Sponsored content: Why are airflow rotameters so popular?
A rotameter is a flow meter instrument that measures the volumetric flow rate of a gas or fluid. It consists of a tapered tube with a moving internal float. These are sometimes known as mechanical flow meters, gravity flowmeters or variable area flowmeters.

Describing pollutant distribution in 3d
A team led by environmental physicist Stefan Schreier at the University of Natural Resources and Applied Life Sciences in Vienna is attempting to build up a better picture of nitrogen dioxide pollution in the city. The work includes the first attempts to describe how this pollution is distributed in the vertical axis, from street-level upwards, as well as the use of data from satellite measurements.
