| Description | Many of the scientific needs of the ARM Program are met through the analysis and processing of existing data products into "value-added" products or VAPs. Despite extensive instrumentation deployed at the ARM sites, there will always be quantities of interest that are either impractical or impossible to measure directly or routinely. Physical models using ARM instrument data as inputs are implemented as VAPs and can help fill some of the unmet measurement needs of the Program. Conversely, ARM produces some VAPs not in order to fill unmet measurement needs, but instead to improve the quality of existing measurements. In addition, when more than one measurement is available, ARM also produces "best estimate" VAPs. A special class of VAP called a Quality Measurement Experiment (QME) does not output geophysical parameters of scientific interest. Rather, a QME adds value to the input data streams by providing for continuous assessment of the quality of the input data based on internal consistency checks, comparisons between independent similar measurements, or comparisons between measurement with modeled results, and so forth. [taken from http://www.arm.gov/data/vaps_all.php] One of the ARM data centers, the External Data Center or XDC at Brookhaven National Laboratory, also adds value to ARM information by identifying sources and acquiring “external data” to augment the data being generated within the program. These external data sets are converted, processed, and carefully evaluated for their value to the overall ARM program. See the list of ARM’s External Data Set Descriptions at http://www.arm.gov/xds/. Data Plots are also value-added products from ARM. Users may access archived plots or use the NCVWeb to plot data as they order it or on a “standing-order” basis. NCVWeb is an interactive NetCDF data plotting tool that eliminates the need for separate visualization software. See the information page about ARM’s data plotting options at http://www.arm.gov/data/data_plots.stm. The Office of Biological and Environmental Research in DOE's Office of Science is responsible for the ARM Program. The ARM Archive physically resides at the Oak Ridge National Laboratory.
