water, air, wind, clouds, atmosphere, weather, cold, earth, pressure, meteorology. Barometric Pressure: The pressure exerted by the atmosphere at a given point on the Earth; Ceiling: The lowest cloud layer that is overcast or broken cloud; Celsius: A temperature scale where water at sea level has a freezing point of 0 degrees Celsius and a boiling point of +100 degrees Celsius; Cirrus Clouds: High-level clouds (5,000 meters or more), composed of ice crystals and appearing in the form of white, delicate filaments or white or mostly white patches or narrow bands; Climate: Average weather conditions in an area over a long period of time; Climatologist: A scientist who studies the climates of the Earth; Cold Front: The leading edge of a cooler air mass; Convection: The vertical transport of heat and moisture, especially by updrafts and downdrafts in an unstable atmosphere such as a thunderstorm; Cumulus Clouds: Detached clouds, generally dense and with sharp outlines, showing vertical development in the form of domes, mounds, or towers; Cyclone: In the Northern Hemisphere, a closed counter-clockwise movement of air-known as a circulation - around a low pressure center; usually called a low The term is frequently misused to describe a tornado; Dew Point: As the surface of the earth cools at night, warm moist air near the ground is chilled and water vapor in the air condenses into droplets on the grass and other objects. WeatherInstruments wind, straw, holes, wind streamer, thermometer, plastic wrap, rain, instructions, ruler, barometer. 2. PLACE the straw horizontally on the plastic wrap so that two-thirds of the straw is on the can. 2. TIE the other end of each of the fishing lines to the tree branch so the objects are hanging freely, approximately1.25 cm (1/2 inch) apart from each other. Rain clouds are made of droplets of water so small there are billions of them in a single cloud. 3. STAND the ruler inside the glass container so that the ruler rests on the bottom of the container. 5. CUT a piece of white yarn and a piece of red yarn, both two inches longer than the distance between the two holes. MR1209.appd http://www.rand.org/publications/MR/MR1209/MR1209.appd.pdf defenses, weapons, reentry vehicle, missile defenses, terminal-area, targets, ballistic coefficient, nuclear, deterrent, countermeasures. Chapter Five asserted that unsophisticated countermeasures could readily saturate terminal and midcourse missile defenses based in the continental United States. This appendix contains a thought-experiment to illustrate the possibility of an unconventional, unsophisticated countermeasure against terminal-area ballistic-missile defenses. One way to saturate defenses during the midcourse portion of a missile's trajectory outside the atmosphere is to deploy relatively inexpensive, unsophisticated decoys (such as balloons or fragments of the booster) in large numbers and to alter the appearance of real targets to help confuse sensors trying to sort the real and false targets, for example, by deploying the real targets in what amounts to another decoy (APS, 1987; Lewis and Postol, 1997). Other possible weapons of terror or deterrence (depending on perspective and purpose) include chemical and biological weapons, and these may be more readily available to what might be called rogue states. zx_ds survey, Ashtech, operating, receiver, GPS, temperature, kit, Instant-RTK, RTK, card. A rugged, weather-proof dual-frequency GPS receiver designed to provide surveyors with cost-effective, centimeter-accurate positions in a variety of system configurations. A removable battery and flash memory card provides enough capacity to last all day for maximum utility. Use the easy-to-operate interface on the front panel for important functions such as site information entry, checking survey status, and set-up of RTK base stations without the additional cost of a handheld controller. Add an optional kinematic kit to make topographic feature collection more cost effective. Instant-RTK gives you the ability to initialize the centimeter solution in a fraction of the time of conventional RTK systems. kelly http://www.eumetsat.de/en/area2/proceedings/eump29/pdf/session_6/verbal/kelly.pdf assimilation system, winds, Meteosat Winds, quality indicator, radiance data, motion winds, MPEF, ECMWF, sampling, AMW. Enhanced Meteosat wind data sets are provided every 90 minutes together with the Quality Indicator (QI) derived during the quality control of the Meteorological Product Extraction Facility (MPEF) at EUMETSAT. All three channel Cloud Motion Winds (CMW) and clear sky Water Vapour Motion Winds (WVMW) have been passively monitored by comparison to the ECMWF background field. The evaluation of the relationship between the MPEF QI and the background departures indicate possible benefits to be gained from the use of the QI within the observation screening of the assimilation system. The MPEF quality indicator is used as a selection criterion and the overall effect is an increase of active Meteosat winds by a factor of 2. aneroid http://www.bom.gov.au/info/leaflets/aneroid.pdf barometer, pressure, reading, hectopascals, air, weather, pointer, sea level, instrument, aneroid barometer. A barometer is an instrument for measuring the pressure of the air, due to the weight of the column of air above it. If we use rough figures, we can say that the reading decreases by three hectopascals for each twenty-five metres of ascent. For example, if the barometer reads 1020 hectopascals at the sea coast and you drive along a mountain road 325 metres high, the pointer should move down the scale to about 980 hectopascals. High and low pressure systems in the atmosphere move around the earth's surface, and the movements shown on the face of a barometer attached to the wall of your home indicate the changes of pressure as they occur directly above you. assessment2Student water, temperature, Station, sheet, picture, white jar, mass, instrument, magnet, water cycle.

