  • How Your Road Weather Stations Remain Precise into Old Age

    When the temperature is below zero and the fog settles on fields and trees like a veil, the world becomes white as in a fairy tale. But what seems so idyllic white entails risks, because the road is now covered by a fine white ice layer. No one can see with the naked eye how thick or slippery this ice layer is exactly. This can only be measured by technical assistants such as automatic ice ...

  • Modeling Tip: How to Import BREEZE AERMOD files into BREEZE Risk Analyst for Human Health Risk Assessments

    Humans can be exposed to hazardous air pollutants (HAPs) either directly through inhalation or indirectly through ingestion or dermal contact, which can result in acute or chronic health effects. The risk of exposure varies depending on a number of variables, including the meteorological conditions, local geographical and emissions characteristics, the age of the individuals being exposed, and ...

  • Open data aims to boost food security prospects

    Rothamsted Research, a leading agricultural research institution, is attempting to make data from long-term experiments available to all. In partnership with a data consultancy, is it developing a method to make complex results accessible and useable. The institution is a member of the Godan Initiative that aims to make data available to the scientific community. In ...

  • Modeling Tip: Importing & Exporting Traffic Data in CALRoads View

    The CALINE series of models was developed to estimate pollutant concentrations from motor vehicles at roadway intersections. It includes three primary models: CALINE, CAL3QHC, and CAL3QHCR. The latter allows processing of real meteorological data (up to one year) and input of vehicular emissions, traffic volume, and signalization (ETS) data. Data reflecting traffic conditions for individual hours ...

  • Satellite analysis to identify changes and drivers of CyanoHABs dynamics in Lake Taihu

    A long-term satellite-based analysis was performed to assess the impact of environmental factors on cyanobacterial harmful blooms (CyanoHABs) dynamics in a typical shallow lake, Lake Taihu. A sub-pixel approach (algae pixel-growing algorithm) was used with 13 years of MOderate-resolution Imaging Spectroradiometer (MODIS) data to evaluate changes in bloom extension, initiation date, duration, ...

  • Weathering the Storm

    Construction excavation and earthmoving recently got a bit more complicated as Phase II of EPAs Storm Water Final Rule went into effect this past spring. The change creates potential for rental dealers who specialize in construction equipment to capitalize on a unique opportunity. While the subject seems new to some, Phase II originated from a 1992 court decision handed down in a lawsuit against ...

  • Cloud simulation instead of data cloud: the CHM Simulator

    MARWIS as all-rounder: the new CHM Simulator is able to simulate clouds with the help of the sensor which is normally used for traffic meteorology applications. The name of the simulator equipment refers to the cloud height sensor CHM 15k, ...

  • Drought planning and management: experience in the Seyhan River Basin, Turkey

    The focus of this study was to integrate drought planning and management into local and regional decision-making processes in the Seyhan River Basin, which is the second-largest basin after the Nile in the Eastern Mediterranean and agriculturally one of the most productive regions in Turkey and Europe. The methodological approach consisted of two steps: Step 1 – review and analyse historical ...

  • The SESAMO early warning system for rainfall-triggered landslides

    The development of Web-based information systems coupled with advanced monitoring systems could prove to be extremely useful in landslide risk management and mitigation. A new frontier in the field of rainfall-triggered landslides (RTLs) lies in the real-time modelling of the relationship between rainfall and slope stability; this requires an intensive monitoring of some key parameters that ...

  • Variability of GPS water vapor associated with warming activity in Peninsular Malaysia during the period of 2008–2011

    This study utilizes the precipitable water vapor (PWV) parameter retrieved from ground-based global positioning system (GPS) to detect warming activity in Peninsular Malaysia from 2008 to 2011. Daily average of GPS PWV and surface meteorology data taken from six selected stations over Peninsular Malaysia are analyzed. Prior to warming detection, GPS PWV results are compared with PWV obtained ...

  • The impact of meteorology on the occurrence of waterborne outbreaks of vero cytotoxin-producing Escherichia coli (VTEC): a logistic regression approach

    This study analyses the relationship between meteorological phenomena and outbreaks of waterborne-transmitted vero cytotoxin-producing Escherichia coli (VTEC) in the Republic of Ireland over an 8-year period (2005–2012). Data pertaining to the notification of waterborne VTEC outbreaks were extracted from the Computerised Infectious Disease Reporting system, which is administered through the ...

  • Assessing droughts using meteorological drought indices in Victoria, Australia

    Droughts adversely impact rural and urban communities, industry, primary production and, thus, a country's economy. Drought monitoring is directed to detecting the onset, persistence and severity of the drought. In this study, meteorological drought indices such as the Standardized Precipitation Index (SPI), the Reconnaissance Drought Index (RDI) and deciles were assessed to investigate ...

  • Precipitation trends in Victoria, Australia

    Annual rainfall series trends were investigated for more than 100 years of data using two non-parametric trend tests Mann–Kendall (MK) and Sen's slope (Q) for five selected meteorological stations in Victoria, Australia. The annual rainfall time series showed no significant trends for any of the five stations. To assess the sensitivity of trends to the length of the time ...
