A cloud sensor measuring more than just clouds: The CHM 15k
Atmospheric and non-atmospheric parameters in the air space challenge researchers, weather services and airports. Although these applications pursue different targets, there’s one sensor system, satisfying all of those users: the CHM 15k. It scans the atmosphere in heights of up to 15 km and detects clouds, molecules, boundary layers, droplets, visibilities and aerosols through ...

Soil climate monitoring in Antarctica
Antarctica, the coldest place on earth, has an area of about 14 million sq. km. About 98% of the continent is covered by ice, which averages about 2100 m thick. This vast ice sheet contains the earth’s largest fresh water reserve. Of the ice-free ground, only 0.3% is available for soils to form. Currently there are seven soil climate stations in Antarctica, which monitor a range of ambient ...

Continuous Ground Gas Monitoring Technical Article
It is almost inevitable in the initial phases of a construction sites development, that a Ground Gas risk assessment process is required by the local planning authority, and subsequently undertaken by a developer or their contractor. This normally encompasses spot monitoring visits that can last up to 12 months or more, if methane is found at over 5% by volume. However, it is important to ...

TOXFLAM online
TOXFLAM is a software code based on an analytical solution to the atmospheric dispersion equation for inert substances that may undergo a first-order chemical or physical decay and have a density that is similar to the air density (Bianconi and Tamponi, 1993). This general analytical solution to the dispersion equation describes releases of any duration in a finite mixing layer. The ...
