Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
Atmospheric remote sensing is vitally important to addressing major societal challenges related to climate change and atmospheric pollution. An EU-funded project is reducing the uncertainty in critical atmospheric parameters and training a new generation of scientists in new observation techniques.
