STAR The STAR program summarizes National Weather Services (NWS) meteorological data, by generating joint frequencies of 6 wind speeds, 16 wind directions, and 6 stability categories for the station and time period desired. 

The protocols and software developed in this study will give the Pacific Disaster Center tools that will enable it-and other agencies such as the Hawaii State Department of Land and Natural Resources and the U.S. National Weather Service-to conduct dam breach hazard assessments more easily. Results of these assessments are expected to be of value for disaster planning, emergency response, and flood warning.

WILLARD ( ) is a severe storms forecasting expert system which can obtain all input data from National Weather Service data lines. When severe storm situations occur, forecasters become very busy and do not have time to utilize all the data which is available. The expert system can take over the routine portion of the forecasting, leaving the experts free to focus on the more difficult and critical portions of the analysis. 

A continuous, dynamic, one-dlmenslonal model called the Pesticide Root Zone Model or PRZM, has been developed recently by EPA/ORD In Athens, Georgia (110). PRZM allows for varying hydrologic and chemical properties by soil horizon. Weather data for water flow modeling Is obtained from dally precipitation records of the National Weather Service. It has been successfully validated with atrazlne field data from Watklns-vllle, Georgia and aldlcarb data from Long Island, New York for depths less than 3 meters. 

The term 10-year, 24-hour rainfall event refers to a rainfall event with a probable recurrence interval of once in 10 years as defined by the National Weather Service. 

Daily values of the 7 A.M. mixing height (MIXHT) and wind speed (WDSPD) aloft at Fort Totten, N.Y. were obtained from the National Weather Service. Weekly averages were computed for use in the statistical analysis. 

Weekly values of average temperature (AVETEMP) and of heating (HEATDD) and cooling (COOLDD) degree days were calculated from the daily values measured in Central Park (in Manhattan) obtained from the National Weather Service. 

The sampling sites were chosen in order to investigate the spatial distribution of particulate pollutants in the valley. As an additional consideration, sites were selected to coincide with the major population centers in the valley in order to determine the concentration of respirable aerosols to which valley residents are exposed on a dally basis. Seven of the sampling sites were in the Owens Valley itself, and one site was in the Mono Lake area. Site 1 was located near the Bishop Airport at the National Weather Service Meteorological station. This site is about five miles east of downtown Bishop in the center of the... 

Recommendation 3 Utilize National Weather Service Fire Weather Forecasters for all fire weather predictions and immediately share with all personnel all information about significant fire weather and fire behavior events. 

The altitude effect (Sec. 3) and the radiation amplification factor (Sec. 4) were derived from UV-ERY measurements made simultaneously at two locations in the Czech Republic. The value of RAF obtained from the present data agrees with previous studies of other authors. The value of the amplitude effect agrees with the value used by National Weather Service and EPA [10] but is lower than the values obtained by other authors [2, 9]. The statistical model relating UV-ERY irradiance with total ozone and solar zenith angle was developed (Sec. 5 Fig. 2). Although the information on the total ozone does not satisfactorily improves accuracy of the UV-ERY forecast (further variables should be incorporated into the model to improve its accuracy), the model may be used to estimate annual and daily cycles of sun-visible UV-ERY irradiance for various total ozone levels. The results obtained show variability of the model UV-ERY irradiance related to variability of total column ozone. Specifically, it is demonstrated that the UV-ERY irradiance may exceed the annual/daily normal-ozone maxima during non-negligible portion of the year/day (about 214 months/hours) if the total ozone... 

We are grateful to the California Air Resources Board for their financial support (CARB A4-075-32) and their assistance in the field during this project. We are also grateful for the cooperation of the personnel at the Bakersfield Airport, the National Weather Service office in Bakersfield, and the Buttonwillow Recreation Department.

Re Entries [66] and [67], Refs. [66] and [67]) An online brochure accessible at Ref. [66] provides more information. Reference [67] augments Ref. [66] with still more information, including references and a few alternative formulas for wind-chill temperature W. (In Australia the wind-chill temperature >V is dubbed as the apparent temperature AT.) In this Sect. 4.2. we always calculate W based on the formula employed by the U. S. A. National Weather Service [Eq. (14)].
