Researchers create new software for the new European-Japanese Earth observation satellite EarthCARE

Preparations for the launch of the new Earth observation satellite EarthCARE (Earth Cloud Aerosol and Radiation Explorer) at the end of May are in full swing. The joint mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) will measure clouds, aerosol and radiation more accurately than ever before. This will be made possible by linking four state-of-the-art instruments. ....

SI-traceable mercury measurement results with the VSL primary mercury gas standard

A primary mercury gas standard was developed at VSL to establish an SI-traceable reference point for mercury concentrations at emission and background levels in the atmosphere. The primary gas standard has been developed as a mercury gas generator to establish metrological traceability of mercury concentration measurement results, based upon a gravimetric approach, for ambient air levels as well as higher concentrations.
The working principle of the primary mercury vapour generator is based on diffusion according to ISO 6145-8:2005. Specially developed stainless-steel diffusion cells are filled with approximately 2 mL of elemental mercury. The mercury vapour diffuses from the cell through a capillary. To obtain several diffusion ranges, cells with different capillary diameters are used. By weighing the diffusion cells at regular time intervals on a high-resolution analytical balance the mercury mass flow rate ....
