DATA DESCRIPTION
------------------------------------------------------------------------

NOTES: 
	- .dat files are the output from our Campbell Scientific loggers but are regular .csv files. To read like a .csv, just change the file extension.
	- We are aware with an issue affecting the air temperature readings in the S2S1_Met_data.dat file. We beleive this is related to the logger program and might be due to a sampling frequency issue 
	  where the sampling of another instrument occurs at the same time and it produces erroneous values. Diagnosing/fixing the problem will require bringing the system offline, so it's likely that 
	  we'll address it summer 2026 during our normal maintenance period. Temperatures from flux files or the Snow Lab SNOTEL data can be used instead.
