DWD’s fully automatic MOSMIX product optimizes and interprets the forecast calculations of the NWP models ICON (DWD) and IFS (ECMWF), combines these and calculates statistically optimized weather forecasts in terms of point forecasts (PFCs). Thus, statistically corrected, updated forecasts for the next ten days are calculated for about 5400 locations around the world. Most forecasting locations are spread over Germany and Europe. MOSMIX forecasts (PFCs) include nearly all common meteorological parameters measured by weather stations.

Within the framework of the Baikal Drilling Project (BDP), a 192 m long sediment core (BDP-96-1) was recovered from the Academician Ridge, a submerged topographic high between the North and Central Basins of Lake Baikal. Sedimentological, clay mineralogical and geochemical investigations were carried out on the core interval between 90 and 124 m depth, corresponding to ca. 2.4–3.4 Ma. The aim was to reconstruct the climatic and tectonic history of the continental region during the intensification of Northern Hemisphere glaciation in Late Pliocene time. A major climate change occurred in the Lake Baikal area at about 2.65 Ma. Enhanced physical weathering in the catchment, mirrored in the illite to smectite ratio, and temporarily reduced bioproduction in the lake, reflected by the diatom abundance, evidence a change towards a colder and more arid climate, probably associated with an intensification of the Siberian High.
Electron-microprobe analyses (Table 5) were completed on a selection of grains from 11 samples, with a CAMECA SX-50 instrument (University of Louvain-la-Neuve, Belgium), under an accelerating voltage of 15 kV and a probe current of 20 nA. The standards used were the Kabira graftonite (Fe, Mn, P; Fransolet, 1975), corundum (Al), olivine (Mg), wollastonite (Si), and willemite (Zn).
Cuttings were crushed in a tungsten carbide ball mill for 25 min; while core samples were crushed in a tungsten carbide jaw breaker and then processed in the same way as the chip material. The resulting powder samples (max 0.06 mm size) were dried at 105°C, 3 gr selected and mixed with 2.5% Moviol solution and finally pressed under 40 kN into alumina rings. These standardized pellets were used for both, XRD and XRF measurements. For the determination of major and trace elements a fully automated wavelenght-dispersive XRF device (SIEMENS SRS 303 AS) was used in the field laboratory. The standard measuring operation comprised 11 major elements (SiO2, TiO2, Al2O3, Fe2O3 total, MnO, MgO, CaO, Na2O, K2O, P2O5, S) and 12 traces (Rb, Sr, Y, Zr, Nb, Cr, Ni, Zn, V, Cu, Th, U). Element concentrations were calculated by setting up calibration curves computed with more than 40 international natural rock standards.
