Enclosed is a headed data file of the Nitrogen data for summer Blodgett 1998

	I have removed the generator spikes manually from each compound so that this data
is minimally impacted. Note that a few residue spikes remain. These can be easily
identified by the sudden rise of one data point above the signal level with the quick return
to the previous level.

	The raw data was collected at 10 second intervals and was AVERAGED to 1
minute intervals. The time base of the NO/NOy data was adjusted to the NO2 data time
base via comparison on spikes. Finally, these 1 minutes data points were AVERAGED onto
the 1/2 hour time grid as presented here.

	Note that the background zeros of the NO and NOy measurements are not corrected and are known to drift slightly (approximately 50 ppt) with time (over a day or two) and so the NO measurements in particular should be used with caution (NOy measurements should be relatively unaffected).
