SEVIRI ( Montmerle et al. 2007 ), and 80 km for IASI ( Guidard et al. 2011 ). In ARPEGE, the assimilation density is 139 km for ATOVS, 100 km for IASI, and 125 km for SEVIRI. b. The VarBC configurations in ALADIN We evaluate the performance of the VarBC-LAM and VarBC-global configurations in the framework of the limited-area model ALADIN. In VarBC-global, bias coefficients are adopted from the global model ARPEGE at each analysis time without any initialization period. To assure a consistent set of

modified version of an observing system simulation experiment (OSSE; Arnold and Dey 1986 ; Atlas 1997 ). In this type of experiment, a current or potential observing system can be simulated in a numerical model for the purposes of validating sampling strategies, model performance, and data assimilation techniques. The latter two of these examples are beyond the scope of this work, and our main focus is to evaluate the existing hurricane hunter sampling strategies. Uhlhorn and Nolan (2012) employed

be valuable for constructing and analyzing better models of MBL cloud and its sensitivity to environmental conditions. The Eulerian and Lagrangian samplings from CSET also provide valuable datasets for directly evaluating forecast models and general circulation models (GCMs) used in forecast mode. Based on this background, the following scientific goals were determined for CSET: Define the evolution of the cloud, precipitation, and aerosol fields in stratocumulus clouds as they transition into

the estimated inversion strength (EIS) ( Wood and Bretherton 2006 ) and aerosol concentration. Our third goal is to demonstrate the potential for comparing data from individual flights with observationally constrained global model simulations sampled along the flight tracks, to evaluate model performance in this challenging regime. This includes reanalysis, as well as climate model simulations with winds and temperature (but not humidity, clouds, and aerosol) nudged toward reanalysis. We attempt
