NOTE:  AgriMet weather data is reported in local time (Mountain and Pacific
       time zones).  The reported time also reflects daylight savings time 
       (DST) when in effect.  All values above are instantaneous at the time 
       of observation, except as noted.  All temperature values are Fahrenheit, 
	   except COVM soil temperatures (Centigrade).

   ************  DAYFILE FLAGS **********

AgriMet dayfile weather data may have quality control flags immediately
following the data values.  Following is an explanation of these flags:

e	Estimated or Edited Data

        Hard Flags (Probably Bad Data)
        ------------------------------
n	No Value
m	Missing Characters in Data Transmission
p	Parity Error in Data Transmission
i	Illegal Character in Data Transmission
f	Undefined Format
?	Math Error (Divide by Zero)

        Soft Flags (User Beware)
        ------------------------
-	Low Limit Exceedance Flag
+	High Limit Exceedence Flag
^	Rate of Change Exceedance Flag
~	No Change Limit Flag
