 ===== Calibration ===== ===== Calibration =====
  
-This is where we will put the steps to calibrate the UWyo instruments when they are known+In order to calibrate the instrument, we need to have the CPC concentrations and the photo detector voltages in the same file. 
 +First, use the "convert_cpc3771tonasa" script on the text file. This will create a CPC raw file that we can work with. 
 + 
 +Since the CPC data is 1Hz and the UWyo is every 30 seconds we will next need to average the CPC file for every 30 seconds. Within the CPC directory use the "avgfields" script with points set to 30 for a 30 sec average. No need to fill in any of the other fields. Input file will be the CPC raw file and the output file should be in the form of "CPC3771_YYMMDDavg30sec.raw".  
 + 
 +Since the CPC and UWyo were probably not turned on at the exact same time it is important to find what time the CPC and UWyo started and stopped recording. The UWyo data we are using in this is the file with the format "YY_MM_DD_HH_MM_SS.ccn2_conc.raw" in the PostProcessing directory. It may be necessary to use the "subset" script at this point on one of the files to match the start times up to within 15 seconds. This is so we can successfully merge the files later. When using subset only the start and end times must be filled in. The field section can be filled in to get rid of unnecessary parameters. Input file is avg30sec file and the output file from subset should be in the form of "CPC3771_YYMMDDavg30sec_subset.raw".  
 + 
 +Finally within the PostProcessing directory we will need to use the "mergefield" script to merge our CPC3771_YYMMDDavg30sec_subset.raw file with the YY_MM_DD_HH_MM_SS.ccn2_conc.raw file. The mergefield command should take on this form: 
 + 
 +mergefield field=1,2,3,4 target=5,6,7,8 tolerance=15 file=14_11_11_15_52_27.ccn2_conc.raw </path to CPC file/CPC3771_141111avg30sec_subset.raw> 14_11_11_15_52_27.CPC_CCN_ratios.raw 
 + 
 +This leaves us with a file containing the UWyo photo detector voltages and the CPC concentrations.  
 + 
 +More steps will be added on how to calibrate beyond this point at a later time.
