Abstract:

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 Tropical Western Pacific (TWP) locale was the second field measurement site implemented by the U.S. Department of Energy's (DOE's) Atmospheric Radiation Measurement (ARM) Program. TWP began phased operations in 1996 at its first facility on Manus Island. The second facility on Nauru Island was implemented in 1998. In 2002, a third facility in Darwin, Australia was completed to support the first two sites. The availability of data from Darwin is subject to interruption when instruments or parts are needed to repair Manus or Nauru. Data from these sites will be used by scientists to study the effects of this region on the global climate. The TWP locale is the area roughly between 10 degrees N to 10 degrees S of the equator from Indonesia to near Christmas Island. This region of the world plays a large role in the interannual variability observed in the global climate system. For instance, the El Nino/Southern Oscillation phenomenon has far-reaching implications for weather patterns over much of the Northern Hemisphere, and perhaps the entire planet. The TWP consistently has the warmest sea surface temperatures on the planet and is referred to as the Pacific warm pool. The warm pool supplies heat and moisture to the atmosphere above it, resulting in the formation of deep convective cloud systems, which in turn produce high-altitude cirrus clouds that spread out over much of the region. These cloud systems regulate the amount of solar energy reaching the surface of the earth and the amount of the earth's heat energy that can escape to space. Improved understanding of the interaction between clouds and incoming and outgoing energy will improve the general circulation models used for climate research. For specific information on Darwin, see "http://www.arm.gov/sites/twp.stm". Surface meteorology data at Darwin is 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 Darwin site (C3). Surface Meteorology Station (SMET) For complete information on the SMET, see "http://www.arm.gov/instruments/". The SMET uses mainly conventional in situ sensors to obtain 1-minute statistics of surface wind speed, wind direction, air temperature, relative humidity, barometric pressure, and rain-rate. At Darwin (C3) SMET data is available for 2002-03-12 to present. ARM data stream is coded as follows: twpsmet60sC3: Surface Meteorology (SMET) station: 60-second meterological data Additional data streams or value added products may be added in the future.

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.

Attribute_Accuracy_Report:

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.

Access_Instructions:

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.
