Wind data have been measured by an anemometer mounted 3 m
above the ground at Hubbard Brook Experimental Forest Headquarters
since 1965. Prior to 1981, every mile of wind movement caused a tick
mark on a strip-chart recorder, and wind direction as N, S, E, W, or
a combination, was recorded continuously. Since 1981, wind speed and
direction have been collected by an automatic data logger system. In
2004, a R.M. Young company wind speed direction sensor (model 05103)
was installed. Since that time wind direction (azimuth) are based on
a 0 to 360 degree scale.

DATA DESCRIPTION
Wind data have been measured by an
anemometer mounted 3 m above the ground at HBEF
Headquarters during various time periods since
1965. The anemometer and wind vane system was
run at Headquarters from October 27, 1965
through July 22, 1981. Before 1981, every mile
of wind movement caused a tick mark on a
strip-chart recorder, and wind direction as N,
S, E, W, or a combination, was recorded
continuously. Since 1981, wind speed and
direction have been collected by the automatic
data logger system at Headquarters. In 2004, a
R.M. Young company wind speed direction sensor
(model 05103) was installed. Since that time
wind direction (azimuth) are based on a 0 to 360
degree scale.
SAMPLING DESIGN
From October 26, 1965 through July
22, 1981, an anemometer and wind vane system was
run at HBEF Headquarters. Data were recorded on
a strip chart recorder, with a mark for each
mile of movement, and direction given by the ON
position of four pens, for S, W, N, and E. The
charts have been read only for the periods
October 1965 to August 1967, and April 1971 to
June 1973, and are therefore the only data
currently available prior to 1981. Missing data
occurs for various reasons: out of ink, bad
sensor switches, power supply problems, etc.
Gaps vary from a few hours to many months.
Beginning in 1981, wind speed and direction were
included in the automatic data logger system at
Headquarters. An additional, totalizing,
anemometer is read every working day at 8:00
a.m. For many years these data were noted on the
wind speed and direction strip chart, so access
requires unrolling those charts. Since 1981 the
data are on paper and have not been digitized,
except for the purpose of filling missing
values. Undocumented wind charts are in the
process of being read and added to the data
base. Missing data after 1981 is due to
datalogger malfunctions.

NOTES
The primary cause of lost data has been
lightning damage to the anemometer reed switch. On
some dates, the wind speed was measured but the
direction was not due to malfuntioning equipment.
Ideally, the sum of wind direction values should be
equal to the total wind speed. Total wind speed
values flagged with the letter "e" are estimated
using data from the totalizing anemometer. Over
weekends, estimated daily values are the same for 3
consecutive days.
The data is physically located at the
USDA Forest Service, Durham, NH and was last updated
in 2013.
