, precipitation data were not saved in these hindcasts.) EC-IFS Cy31r1 was operational between 12 September 2006 and 5 June 2007; it is also the version used in the interim reanalysis and the current seasonal forecasting system at ECMWF ( Bechtold et al. 2008 ). The data assimilation system of the IFS uses a four-dimensional variational analysis approach with a 12-h assimilation window ( Rabier et al. 1998 ). This employs simplified physics in the tangent linear model ( Mahfouf 1999 ; Janiskova et al. 2002

some technical details about the objective data analysis of TWP-ICE observations to help users better understand the large-scale state dataset developed from this study. The TWP-ICE sounding array ( Fig. 1 ) provided three hourly soundings during the intensive operational period (IOP) from 22 January to 12 February 2006. The array contains four mainland stations (including the ARM Darwin site), one station on the Tiwi Islands, and one station on the Australian Commonwealth Scientific and Industrial

, 2007) . Briefly, HERB synthesizes ice cloud microphysical property information from VIRS; liquid cloud properties, precipitation profiles, SST, and water vapor retrievals from the TRMM TMI; and vertical profiles of temperature and humidity from the European Center for Medium-Range Weather Forecasts (ECMWF) reanalyses to characterize the three-dimensional structure of clouds and precipitation in the atmosphere. These provide input to a broadband radiative transfer model that simulates vertical
