Local Observations (Supersites)
This submodule characterizes the structures in and of interactions among clouds, aerosols, water vapor and precipitation with a vertical resolution comparable to the HD(CP)² model. These efforts are concentrated at the Supersites where the best available instrumentation allows for continuous high-resolution vertical proﬁling. Challenges are the exploitation of sensor synergies at a given site, the understanding and consideration of three dimensional effects in retrieval methods, and the development of the same products across the sites with the goal to evaluate the HD(CP)² simulations and to support cloud and precipitation parameterization development for climate models. The ensuing continuous ﬂow of standardized quality-controlled observations processed by a common 1DVAR retrieval methodology supplemented by several Value Added Products (VAP) will feed a data base optimally suited to derive multi-parameter statistics for parameterization development and to interrogate processes like cloud formation, entrainment, and precipitation initiation and formation.
