Long-term response of diatoms in high-elevation streams influenced by rock glaciers
Published 2022-11-01“…The novelty of this work is that covers a unique heterogeneous aquatic environment in the Alps affected by climate change, an area where the temperature has increased over twofold more than other regions in the northern hemisphere. This long-term study provides the opportunity of forecasting how other alpine freshwater ecosystems globally may change in the future. …”

Sensitivity of the interannual variability of mineral aerosol simulations to meteorological forcing dataset
Published 2017“…Because of the large variability, at least 1 year of observations at most sites are needed to correctly observe the mean, but in some regions, particularly the remote oceans of the Southern Hemisphere, where interannual variability may be larger than in the Northern Hemisphere, 2–3 years of data are likely to be needed.…”

Sulfuryl fluoride in the global atmosphere
Published 2011“…The global tropospheric background concentration of SO[subscript 2]F[subscript 2] has increased by 5 ± 1% per year from ∼0.3 ppt (parts per trillion, dry air mol fraction) in 1978 to ∼1.35 ppt in May 2007 in the Southern Hemisphere, and from ∼1.08 ppt in 1999 to ∼1.53 ppt in May 2007 in the Northern Hemisphere. The SO[subscript 2]F[subscript 2] interhemispheric concentration ratio was 1.13 ± 0.02 from 1999 to 2007. …”

TransCom N[subscript 2]O model inter-comparison – Part 2: Atmospheric inversion estimates of N[subscript 2]O emissions
Published 2014“…Emissions from the northern mid- to high latitudes are likely to be more important, with a consistent shift in emissions from the tropics and subtropics to the mid- to high latitudes in the Northern Hemisphere; the emission ratio for 0–30° N to 30–90° N ranges from 1.5 to 1.9 compared with 2.9 to 3.0 in previous estimates. …”

Atmospheric trace metals over the south-west Indian Ocean: Total gaseous mercury, aerosol trace metal concentrations and lead isotope ratios
Published 2010“…TGM was 1.05-1.51ngm-3 during the cruise (average 1.2ngHgm-3), towards the lower end of mercury levels observed over oceans in the northern hemisphere. The TGM data appears to show a concentration gradient over the cruise with increasing concentrations at more northern locations closer to the inter-tropical convergence zone. …”

Description and evaluation of aerosol in UKESM1 and HadGEM3-GC3.1 CMIP6 historical simulations
Published 2020“…Simulated aerosol number concentrations are generally within a factor of 2 of the observations, with both models tending to overestimate number concentrations over remote ocean regions, apart from at high latitudes, and underestimate over Northern Hemisphere continents. Finally, a new primary marine organic aerosol source is implemented in UKESM1 for the first time. …”

Climate impacts of stratospheric particle injection

These models fail to capture the observed NH dynamical response following eruptions, which is of concern for the accuracy of geoengineering modelling studies that assess the atmospheric response to sulphate aerosol geoengineering.…”
