Introduction
Weather conditions at Smith College’s Ada & Archibald MacLeish Field Station are recorded at
the WhatelyMet weather station. This weather collection site is located at the end of Poplar Hill
Road in Whately, Massachusetts, USA (Latitude 42 deg. 26 min. 56 sec. N Longitude 72 deg.
40 min. 50 sec. W). The meteorological instruments of WhatelyMet (except the rain gauge) are
mounted at the top of a tower 25.3 m tall, well above the surrounding forest canopy. The tower
is located on a local ridge at an elevation 250.75 m above sea level.
This report describes the weather data collected at WhatelyMet
during 2013. It provides highlights
of the year’s weather as well as
general trends that were observed.
We hope that you find the report
both interesting and useful. All the
data reported in this document is
available electronically. Please direct
all questions and data inquiries to

2013 MacLeish Field Station Weather Report
Definitions of Climatic Indicators
The precipitation and biological temperature indicators
calculated for this report provide a method of comparing general, biologically meaningful climatic trends in
different years. The indicators are based on average daily
temperatures and rainfall summations. Even though days
are in the name of the temperature indicators, they do not
actually reflect periods of 24 hours. The indicators really
measure the number of degrees the average temperature
was above or below a threshold temperature each day of
the year. These values are described at http://ccr.aos.wisc.
edu/climate_modeling/wisconsin_Climate/descriptions.
php. All terms were defined in degrees Fahrenheit and
converted to degrees Celsius for this report.
Freezing Degree Days—The number of degrees Fahrenheit
that the daily mean temperature is below 32 °F. For example, two days with daily mean temperatures of 20 °F and 40
°F have 12 and 0 freezing degree days, respectively. Annual
total freezing degree days are calculated by summing all of
freezing degree days.
Growing Degree Days—The number of degrees Fahrenheit
that the daily mean temperature exceeds 50 °F . For example, two days with daily mean temperatures of 75 °F and 40
°F have 25 and 0 growing degree days, respectively. Annual
total growing degree days are calculated by summing all of
growing degree days.
Last Spring Freeze Date—The last day between January 1st
and mid-summer with a low temperature below 32 °F.
First Autumn Freeze Date—The last day after mid-summer with a low temperature below 32 °F.
Length of the Growing Season—The number of days between the last spring freeze and first autumn freeze.
Frequency of 1” Precipitation Events—The number of
days per year with precipitation of at least one inch (25.4
mm).
Frequency of 2” Precipitation Events—The number of
days per year with precipitation of at least two inches (50.8
mm).
Paul Wetzel, manager of weather data
collection, climbs the WhatelyMet tower.
Frequency of 3” Precipitation Events—The number of
days per year with precipitation of at least three inches
(76.2 mm).

APPENDIX B
List of Sensors & Measurement Ranges
Relative humidity and temperature are
measured with a R.M. Young Co., Model
41382, relative humidity and temperature
probe. The probe is housed in a radiation
shield and ambient air is continuously
blown past the sensor to reduce temperature fluctuation from solar radiation. The
calibrated measuring range of the temperature probe is -50 to +50˚C, with an accuracy of ±0.3˚C. The relative humidity probe
has an accuracy of ±2%.
A pyranometer (Kipp & Zonen, model
CM 3) measures solar radiation received in
the horizontal (180 degrees) field of view.
Typical accuracy is ±5%.
Barometric pressure is measured with an
R.M. Young barometric pressure sensor,
model 61202V. The operating temperature
is –50 to +60 ˚C, with an accuracy of ±0.3
hPa at 20 ˚C.
2013 Annual Weather Report
Appendix B

Wind velocity and direction are measured with a 2-axis,
non-moving parts, ultrasonic anemometer (R.M. Young,
model 85004). Wind measurements are based on the transit
time of ultrasonic pulses between four transducers. The
transit time between the transducers is altered as the wind
blows to calculate wind velocity. Wind direction is determined from relative velocities along each acoustic path.
The unit is heated to prevent ice and snow buildup. The
anemometer has a wind speed range of 0–70 m/s, with accuracy in the 0–30 m/s range of ±2% or 0.1 m/s. The wind
direction accuracy is ±2%.
Precipitation is measured using
a Campbell Scientific 8” heated
siphoning tipping-bucket rain gauge
located on the ground. The bucket
tips when 0.01 inches (0.254 mm)
of precipitation accumulates. The
rain gauge has a precision of +/– 2%
for rainfall intensities up to 19.7
in/hour (500 mm/hr). Note that if
there is a large amount of snowfall
it will take 1-3 days for all of the
snow to melt and be recorded by
the gauge. This is especially true if
large snowfalls occur during or are
followed by very cold temperatures.
The result is that large snowfall
events look like extended precipitation events.
Also note that the rain gauge is
located within 2 m of a one story
building. The building may obstruct
accurate measurements of certain
rain events.
