Richard is one of ten innovators who have been awarded a total of £1.5 million through the Natural Environment Research Council (NERC) knowledge exchange (KE) fellowships. The three-year KE fellowships are designed to enable the sharing, flow and translation of knowledge and expertise between NERC-remit researchers and the research sector, businesses, policymakers and the public. TOMCAT...
PhD student Emily Dowd achieved the most-viewed BBC Science article on the BBC Website on 16/9/2023: Major UK methane greenhouse gas leak spotted from space. The story relates to Emily's use of GHGSat satellite data to discover a natural gas leak from a pipeline near Cheltenham. This received widespread media attention and is now published...
Luana Basso's recent TOMCAT inversion model study in Atmos Chem Phys has been selected as an Editor's highlight. The Editor's citation is: "The Amazon's role in the tropical and global carbon cycle is highly significant. Usually considered as the "lung of the planet", it is mandatory to monitor if this role is kept, or if...
Wuhu Feng's recent GRL paper on iodine propulsion is highlighted in Nature article. Feng, W., J.M.C. Plane, M.P. Chipperfield, A. Saiz-Lopez and J.-P. Booth, Potential stratospheric ozone depletion due to iodine injection from small satellites, Geophys. Res. Lett., 50, e2022GL102300, doi:10.1029/2022GL102300, 2023.
The latest (2022) WMO/UNEP quadrennial ozone assessment has been published. It concludes that the ozone layer is on track to recover within four decades, with the global phaseout of ozone-depleting chemicals already benefitting efforts to mitigate climate change. The report from a UN-backed panel of experts was presented at the American Meteorological Society’s 103rd annual...
No ozone hole in the tropics! We have just led and published a strong rebuttal of a paper in AIP Advances which claimed that there (Chipperfield et al., 2022). That paper had not only claimed large ozone depletion in the tropics but gave an erroneous mechanism for polar ozone depletion. Chipperfield, M.P., A. Chrysanthou, R....
Stephen Anderson, Marco Gonzalez and Nancy Sherman have written an EOS article on the Montreal Protocol, highlighting twelve papers which formed "the scientific basis for fast action to strengthen the treaty, which was already safeguarding stratospheric ozone, so it also protects the climate by reducing super pollutants.". One of the 12 papers is our study...
Emily's talk at ESA Living Planet symposium highlighted. (ESA story). Emily was presenting work that is now published in her Atmos. Chem. Phys. paper. Dowd, E., C. Wilson, M.P. Chipperfield, E. Gloor, A. Manning and R. Doherty, Decreasing seasonal cycle amplitude of methane in the northern high latitudes being driven by lower latitude changes...
The emissions of a banned ozone-depleting gas have dropped rapidly following a previously unexpected spike. A team of international researchers analysed global air measurements of the ozone-depleting chemical chlorofluorocarbon CFC-11. The analysis involved the use of detailed atmospheric models to remove the effects of natural meteorological variations. They found that five years after an unexpected...
Rising nitrous oxide emissions are jeopardizing climate goals and the Paris Accord, according to a new international study, which included results from TOMCAT (INVICAT) inversions. The growing use of nitrogen fertilizers in the production of food worldwide is increasing concentrations of nitrous oxide in the atmosphere—a greenhouse gas 300 times more potent than carbon dioxide—which...
