Overview

ATM_PRESSURE_TYPE defines the type of Atmospheric pressure field to include. It allows currently allows two flavours: Atmospheric pressure and Mslp or Mean Sea-Level pressure.

Usage

mslp, or both (though only one will actually be used). The new property can be 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_TYPE : VALUE

Where value can be

  • 0 i.e. no atmospheric pressure to be used,
  • 1 i.e. use atmospheric pressure in the module Atmosphere configuration,
  • 2 i.e. use mslp in the module Atmosphere configuration file;

Default value

By default, the atmospheric pressure field will used:

ATM_PRESSURE_TYPE : 1

Modules

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

Dependent keywords

Here's a list of mandatory keywords to use with the ATM_PRESSURE_TYPE keyword:

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>
NAME                    : atmospheric pressure
UNITS                   : Pa
DESCRIPTION             : Meteo-IST MM5 atmospheric pressure
DEFAULTVALUE            : 0.
FILE_IN_TIME            : HDF
FILENAME                : ../../GeneralData/MM5/Portugal/MM5_20060729_Portugal.hdf5
OUTPUT_HDF              : 1
<endproperty>
<beginproperty>
NAME                    : mslp
UNITS                   : Pa
DESCRIPTION             : Meteo-IST MM5 mean sea-level pressure
DEFAULTVALUE            : 0.
FILE_IN_TIME            : HDF
FILENAME                : ../../GeneralData/MM5/Portugal/MM5_20060729_Portugal.hdf5
OUTPUT_HDF              : 1
<endproperty>

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