary-Layer Late Afternoon and Sunset Turbulence) field
campaign that was conducted from 14 June to 8 July 2011 in
southern France, in an area of complex and heterogeneous
terrain. A wide range of instrumented platforms including
full-size aircraft, remotely piloted aircraft systems,
remote-sensing instruments, radiosoundings, tethered
balloons, surface flux stations and various meteorological
towers were deployed over different surface types. The
boundary layer, from the earth's surface to the free
troposphere, was probed during the entire day, with a focus
and intense observation periods that were conducted from
midday until sunset. The BLLAST field campaign also provided
an opportunity to test innovative measurement systems, such
as new miniaturized sensors, and a new technique for
frequent radiosoundings of the low troposphere.Twelve fair
weather days displaying various meteorological conditions
were extensively documented during the field experiment. The
boundary-layer growth varied from one day to another
depending on many contributions including stability,
advection, subsidence, the state of the previous day's
residual layer, as well as local, meso- or synoptic scale
conditions.Ground-based measurements combined with
tethered-balloon and airborne observations captured the
turbulence decay from the surface throughout the whole
boundary layer and documented the evolution of the
turbulence characteristic length scales during the
transition period.Closely integrated with the field
experiment, numerical studies are now underway with a
complete hierarchy of models to support the data
interpretation and improve the model representations.},
