Data collection weather

Performance data Two moisture monitoring systems were installed, one at Disposal Area A and one at Disposal Area AB plus in May and November 1999, respectively. Each monitoring system has two stacks of time domain reflectometry probes that measure soil moisture at 24-in. intervals to a maximum depth of 78 in., and a station for collecting weather data. Based on nearly 3 years of data, there is generally <5% change in the relative volumetric... [Pg.1082]

The instrument for measurement of radon with weather parameters and water use was designed, calibrated and used in the field for 1.5 years with excellent results. The power surge and power interruptions were the only limitations on the use of the instrument. The system software was written mostly during the design phase of the project. However, modifications were made in the software to permit better data collection during power interruptions. Battery backup was needed to keep the data during interruptions of our one week studies. [Pg.46]

A relatively simple statistical downscaling technique which may be applied quickly to a large number of models is the use of correction factors based on monthly relationships between observed data collected at a particular weather station and the relevant RCM control data set for the appropriate grid-cell [40], These monthly differences (for temperature) and ratios (for precipitation) between the control and the point observations (i.e. not the gridded interpolated CRU data set) can then be used to correct the daily RCM control and scenario data. This gives bias-corrected scenarios of temperature and precipitation, which can then be used as input to hydrological models for the exploration of various management and policy formulations. [Pg.308]

Wind velocities, wind directions, wet and dry-bulb temperatures are available from data collected by the U.S. Weather Bureau or the U.S. Military Forces covering a wide range of chronological periods. Sometimes information can be obtained from weather stations located at nearby airports. [Pg.106]

Underway Analysis of the Sea Surface. All in situ measurements are made while underway to minimize the problem of comparing data collected almost instantaneously by the satellite with time-integrated data collected by the ship. In the June 1980 study, measurements were made at 9 knots, but the speed decreased as weather and high seas increased. Thermal calibrations of the satellite images were based on ship data collected nearest in time to the satellite overpass. [Pg.375]

You cannot predict the future no matter how much you know. If the dynamics are nonlinear and 1, 2, and 3 occur, then predicting the future and hence the impact of the system may be impossible beyond a certain timespan. The prediction of another chaotic event, weather, has proven recalcitrant even with the massive resources put into research and data collection. It may be that ecosystems and the ability to predict impacts may bear a similar fate. [Pg.347]

A program of onsite data collection, supplemented by National Weather Service (NOAA) summaries from locations near a specific site, will be conducted. Information from the onsite program will be used to confirm that the limiting offsite dose analyses and annual average X/Q values are adequate relative to exclusion area boundary radius and low population zone requirements. [Pg.66]

The term data intensive applications or data intensive computing [1-3] is used to name a specific class of applications. Examples are web search providers, medical imaging, astronomical data analysis, weather simulation, or analyzing data collected during physical experiments. These problems all involve processing large amounts of data. The performance of such applications is usually limited by data access times rather than by pure computational power. [Pg.29]

The key to normal operations data is to collect it in a non jeopardy, de-identified manner. Non jeopardy is not immunity I say again - non jeopardy is not immunity The data collected are all in terms of the threat and air management stractme. Threats are external to the individual. Errors are internal, made by the individual. Individuals do not see or report most of the threats that they deal with because they deal with them daily. Example weather if it is 120 degrees on the ramp or if it is minus 20 with ice and snow, the bags still need to be loaded, the engine still needs to be fixed and the crew still needs to do a walk aroimd inspection. Most do not see the weather as a threat they see it as just another lousy day. Mistakes, slips, lapses, commissions, omissions, and other unintentional errors, on the other hand most likely go unreported due to fear of punishment or simply embarrassment. [Pg.15]
