The Cary Institute of Ecosystem Studies Environmental Monitoring
Program is a long-term data collection program designed to understand
how the environment changes over time. The program includes monitoring
of climate including temperature and precipitation, as well as
variables related to air pollution, such as acid deposition and ozone,
and water pollution and other streamwater chemistry. Our solar
radiation monitoring includes diffuse and global photosynthetically
active radiation (PAR), diffuse and global shortwave radiation, net
radiation and UV. Long-term monitoring of solar radiation provides us
with an understanding of atmospheric energy dynamics, which can affect
natural and human systems. The Cary Institute of Ecosystem Studies,
Environmental Monitoring Program furnishes data under the following
conditions: The data have received quality assurance scrutiny by our
program, and, although we are confident of the accuracy of these data,
the Cary Institute will not be held liable for errors in these data.
Data are subject to change resulting from updates in data screening or
models used. Data citation: The following is a standard citation for

CR3000 Dec. 2011-present). All sensors are sampled every 2 seconds and
all data are summarized every 3, minutes, 15 minutes, hourly and at
the end of every 24-hour period. Hourly summary data units are Eastern
Standard Time (EST), where 100 is midnight to 1 a.m. EST and 2400 is
11 p.m. to midnight EST. Three minute summary meteorological and solar
radiation data have been collected since 2011 and 15-minute data since
xxxx. Snow data are collected to the nearest 0.5 inch using a ruler
and a snow depth gauge or ground measurements made within 12 hours of
the completion of a snow event. The meteorological and solar radiation
instruments are located in a flat, open field at an elevation of 128
m. GPS coordinates for the site are: N41.785823 W073.741447.
The instruments, their accuracy and our recommendation for the number
of significant figures to use:
Please note that significant figures may be reported beyond the
accuracy of the instruments. Data are reported in this manner to
maintain the capability of backing out calculations from the raw
measurements. Instrument notes including calibration, malfunctions,
repairs and anecdotal information is available upon request. The

METEOROLOGICAL DATA QUALITY ASSURANCE AND QUALITY CONTROL PARAMETERS
AND METHODS
The quality of meteorological data collected as part of the Cary
Institute Environmental Monitoring Program is assured and controlled
at several levels. Instruments are returned to manufacturers for
audits and calibration as recommended by the manufacturer or as
needed. If an instrument is known to have malfunctioned or if it is
not in place for any reason, data are either removed from the database
and replaced with missing values, or are replaced with data from a
known working instrument. The New York State Department of
Environmental Conservation has an air monitoring site co-located at
the Cary Institute. Temperature data from the DEC program were
sometimes used when Cary Institute instruments malfunctioned or were
unavailable.
Data are checked for accuracy at several levels. Meteorological data
are collected using a Campbell Scientific datalogger. The datalogger
assigns out-of-range data a value of either 6999, 9999 or -9999. Data
are downloaded from the datalogger on a daily basis and imported into
a SAS database. The SAS program used to import data contains
range-checking steps. These steps produce a temporary dataset that put
out-of-range data and data that are beyond a reasonable range equal to
missing values. These data are then checked and missing values are
reviewed. At the end of each year, a line graph of raw data is
produced together with data from previous years to check for data
points that may be outliers. All outliers are checked and, if for any
reason the value is suspected to be unreal, the value is replaced with
a missing value code.
Instrument notes including calibration schedule, malfunctions and
repairs, new instrumentation, anecdotal information etc. can be made
available on request.
