  • ´More Stations. More Data. Better Forecasts.´ – the NYS Mesonet

    “More Stations. More Data. Better Forecasts.” – that’s the slogan of New York State Mesonet. The weather observation network consists of a total of 125 weather stations all over the state of New York and Lufft was selected as one of the vendors to support them in capturing the data. All 125 of the weathers stations have the standard instrumentation suite. Of those 125, 17 ...

  • A study of radiation shield effectiveness

    A brief comparison of temperature readings in two passively-ventilated and three fan-aspirated radiation shields under conditions of low wind and relatively high insolation is presented. From each of two periods of study, two days were chosen for conditions of high insolation and low wind to illustrate a reasonable sample of the performance of the shields. A single sample of each shield was used ...

  • Calibration of selected pyranometers and satellite derived solar radiation in Puerto Rico

    Knowledge of solar radiation at the ground surface is valuable for many disciplines. In this study, ground–based sensors at Fortuna and Mayaguez, Puerto Rico, were used to calibrate daily–integrated satellite–derived solar radiation. The calibration equations yielded R² values of 0.88 and 0.83 at Fortuna and Mayaguez, respectively. A regression equation was also derived ...

  • Bright future of solar lighting

    Hybrid solar powered lighting (HSL) isn't anything like solar light based power that changes over daylight into power. Through the utilization of optical strands, HSL catches daylight, diverting it and funneling daylight into a building. At the point when there is practically no daylight, these installations use power with the goal that consistent lighting is accomplished. Gatherer ...

  • Helplessly exposed to nature? How lightning storms can be measured

    Each day, there occur about 1,000 thunderstorms with 4-10 million lightning bolts worldwide. In average, 700 people per year are hit by such light discharges, of which 75% of the hits result in long-term damages. Between three and seven cases end fatal. The risk is particularly high in the open field and is fortunately decreasing. The reason for this is that we stay more often inside in cars and ...

  • From 370km above the earth to 11000m under the sea

    It’s a bold strapline – but what does it mean? Have we opened an atmosphere research facility in outer space? Organised an aquatic Charity Day in the Mariana Trench? Well, if you didn’t know anything about Analox you’d be forgiven for wondering. After all, three-hundred and seventy kilometres above the earth is a long way from Stokesley. And eleven thousand metres under ...

  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...
