Air Quality Forecast
The NCAS Air Quality Forecast (AQF) system is a research tool used by the scientific community interested in the prediction of air quality related pollutant species over the UK. It provides a three day forecast of Ozone (O3), Oxides of Nitrogen (NOx) and Particulate Matter (PM2.5)
The NCAS AQF system, is operated by the Centre of Atmospheric and Instrumentation Research, University of Hertfordshire and the forecasts are publicly available. Please note that DEFRA operate the official air quality forecast system for public information in the UK.
The AIITS Cloud Probe aboard the NASA Global Hawk.
NCAS Scientist, Dr James Dorsey from the University of Manchester has been working to develop a cloud probe from concept to prototype, which is now flying on board the NASA Global Hawk.
The Aerosol Ice Interface Transition Spectrometer, or AIITS was jointly developed by UK’s Universities of Hertfordshire and Manchester. It measures particles including dust, water droplets and ice crystals and allows the scientists to measure the scattering properties of tiny particles in the air (aerosols) and cirrus clouds. Scientists expect these measurements, combined with others to provide valuable new information about the formation and impact of extensive, thin cirrus clouds in the tropical tropopause layer. These clouds moderate transport of water vapour from the troposphere to the stratosphere, and have currently poorly understood effects on global climate.
Overall Winner at the NERC Impact Awards
NCAS Chief Scientist, Professor John Pyle FRS was honoured in the inaugural NERC Impact Awards at a ceremony earlier this week as the overall winner. Professor Pyle and Dr Neil Harris were rewarded for a large body of work that has led to a greater understanding of the depletion of ozone in the stratosphere. This work followed the suggestion in the 1970s that man-made compounds could deplete ozone, and the subsequent discovery of the Antarctic ozone hole in 1985.
Professor Pyle and Dr Neil Harris' work influenced the Montreal Protocol which ensured the rapid phase-out of ozone-depleting substances. As a result, the hole in the ozone now appears to be slowly closing, preventing a number of UV-related health problems worldwide, including skin cancer, sunburn and cataracts.