Please be assured that Daves Creek has an adequate supply of science books and science kits for teaching this interactive, handson science program. There will be some Daves Creek students affected, so we will be part of the process for reviewing and making suggestions to the Board of Education regarding those changes. Parent representatives will be hearing the initial plan and hosting a meeting at the school for parent information and comments. The office staff cannot verify changes and inform teachers if they receive them over the telephone or late in the day. Please make sure your child has a good night's sleep and eats a good breakfast each day of testing. CSO_Dec02 CSO, Reserved Channel, control, sewer, MWRA, discharges, water, Dorchester Bay, CSO reassessment, separation. The CSO reassessment involves many stakeholders with expectations that must be considered in determining which alternatives are advanced. Existing water-quality standards call for CSOs to beaches---designated "fishable/swimmable"---to be eliminated unless MWRA can demonstrate that is not feasible or affordable. Authority (MWRA) is developing ways to control Combined Sewer Overflows (CSOs) as part of the longterm CSO control plan in compliance with the Federal Court Order guiding the clean up of Boston Harbor. As part of its ongoing South Boston CSO reassessment, the Massachusetts Water Resources Authority (MWRA) has identified four main options to control combined sewer overflows (CSO) to the beaches and Reserved Channel. w_stn_ds2 sensors, logger, power, Delta-T, mast, probe, solar, measuring, M2-Enclosure, DL2e.

People see satellite weather images every day. With coffee in one hand and a TV remote control in the other, they watch ominous storm fronts marching across the continent as they hurry through their morning rituals. Or, they take a more leisurely approach and surf the Web to find the weather images of their choice. Hams are not content to merely communicate through the instruments of multinational corporations, we want to generate and receive signals our-selves---with equipment we control and operate. That's why weather satellite image reception remains a vibrant subset of the Amateur Radio hobby. The Hamtronics R139 weather satellite receiver is essentially a five-channel crys-tal-controlled scanner that sweeps through the APT satellite frequencies mentioned above. andersen2 http://www.eumetsat.de/en/area4/saf/internet/other_reports/andersen2.pdf channel, Levitus, temperature, matchup, NOAA, database, AVHRR, extraction, sea, climatology. A matchup database co-locating NOAA AVHRR data and in-situ ship and buoy measurements of surface temperature and other parameters has been developed as a supplement to the CMS and pathfinder databases. The taped archive of AVHRR data covering the period between November 1993 and February 1996 was applied in the extraction of the present matchup database and daily extraction and archiving was reinstated in October 1997 to ensure and monitor the quality of the Ocean and Sea Ice SAF as well as DMI North Atlantic and Baltic sea surface temperature products. Finally climatological surface temperature data from Levitus World Ocean Atlas (Levitus et al., 1994), and Reynolds and Smith (Reynolds and Smith, 1994) are merged into the record, here missing temperatures (Levitus) are assigned a value of -100.0. colorado http://www.lpi.usra.edu/publications/reports/CB-1152/colorado.pdf temperature, transmission, power, mars, batteries, octets, heat, satellite, instruments, measurements. Our module is capable of measuring temperature, pressure, wind speed, and particle concentration. Our design is an expanding modular structure, similar to a Hoberman Micro Sphere® by Hoberman Designs, Inc, in which the instruments are protected from the harsh atmospheric conditions yet are still able to take measurements. This is a Thin Film Platinum Resistance Temperature Detector (RTD). With an operating current of 1 mA (2 mA maximum), this thermometer will require very little power to operate [20]. Extending vertically from the reflector is a pole that rises to 4.46 cm away from the reflector in order to have maximum transmission pattern. mcb-30 channel, mobile, microphone, MCB-30, antenna, output power, FCC Rules, transmit, mile communication range, radios. Maxon mobile CB's provide reliable two-way communication between vehicles. The radios are available in two versions: the MCB-30 is ideal for traveling and the MCB-30MO in Mossy Oak® New Break-Up® camouflage housing for off-road adventurers. Range will vary depending on the type of antenna used and geography of surrounding environment. Mossy Oak and New Break-Up are registered tradenames of Haas Outdoors, Inc.

Cruise_Report transmitter, electrode, instrument, recorders, CSEM, cruise, Thompson, magnetometers, seafloor, tow. By using a combination of controlled source EM (CSEM) sounding, in which a deeptowed EM transmitter broadcasts energy to seafloor electric field recorders, and magnetotelluric (MT) sounding, a method utilizing time variations in Earth's natural magnetic field, electrical conductivity structure can be studied from depths of a few hundred meters down to the lower mantle. All seafloor instruments recovered good quality data, with the exception of one instrument that failed to leave the seafloor; the instrument is communicating via acoustics and we will make further attempts at recovery in August. The only other down time associated with the transmitter was associated with a broken cable on the near electrode.
