# community and public for research, logistic, and educational activities.#
# The AMRC requests acknowledgement for use of the data in any published #
# work. See http://amrc.ssec.wisc.edu/acknowledgement.html for details on #
# how to acknowledge AMRC data, displays or information. #
# If the AMRC data are critical to the work, co-authorship may be #
# appropriate. Please contact the AMRC in such a case. #

The filenames of the data are set up as follows:
The first line has some title information.
The second line has variable name. If it has “res” or “avg” in the
variable name it is an average value. 10 second observations with an
average made at 10 minutes. The instantaneous values are from the
timestamp value. The time stamps from the Freewave stations should be
pretty good. They are updated from the base station (when we can get a
connection) if there is more than 10 second discrepancy.
The third line has the units. Units are missing for T_HMP (it should be
degC)
Timestamp - UTC
Record: record number (usually not very useful)
TavgUpper- upper air temp averaged over 10 min
T_RTD - instantaneous temp reading @ timestamp
TavgLower- lower air temp (or snow temp) averaged over 10 min
T_RTDLower- instantaneous temp reading @timestamp
presRead - add 600 to get the station pressure
T_HMP- temperature from the humidity probe
U_HMP- RH
wspd_avg - average of wind speed over the 10 minutes (10 second observations)
wspd_res - vector average wind speed (over 10 minutes)
wdir_res - vector average wind direction
wdir_std - STD of the wind direction over the 10 minutes
maxws - maximum wind speed over the 10 minutes
wdirMaxWspd - direction of the maximum wind speed
TPanelAvg - average temp of the enclosure
solarAvg - avg solar from pyranometer (Wm-2)
wspdRead - instantaneous wind speed reading
wdirRead - instantaneous wind direction reading
T_panel - instantaneous enclosure temp
RawDist - distance from the ADG
SignalQuality - QC for ADG (0: not able to read distance; 152-210: good measurement; 210-300: reduced echo signal strength; 300-600: high measurement uncertainty)
Dist - distance adjusted with air temperature
battVolt - battery voltage
Pres_us - pressure signal output from the Paroscientific if used
Temp_us- temperature signal output from Paroscientific if used
