PP COLOBOC, Status Report | COSMO General meeting, 7-10 September 2009, Offenbach Bettems Jean-Marie (jean-marie.bettems [at] meteoswiss.ch) SMOSREX data SMOSREX (Surface Monitoring Of the Soil Reservoir EXperiment), has been in operation since January 2001 in Mauzac, near Toulouse in France. Continuous ground measurements of meteorological variables, soil moisture and temperature profiles have been taken over bare soil and a grass plot left fallow. Some data are made available by MeteoFrance: Dear ET member, Please find below the link to get local validation dataset from SMOSREX (near Toulouse) over a 3 year period: since we agreed in June to share observational datasets for common validations of our land surface schemes. This is a first step in that direction. If some of you have data that they could share, we could put them at the same location or think about what Jean-Marie suggested (to be hosted under the COLOBOC web site).

WP-3 Mixing height calculation. WP-4 Air quality assessment. WP-5 Mixing height as input for the retrieval of PM10 concentration. The aim of the BASE-ALFA project is to: 1. acquire a complete set of surface and atmospheric measurements during two intensive observing periods (1+1months) at San Pietro Capofiume in the middle of the Po Valley; 2. verify the capability of state-of-the-art methods to correctly simulate PBL height from observed parameters when compared to LIDAR observations assumed as benchmark; 3. verify the capability of diagnostic and prognostic models to correctly simulate the PBL heights. contacts and information

This indirectly allows to detect the growth of the mixed layer in the morning leading to a reliable estimate of the PBL height. From an initial data analysis it is evident the good correspondence between the strong vertical gradient in aerosol concentration (left) and the thermal inversion at the top of the PBL (right).

PP COLOBOC, Status Report | COSMO General meeting, 7-10 September 2009, Offenbach Bettems Jean-Marie (jean-marie.bettems [at] meteoswiss.ch) MODIS derived vegetation (1) Historical records of vegetation characteristics reveal a substantial inter-annual variability of the start of season, which may limit the usefulness of a climatology based data set. A framework has been developed by R.Stöckli et al., using a prognostic phenology model with parameters constraint by MODIS data, which can provide an offline gridded forecast of the vegetation characteristics taking into account the actual evolution of the weather [Stöckli 2008]. Basically a statistical approach is used, relying on an ensemble Kalman filter to define the optimal parameters of the phenology model, for a specified set of meteorological data predictor (e.g. from a NWP model). One different set of parameters is derived per type of vegetation.

PP COLOBOC, Status Report | COSMO General meeting, 7-10 September 2009, Offenbach Bettems Jean-Marie (jean-marie.bettems [at] meteoswiss.ch) MODIS derived vegetation (2) The proposed new action consists to compare the produced vegetation characteristics with the COSMO climatological information and to evaluate the impact of such an approach in the COSMO model (in particular on the surface fluxes). The CPU cost of the predictive model is neglectable. The framework to produce the vegetation characteristics is already installed and running at MeteoSwiss, and R. Stöckli is willing to contribute to this action.
