Savannah River Experiment (DSI-9790)Entry ID: gov.noaa.ncdc.C00041
Abstract: Savannah River Experiment is historical digital data set DSI-9790, archived at the National Climatic Data Center (NCDC). Major parameters which make up this file include hourly wind speed, direction and directional range at one to three levels and ambient temperature, dew point, vertical temperature gradient, precipitation and solar radiation when available. Historically, this sampling program was ... designed to take advantage of the krypton-85 plume produced by routine emissions from the operation of chemical separations facilities at the Savannah River plant (SRP) and the availability of 13 cryogenic air samplers used by ARL in a 1974 dispersion experiment (Ferber et al., 1977).a program of weekly air sampling at 13 locations surrounding the SRP began in March 1975. Pendergast et. al. (1979) reported the weekly data for the first 1 1/2 years (March 1975 through august 1976) of this sampling program. This final report includes those data along with weekly and twice-daily samples collected from September 1976 through mid-September 1977. Continuous sampling over this relatively long period provides air concentration data over a wide range of meteorological conditions as well as seasonal and annual average concentration patterns. Related files include weekly, monthly, seasonal and annual krypton-85 concentrations. Data processing: the data are collected from a cryogenic air sampling network of 13 stations surrounding the SRP operated continuously taking weekly or twice-daily (85) Kr samples from March 1975 to September 1977. These data are reported together with the monthly (85) Kr emissions at the plant and associated meteorological data. The (85) Kr sampling data have also been averaged into monthly, seasonal, and annual concentrations. These data should prove useful to air pollution modelers for model improvement and verification.
Purpose: To make a wide range of climatic data available to researchers and the public.

Quality ATTRIBUTE ACCURACY REPORT: Data quality problems, including questions concerning the actual monthly emission for the first five months (March 3, 1975 through August 4, 1975) have not been completely resolved. NCDC, therefore, has substituted the arithmetic average monthly emission (for the period august 1975 through September 1977) for the first five months. The average value is believed to be ... within + or - 20% of the actual values for March through June 1975 but the July 1975 value has a much larger uncertainty. For the purpose of calculating long-term (seasonal annual) mean concentrations, the (85) Kr release may be assumed to be continuous, and at a uniform rate, during each month. Actually chemical separations operations are done as a batch process in separate runs lasting 10 hours or longer and there are many days with no emissions. Emission rates may vary by more than a factor of three during a run. However, separations are done around the clock (no day-night bias) on most days including weekends and the fluctuations in emission rate should not seriously affect long-term concentrations (Draxler, 1980).
