DATA SET OVERVIEW: Introduction or abstract: Model outputs correspond to the SALLJEX experiment,using the Fifth-generation Penn State/NCAR Mesoscale Model (MM5), version 3-5.The following main physical parametrizations are used in the simulations presented in this work. High-resolution planetary boundary layer (Blackadar 1976), Cumulus convection Kain- Fritsch (1993), Explicit moisture scheme (simple ice) (Duhia 1989), Cloud-radiation (Benjamin and Carlson 1986), OSU -LSM Time period covered by the data: Initial Time 17 00 UTC, Final Time 19 00 UTC (January 2003) Physical location (including lat/lon/elev) of the measurement or platform ............................................................................................................................................................................................................ **** EXPERIMENT 1 **** This resolution corresponds to the required resolution of 80 km. lat ( 60 S - 10 N ), lon (90 W - 30 W) STARTING DATE FOR THIS MM5V3 INPUT FILE IS 2003-01-17_00:00:00 MAXIMUM TIME = 2880. MINUTES TIME STEP = 140.00 SECONDS COARSE MESH DX = 80000.0 (METERS) GRID POINTS (X,Y) = ( 121,86 ) NUMBER OF LEVELS = 23 -----> sigma levels **** EXPERIMENT 2 **** This resolution corresponds to the required resolution of 20 km. lat (35 S - 10 S), lon (75 W - 45 W) STARTING DATE FOR THIS MM5V3 INPUT FILE IS 2003-01-17_00:00:00 MAXIMUM TIME = 2880. MINUTES TIME STEP = 60.00 SECONDS COARSE MESH DX = 20000.0 (METERS) GRID POINTS (X,Y) = ( 156,166 ) NUMBER OF LEVELS = 23 -------> sigma levels ................................................................................................................................................................................................................ Parametrizations IMPHYS = 4 SIMPLE ICE SCHEME (DUDHIA). ICUPA = 6 KAIN/FRITSCH CONVECTIVE PARAMETERIZATION SCHEME. IBLTYP = 2 BLACKADAR PBL IS USED. VERTICAL MIXING MOIST ADIABATIC IN CLOUDS. ISOIL = 2 FOR MULTI-LAYER SOIL TEMPERATURE MODEL OSU-LAND-SURFACE SCHEME. IMOIAV = 2 MOISTURE AVAIL WILL VARY IN TIME USING BUCKET MODEL, USING SOIL-MOISTURE CONVERTED VALUE TO START. IFRAD = 2 LONGWAVE AND SHORTWAVE SCHEMES (DUDHIA, 1989). THE RADIATION EFFECTS DUE TO CLOUDS ARE CONSIDERED. THE RADIATION IS COMPUTED EVERY 30 STEPS. ITPDIF = 1 HORIZONTAL DIFFUSION OF PERTURBATION TEMPERATURE. IVQADV = 1 VERTICAL MOISTURE ADVECTION USES LINEAR INTERPOLATION. IVTADV = 1 VERTICAL TEMPERATURE ADVECTION USES LINEAR INTERPOLATION. ITHADV = 1 POTENTIAL TEMPERATURE ADVECTION USED ICOR3D = 1 FULL 3D CORIOLIS FORCE. IFUPR = 1 UPPER RADIATIVE BOUNDARY CONDITION. IBOUDY = 3 RELAXATION I/O BOUNDARY CONDITIONS ARE USED. ..............................................................................................................................................................................................................
