Summary
The Atmospheric Radiation Measurement (ARM) Program is the largest global
change research program supported by the U.S. Department of Energy (DOE). ARM
scientists focus on obtaining field measurements and developing models to
better understand the processes that control solar and thermal infrared
radiative transfer in the atmosphere ... (especially in clouds) and at the earth's
surface.
The URL for the ARM Data Archive is http://www.archive.arm.gov/. The URL for
general information about the ARM program is http://www.arm.gov/.
The data stored by the ARM Archive includes numerous parameters about radiative
flux, meteorology, water vapor and clouds.
The North Slope of Alaska/Adjacent Arctic Ocean (NSA/AAO) site is providing
data about cloud and radiative processes at high latitudes. These data are
being used to refine models and parameterizations as they relate to the Arctic.
The NSA/AAO site is centered at Barrow and extends to the south (to the
vicinity of Atqasuk), west (to the vicinity of Wainwright), and east (to
Oliktok).
Surface meteorology data at Barrow and Atqasuk are collected using many
specialized instruments. Detailed information on each instrument is available
at http://www.arm.gov/instruments/.
The following list contains the instrumentation used for surface meteorology
and the data available for the Barrow and Atqasuk sites.
Barrow Meteorology Station (BMET).
Surface meteorology at Barrow is obtained by using mainly conventional in situ
sensors on the Barrow Meteorology station (BMET). For complete information on
the BMET, see http://www.arm.gov/instruments/. The BMET
station directly measures wind speed, wind direction, air temperature, and
relative humidity at 2 m, 10 m, 20 m, and 40 m. Vector-averaged wind speeds,
vector-averaged wind directions, dew points, and vapor pressures are computed
from these primary measurements. Periodically, 2 m air and dew point
temperatures are measured using a chilled-mirror hygrometer. Barometric
pressure, visibility, and precipitation at the surface are also directly
measured.
Meterological data at Barrow are available from 1998-03-20 to present.
ARM data streams are coded as follows:
nsacmhC1: chilled mirror humidity
nsamettwrC1: surface meteorological measurements and statistics at four tower
levels
nsaorgC1: optical rain gauge measurements: precipitation rate and accumulation
nsapwsC1: present weather sensor measurements of visibility and precipitation.
Additional data streams or value added products may be added in the future.
Surface Meterological Station (SMET).
Surface meteorology at Atqasuk is obtained by using a 10-m tower and nearby
SMET. For complete information on the SMET, see
http://www.arm.gov/instruments/. The SMET stations
directly
measure: (1) wind speed at 10 m, (2) wind direction at 10 m, (3) air
temperature at 2 m, (4) relative humidity at 2 m, (5) barometric pressure at 1
m, and (6) precipitation.
Meterological data at Atqasuk are available from 2001-03-31 to present.
ARM data streams are coded as follows:
nsacmhC2: chilled mirror humidity
nsamettiptwrC2: surface meteorological data at 6-m and 2-m heights
nsapwsC2: present weather sensor measurements of visibility and precipitation
nsasnodepC2: snow depth
Additional data streams or value added products may be added in the future.

Description:
This catalog lists the data streams that are currently available from the ARM
Archive. The data streams are listed by file format type (i.e, CDF, HDF, RAW,
JPG, ASC, and Other) and then by the site where the data are collected. Each
list contains the name of the data streams in alphanumeric order, the number of
files within the data stream, the minimum data date, and the maximum data date.
The sites that have the word development in parenthesis are data processes
which are operated during the final phases of implementation of a data source,
resulting in data which are labeled as Development. Development data are
frequently available to users, but additional information about the operating
conditions and potential for errors must be considered. The files in CDF format
are also listed in preformatted lists for those browsers that have difficulty
handling large html tables. The information in this catalog is updated about
once a month.

Quality
One of the goals of the ARM Program is to provide data streams of reasonable
quality for scientific research. Traditionally, data quality issues have been
addressed within ARM at several levels, including by instrument mentors, site
scientists, value added product scientists, and Science Team members at large.
Maintaining data quality ... for a program of the size and complexity of ARM is a
significant challenge. Efforts toward this end have matured and evolved over
the life of the program. The ARM Program Data Quality (DQ) Office has the
responsibility for ensuring that quality assurance results are communicated to
(1) data users so that they may make informed decisions when using the data,
and (2) ARM's Site Operations and Engineers to facilitate improved instrument
performance and thereby minimize the amount of unacceptable data collected. For
additional information,
visit http://www.arm.gov/data/data_quality.stm.
Access Constraints
Data of common interest from external sources are shared whenever possible, but
some sources restrict secondary distribution of data. In these cases, ARM will
seek specific allowances to distribute such data to members of the ARM Science
Team, but will observe restrictions on further distribution from the Archive if
required.
Use Constraints
Use-constraints, if any, are provided in Data Quality Reports sent with the
data files when data are requested. The automatic inclusion of a data
originator as a co-author is not insisted upon in the ARM program, but the
source of any data should be clearly recognized either as a co-author or
through an appropriate acknowledgment. The ... ARM Program should be acknowledged
in publications as the programmatic origin of the field program. ARM-funded
investigators will use the following acknowledgment: "This research was
supported by the Office of Biological and Environmental Research of the U.S.
Department of Energy (under grant or contract number - if appropriate) as part
of the Atmospheric Radiation Measurement Program." The U.S. Department of
Energy's Atmospheric Radiation Measurement Program should be appropriately
acknowledged in publications resulting from collaborative efforts in which ARM
data or facilities were used. ARM-funded principal investigators will give
proper acknowledgment to cooperating or collaborating programs in those cases
where data originating therein are being used.
