GESAMP - Reports and Studies, 97. The magnitude and impacts of anthropogenic atmospheric nitrogen inputs to the ocean
World Meteorological Organization (WMO) ; Food and Agriculture Organization (FAO); United Nations Educational, Scientific and Cultural Organization (UNESCO); et al. - WMO, 2018The present global modelling study of the Nr atmospheric cycle and Nr deposition to the ocean is the first that evaluates past, present and future Nr atmospheric deposition accounting for ON primary sources as well as for secondary ON chemical formation as a N-dependent process. While the total Nr deposition to the ocean is not expected to change significantly by 2050, the relative importance of oxidized and reduced N is expected to change, with an increasing proportion of ammonium compared to nitrate, resulting from more efficient controls on terrestrial emissions of nitrogen oxides (NOx) com ...

While the total Nr deposition to the ocean is not expected to change significantly by 2050, the relative importance of oxidized and reduced N is expected to change, with an increasing proportion of ammonium compared to nitrate, resulting from more efficient controls on terrestrial emissions of nitrogen oxides (NOx) compared to ammonia. This would result in a change in the acidity of the atmospheric deposition.

GORMP, 58. Scientific Assessment of Ozone Depletion: 2018
World Meteorological Organization (WMO) ; National Oceanic and Atmospheric Administration (NOAA); United Nations Environment Programme (UNEP); et al. - WMO, 2018The Assessment documents the advances in scientific understanding of ozone depletion reflecting the thinking of the many international scientific experts who have contributed to its preparation and review. These advances add to the scientific basis for decisions made by the Parties to the Montreal Protocol. It is based on longer observational records, new chemistry- climate model simulations, and new analyses.

IOM Report, 128. Interlaboratory Comparison in the field of Temperature, Humidity and Pressure, in the WMO Regional Association VI (MM-ILC-2015-THP)
The subject of this report is evaluation of the interlaboratory comparison in the field of measurement of temperature, humidity and pressure. The interlaboratory comparison was held within the framework of the MeteoMet 2 project, in the scope of proficiency testing scheme organized by the University of Ljubljana, Faculty of Electrical Engineering, Laboratory of Metrology and Quality (UL-FE/LMK), except pressure part. All the analysis were done in accordance with accredited procedures.Interlaboratory Comparison in the field of Temperature, Humidity and Pressure, in the WMO Regional Association VI (MM-ILC-2015-THP)

IOM Report, 130. Fourth WMO Regional Pyrheliometer Comparison of RA II, Jointly held with RA V
This report describes the intercomparison in detail: the instruments, the participants, the experimental setup, method and procedure, the data analysis technique used and the results. It is clear from the results that all of the participating instruments have been well maintained and remained stable since the previous intercomparison, which augers well for all radiation measurements within RA II and RA V. All participants were able to return home with newly derived WRR reduction factors for their instruments.Permalink![]()
