  • Safety vs. Environment Protection: Study Discovers Increasing Salt Levels in Lakes

    A recent study published by the US-American National Academy of Sciences revealed an increasing salt amount in form of chloride in rural and urban freshwater lakes around the American continent. The scientists believe, that mainly road salt distributed on icy roadways is to blame. Increasing salt levels threaten eco systems Road de-icing salt is blamed for rising salt levels in ...

  • Modeling for NAAQS Part 1: How to select the appropriate output for NO2

    The U.S. National Ambient Air Quality Standards (NAAQS) for 1-hour SO2, 1-hour NO2, and 24-hour PM2.5 use a very particular format. It is very important for all modelers (both within and outside of the U.S.) to understand how AERMOD handles this. In particular, U.S. users need to be familiar with the ...

  • Wacky Weather: What it Means for Seasonal Birds

    Last Tuesday started off like an average early-May day in the town of Carlsbad, New Mexico, with temperatures steadily rising into the low 80s. As late afternoon approached, light rain started and became stronger as the evening went on. It wasn’t until after dinner that Carlsbad resident Skye Pope noticed a much louder tapping sound on his windows and roof than simply rain, and went outside ...

  • Daily runoff prediction using the linear and non-linear models

    Runoff prediction, as a nonlinear and complex process, is essential for designing canals, water management and planning, flood control and predicting soil erosion. There are a number of techniques for runoff prediction based on the hydro-meteorological and geomorphological variables. In recent years, several soft computing techniques have been developed to predict runoff. There are some ...

  • Do you know our new sensor for traffic management applications yet?

    After a year of development work, the new Lufft stationary road weather sensor StaRWIS (Stationary Road Weather Information Sensor) is now market-ready. It can be mounted at measuring distances of 5 to 6 meters above the road and is based on the award-winning LED technology we already used for the mobile road weather sensor ...

  • The new ViewMondo variety – also suitable for airports

    With the browser-based monitoring software ViewMondo, we offer an elegant management solution for mobile and stationary weather stations since mid-2015. Once implemented, all measuring stations can be found on a map and can be evaluated in real-time. However, over the time since the introduction of the smart software, it has gained new functions than mentioned in August 2015 – ViewMondo has ...

  • Case study - Weather data for nautical information system

    In Lemwerder, Germany at the Weser River, wind direction and speed are measured and transferred in 60 second intervals via the OTT netDL 1000.  The data is transmitted, wireless, over a distance of 600 meters to the radar tower in Ritzenbuettel, where it is integrated into the ship traffic network - the Authority for Water and Navigation (WSA), Bremen. The WSA is also responsible for ...

  • First Day of Winter – Cold Weather Work Safety Information

    Today marks the first day of winter! Do you frequently work in cold weather environments? Working in cold weather can expose workers to environmental cold injuries. Hundreds of workers report cases involving days away from work caused by exposure to environmental cold each year. Environmental cold can affect any worker, especially those who work outdoors and are ...

  • 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 ...

  • ´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 ...

  • 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 ...

  • Technology Can Help Fleets Manage Potential Weather Disruptions

    Hurricane Matthew is serving as another lesson for the U.S. trucking industry on the important role technology can and should play in operating in and around storm-affected regions. More than a million residences and businesses lost power in Florida alone, and at least 38 people died as a result of Matthew’s winds and torrential rains, 19 of them in North Carolina where widespread ...
