Original archive format for hourly SO2 data

There are three lines of information at the top of the file.

There is one line of data for each hour:
YY = last two digits of year
MM = month
DD = day of month
HR = hour of day (end time of sample)
A, B, C, ...T, 1, 2, ...0 = Receptor ID for 30 receptors
Concentration values are in PPB

Here are the first few lines from the Developmental data set listing of SO2 values.
