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.
