Overview

ATM_PRESSURE defines whether to include or not an reference level pressure field.

Usage

mslp, or both (though only one will actually be used). The new property can an ASCII file, a constant value, an HDF file, ...

  • That's it!

Syntax

Describe here the correct syntax of the keyword in the configuration files:

ATM_PRESSURE : VALUE

Where value can be

  • 0 i.e. no reference level pressure field to be used,
  • 1 i.e. use a reference level pressure field defined in module Atmosphere.

Type

ATM_PRESSURE is a logical/boolean parameter.

Default value

By default, no atmospheric pressure will used:

ATM_PRESSURE : 0

Modules

Here are the modules where the keyword is supposed to be inserted:

Sample

Snippet taken from the module Hydrodynamic configuration file:

ATM_PRESSURE            : 1
ATM_PRESSURE_TYPE       : 2
WIND                    : 2
WIND_SMOOTH_PERIOD      : 432000.
RAMP                    : 1
INERTIAL_PERIODS        : 6

INITIAL_ELEVATION       : 1
INITIAL_ELEVATION_VALUE : 2.08

Snippets taken from the module Atmosphere configuration file:

<beginproperty>

UNITS                   : Pa
DESCRIPTION             : Meteo-IST MM5 atmospheric pressure
DEFAULTVALUE            : 0.
FILE_IN_TIME            : HDF
FILENAME                : ../../GeneralData/MM5/Portugal/MM5_20060729_Portugal.hdf5

<endproperty>
<beginproperty>
NAME                    : mslp
UNITS                   : Pa
DESCRIPTION             : Meteo-IST MM5 mean sea-level pressure
DEFAULTVALUE            : 0.
FILE_IN_TIME            : HDF

NOTE: Only one of the above properties will actually be used. They were written both for illustrative purposes only.
