1.0 General Description
Data set contains photolysis frequencies calculated from spectrally resolved 
actinic flux measurements taken using the GV HARP instrument during the 2012 
TORERO field campaign in Chile and Costa Rica.  Spectral data were collected on 
19 flights between 1/18/2012 and 2/29/2012.  Photolysis Frequencies were 
calculated from the actinic flux data using a modified version of the ACD TUV 
model.  

2.0 Data and Format Information
Data file is tab delimited ASCII formatted text.  There are 8 header lines with 
the 8th containing the reaction/variable names.  Missing Data Flag is -9999.

3.0 Quality Control Procedures
Ongoing.  Bad data points will be removed for Final Data submission.
RevA = Field Quality Data
RevB = Preliminary Data, processed 8/31/12 with an improved instrument 
sensitivity calibration, please check for updates
