28/10/2015Eastern Brazil as a whole has lost on average 28 trillion gallons of water per year over the same time period. Augusto Getirana, a hydrologist at NASA's Goddard Space Flight Center, in Greenbelt, Maryland, analyzed the amount of water stored in aquifers and rivers across Brazil from 2002 to 2015, interested in understanding the depth of the current drought. A new data visualization of 13 years of GRACE data shows the distribution of water across Brazil.

High-precision gis sf6 micro water in Tunisia. High-precision gis sf6 micro water in Tunisiasfs-sf6 is a non-dispersive infrared (NDIR) gas sensor for ambient air monitoring, using dual-wavelength technology. It is specially designed for SF6 leakage, quality and purity analysis inside gas insulated switchgear (GIS).

Kyoto-Protokoll, Rio de Janeiro: 1992. Sulfur Hexafluoride is a colorless and odorless gas. SF 6 –gas is a non-toxic, non-flammable, stable compound. Its breakdown voltage is approximately 2.5 times higher than normal air, as the electro-negative SF 6 –molecule has a strong affinity to free electrons.
