In RAOBman, click to | Open RAOB button | to open the MISSSION_RAOBs.RAOB2 file (HIPPO-3_RAOBs.RAOB2 in this example)
To speed up the process of finding a particular RAOB to use as a
template, go to the RAOBman
| Filters tab | and enter the
RAOB WMO name in the | Site
frame | text box
Click the | Add button | to
add it to the |Site frame
| combo box list. (The only one in this case.)
Enable the site filter by clicking the enable text box in the upper
left hand corner turning it from red to green
Switch to the RAOBman | Select tab |
On the | Select tab | click
the | Search button | to load
all the DNR soundings in the MISSION_RAOBs.RAOB2
file.
Go down the | Select list box | to the sounding that you want to use as
the template (DNR 2010-03-15-12UT in this example)
Click the RAOBman | Select tab | Save Ref button | to specify this as
the reference RAOB for the template file
This will automatically disable the RAOBman
| Filter tab | Site frame | enable text box and
clear the site list
It will then automatically clear the RAOBman
| Select tab | and reload all
the soundings in the MISSION_RAOBs.RAOB2
file
Now set the RAOBman | Select tab | RMS text box | to a value that
assures that 150-200 RAOBs will be found to be within this RMS of the
reference/template profile
When we did this with 3.0 K only 44 RAOBs were found to match the
template profile. Therefore the value was increased to 4.0 K as shown
above.
After setting this value, click the RAOBman | Select tab | RMS button.
165 soundings were found on this second pass and save automatically in
the DNR___2010031612.RAOB2
file in the \MISSION\RAOB\Templates\
folder
Note that the RAOBman | Select tab | RMS Zp Range (km) frame | can be
used to restrict the altitude range over which the RMS is calculated.
This can be very useful when trying to get get good templates over a
restricted range of the atmosphere such as near the tropopause where
there may be particular structure that needs to captured.
