  • Support to Aviation Control Service (SACS): an online service for near-real-time satellite monitoring of volcanic plumes

    Volcanic eruptions emit plumes of ash and gases into the atmosphere, potentially at very high altitudes. Ash-rich plumes are hazardous for airplanes as ash is very abrasive and easily melts inside their engines. With more than 50 active volcanoes per year and the ever-increasing number of commercial flights, the safety of airplanes is a real concern. Satellite measurements are ideal for ...

  • Testing for nonlinearity in European climatic time series by the method of surrogate data

    Using temperature and pressure records from Czech meteorological stations and NCEP=NCAR reanalysis series, we tested for the presence of detectable nonlinearity in univariate and multivariate climatic time series. The method of surrogate data was utilized for nonlinearity detection – results of nonlinear prediction for the original series were compared to the results for series whose nonlinear ...

  • Time to stop losing ocean data to vandalism

    More must be done to prevent damage of ocean data buoys that costs money, vital data — and lives, say Sidney Thurston and M. Ravichandran. The global community relies on a rapidly expanding ocean observing network to understand the climate and ecosystems, to help warn against ocean-borne hazards such as tsunamis and storm surges caused by cyclones, and to support sea rescue ...

  • The "MAESTRO system 1.0": a new modelling system for impact studies over complex terrain

    To perform realistic impact studies over complex terrain, ATM-PRO s.p.r.l. developed a new 3-D dispersion model, MAESTRO system 1.0*. This system effectively couples a 3-D meso-meteorological model to a Lagrangian dispersion model and runs on a PC at reasonable CPU costs. It takes into account topography and land use. It simulates dry and wet deposition, gravitational settling and plume rise. ...

  • Relief for Allergy Sufferers: AQM Stations from Plair Visualize Pollen

    The prevalence of pollen allergy is vast, attaining 25-30% of the population worldwide, and this number continues to grow. Symptoms include rhino-conjunctivitis, asthma and eczema. Plair’s Rapid-E system powered with artificial intelligence provides real-time pollen measurements together with other particle present in the air to ...

  • Summertime runoff variations and their connections with Asian summer monsoons in the Yangtze River basin

    Research on the summertime runoff variations and their connections with Asian summer monsoons can give insights for explanation of the hydrological processes and climate change in the Yangtze River basin. Currently, regional studies are focused on the relationships between Asian summer monsoons and meteorological elements. However, research on the runoff variations and their connections to ...

  • Using the HydraProbe Soil Sensor for Determination of Flood Risk in the New York State Mesonet

    New York's Mesonet uses the HydraProbe and other meteorological sensors to help forecast flood hazards and climate. In January 2014, the Department of Homeland Security established the New York State Early Warning Weather Detection System. The centerpiece of the system is the New York State Mesonet, a network of 125 weather stations across the state, with at ...

  • Case study - SEAWATCH Peru

    The El Niño phenomenon, of which much has been spoken over the last few years will now be monitored by "El Instituto del Mar del Perú" (IMARPE) and the Hydrographic Service of the Peruvian Navy with the help of Fugro OCEANOR's technology. Over the last few years, many articles have been written by the media concerning EL Niño. El Niño marks the arrival of warmer water ...

  • Comparative investigation of Source Term Estimation algorithms using FUSION field trial 2007 data: linear regression analysis

    Given a warning based on detections at a few sensors, it should be useful to rapidly provide an estimate of the location, time of release and amount of material released. Such information could lead to refined predictions of the hazardous area and support follow–on actions to investigate the cause and nature of the hazardous release. In September 2007, a short–range test designed to ...

  • Online Odors Monitoring in Waste Water Treatment Plants

    Odors are very distinct air contaminants as they generate nuisances (see note at the end). The factors playing a role in the determination of odor annoyance are : odor concentration and intensity, frequency, appreciation, duration, synergy and location. Chromatotec proposes an automated solution to well identify the origin and the level of odors. Technology Description We offer a ...

  • Influence of sea-land breezes on the tempospatial distribution of atmospheric aerosols over coastal region

    The influence of sea-land breezes (SLBs) on the spatial distribution and temporal variation of particulate matter (PM) in the atmosphere was investigated over coastal Taiwan. PM was simultaneously sampled at inland and offshore locations during three intensive sampling periods. The intensive PM sampling protocol was continuously conducted over a 48-hr period. During this time, PM2.5 and ...

  • FTIR gas analyzers support management of fire at UK waste facility
