1st col: year
2nd col: month
3rd col: day
4th col: daily precipitation, in inch
5th col: maximum air temperature, in ¡F
6th col: minimum air temperature, in ¡F
7th col: mean air temperature, in ¡F
8th col: SWE, in inch, reset to zero on 1 October at the start of each water year
In each text file, ÒnanÓ indicates missing or filtered out data after the BCQC procedures.
