Key to AgriMet Hourly/15 Minute Weather Parameter Codes and Flags
CODE ITEM STANDARD FREQUENCY
OB = TEMPERATURE, (Instantaneous Deg F) 15 min
TU = RELATIVE HUMIDITY (Instantaneous Percent) 15 min
TP = DEW POINT TEMPERATURE (Instantaneous Deg F) 15 min
WD = WIND DIRECTION (Mean of Vectors, Deg Azimuth) 15 min
WG = PEAK 15 MINUTE WIND GUST (Last 15 min, mph) 15 min
WS = AVG WIND SPEED (Last 15 min, mph) 15 min
PC = ACCUM PRECIPITATION (Cumulative Inches) 1 hour
SQ = ACCUM SOLAR RADIATION (Cumulative Langleys) 1 hour
UI = ACCUM WIND RUN (Cumulative Miles) 1 hour
SI = HOURLY SOLAR RADIATION (Langleys) 1 hour
(added to all stations in July, 2007)
NOTE: All AgriMet stations report the above DAYFILES parameters.
Selected stations are also set up with additional special parameters.

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
