Set Temporal Domain

When you perform a simulation of the atmosphere you are creating a 
weather forecast.   Even if you are simulating an historic event, you are 
still starting with the atmosphere in some state and evolving it in time to 
an end state.  The Set Temporal Domain dialog box is the mechanism used to 
set the time bounds on your simulation.

The first setting in the OMEGA Settings Column is "Set Temporal Domain".  This 
placement reflects the idea that the time bounds of an OMEGA simulation are 
the most fundamental part.  You must first decide -when- and -how long- your
simulation will be before you can set other parameters.  When the button is 
pressed the Set Temporal Domain dialog box is popped up.

This dialog box is one of the easiest dialogs to use.  The dialog consists of 
two sections: Temporal Settings and Action Buttons.  How to use each section 
will be described, followed by exact specifications of each control's actions, 
valid data range, and default value.

The data for each region is stored internally as both the times you input 
and the total length of time for the simulation.


Temporal Settings

This section has eight text entry boxes.  By clicking the first mouse button 
within the box you will be able to enter your choices.  The cursor location 
will shown by a blinking bar.  You may type as usual in the box to enter 
the desired Start and End times in broken-down form for your simulation.  

On most systems both backspace and delete will work to remove digits. 
Be sure to abide by the digit conventions listed in parenthesis beside 
the box when entering data.  

Start Year - Year of Start time in four digit form.
             Valid Range: 1900 to 2100
             Default Value: current year

Start Month - Month of Start time in two digit form.
              Valid Range: 1 to 12
              Default Value: current month

Start Day - Day of Start time in two digit form.
            Valid Range: 1 to 31
            Default Value: current day

Start Hour - Hour of Start time in four digit form.
             Valid Range: 00 to 23
             Default Value: 00

End Year - Year of Start time in four digit form.
           Valid Range: 1900 to 2100
           Default Value: current year + 24 hours

End Month - Month of Start time in two digit form.
            Valid Range: 1 to 12
            Default Value: current month + 24 hours

End Day - Day of Start time in two digit form.
          Valid Range: 1 to 31
          Default Value: current day + 24 hours

End Hour - Hour of Start time in four digit form.
           Valid Range: 00 to 23
           Default Value: 00


Action Buttons

Clear Form - This button will reset the text entries to blanks. 

Default -  This button will reset all text entries to their default values.

OK - This button will check the time data, cause XOMEGA to write out
     a "time.inp" file in the case directory, and close the dialog box. If 
     any values are in error, a Set Temporal Domain Error dialog box will pop 
     up alerting you of the specific errors and suggestions on how to 
     correct them.  See below for information on the Error dialog box.
     No "time.inp" file will be written if there are errors in the data.

Cancel - This button will decline the time data, reset the values to default,
         and close the dialog box.  There is no confirmation process.

Help - This button will open the Help dialog and load this section.


Set Temporal Domain Error

While entering values into the text entries if you make errors a dialog
box will pop up alerting you of the errors and suggesting ways to correct
them.  The top part of the dialog box contains the error message 
and the suggestions.  The bottom part has a row with two action buttons:

OK - This button will dismiss the Error dialog.

Help - This button will open the Help dialog and load this section.
