Overview
ATM_PRESSURE defines whether to include or not an reference level pressure field.
Usage
- Activate Atmospheric pressure keyword in the module Hydrodynamic,
- Active ATM_PRESSURE_TYPE keyword in the module Hydrodynamic,
- Include a new property in the module Atmosphere called atmospheric pressure or
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:

Dependent keywords
Here's a list of mandatory keywords to use with the ATM_PRESSURE 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.
