#####
Go to the **"Submesoscale"** `wiki`_ and click on "useful links" under **Outils**, then "WERA HF Radar Software - Fortran Programs Documentation". Here we find which Fortran program we need to use to do what we want.
We need to "remove wrong calibration data and apply new ones", so we need to use Modify_WERA_SORT.
Steps to generate new calibration file
*****************************************
#. loggin to the wera server wera@132.215.11.14
#. cd etc/
In this folder, we find the original calibration files:
- calibration_pab.wera
- calibration_pao.wera
If we look at what the content of the calibration file:
- cat calibration_pab.wera
the phase is given in the 3rd column.
On 2014-10-29 (PAO) and 2014_10-30 (PAB), calibrations were undertaken in the field.
Calibration data are stored in:
- /hfr-data-processing/calibrations/PAB/2014303 every minute from 16:53 to 17:55
- /hfr-data-processing/calibrations/PAO/2014302 every minute from 17:46 to 18:23
While the calibrations were running, tracks were recorded with an instrument belonging to Helzel (PAO and PAB) as well as with an instrument belonging to Flament (PAB). So for PAB we are going to be able to compare the two.
For the all month of September 2013, we are going to generate new files using the new calibration phases.
Post-processing of WERA radial currents is documented `here`_.
.. _here: WERAprocessing.html
For example, let us see what we have to do to generate radial currents at PAO using the new calibration phases for september 1st, 2013 (Julian day 244):
Data in the ~/data1/PAO/2013244/raw/ folder are converted in .SORT and .RFI in the ~/data1/PAO/2013244/results/ folder using the **do_process_SORT_pol** shell script. These files are generated using the "original" calibration phases.
First we need to change the original .SORT and .RFI files and save them to .SORT0 and .RFI0 to save them for future reference. This is done with the shell script **changeName.sh** located in /hfr-data-processing/postprocessing/wera/.
.SORT====> .SORT0 (generated with original calibration)
.RFI ====> .RFI0
as well as 2 symbolic links to point towards which file is the calibration to remove (with link calibration.wera.remove) and which file is the calibration to use (with link calibration.wera.apply).
If we look at what the content of the calibration file is:
* cat calibration_pab.wera
We want to compare the value of the phase given in the 3rd column with the one that we compute.
