  • Methane is a powerful greenhouse gas and previous studies focus on its sources with less attention on the loss. Here the authors show that reactive halogen species, not considered in climate projections, significantly reduces the methane loss, increasing its lifetime, burden, and radiative forcing.

  • External cycling regenerates nitrogen oxides from the NOx oxidative reservoir, NOz. Aircraft observations reveal NOx external cycling compensates for NOx aging, sustaining NOx distribution and production of OH radicals far from NOx emission sources

  • High ozone and low water structures in the tropical western Pacific are commonly attributed to transport from the stratosphere or mid-latitudes. Here, Anderson et al. show these structures actually result from ozone production in biomass burning plumes and large-scale descent of air within the tropics.

  • Chlorine radicals function as a strong atmospheric oxidant, particularly in polar regions, where levels of hydroxyl radicals are low. Measurements in the Arctic reveal high levels of molecular chlorine during the day, consistent with a photochemical source.

  • Aircraft measurements, laboratory photolysis experiments and modelling calculations reveal a mechanism for the recycling of nitric acid into nitrogen oxides; this enables observations to be reconciled with model studies, and suggests that particulate nitrate photolysis could be a substantial tropospheric nitrogen oxide source.

  • A wide variety of enzymatic pathways that produce specialized metabolites in bacteria, fungi and plants are known to be encoded in biosynthetic gene clusters. Information about these clusters, pathways and metabolites is currently dispersed throughout the literature, making it difficult to exploit. To facilitate consistent and systematic deposition and retrieval of data on biosynthetic gene clusters, we propose the Minimum Information about a Biosynthetic Gene cluster (MIBiG) data standard.
