title: Global Sensitivity And Uncertainty Analysis Of An Atmospheric Chemistry Transport Model: The Frame Model (Version 9.15.0) As A Case Study

description: Atmospheric chemistry transport models (ACTMs) are widely used to underpin policy decisions associated with the impact of potential changes in emissions on future pollutant concentrations and deposition. It is therefore essential to have a quantitative understanding of the uncertainty in model output arising from uncertainties in the input pollutant emissions. ACTMs incorporate complex and non-linear descriptions of chemical and physical processes which means that interactions and non-linearities in input–output relationships may not be revealed through the local one-at-a-time sensitivity analysis typically used. The aim of this work is to demonstrate a global sensitivity and uncertainty analysis approach for an ACTM, using as an example the FRAME model, which is extensively employed in the UK to generate source-receptor matrices for the UK Integrated Assessment Model and to estimate critical load exceedances. An optimised Latin hypercube sampling design was used to construct model runs within ± 40 % variation range for the UK emissions of SO<sub>2</sub>, NO<sub>x</sub> and NH<sub>3</sub>, from which regression coefficients for each input-output combination and each model grid (&gt;10,000 across the UK) were calculated. Surface concentrations of SO<sub>2</sub>, NO<sub>x</sub> and NH<sub>3</sub> (and of deposition of S and N) were found to be predominantly sensitive to the emissions of the respective pollutant, while sensitivities of secondary species such as HNO<sub>3</sub> and particulate SO<sub>4</sub><sup>2-</sup>, NO<sub>3</sub><sup>-</sup> and NH<sub>4</sub><sup>+</sup> to pollutant emissions were more complex and geographically variable. The uncertainties in model output variables were propagated from the uncertainty ranges reported by the UK National Atmospheric Emissions Inventory for the emissions of SO<sub>2</sub>, NO<sub>x</sub> and NH<sub>3</sub> (± 4 %, ± 10 % and ± 20 % respectively). The uncertainties in the surface concentrations of NH<sub>3</sub> and NO<sub>x</sub> and the depositions of NH<sub>x</sub> and NO<sub>y</sub> were dominated by the uncertainties in emissions of NH<sub>3</sub>, and NO<sub>x</sub> respectively, whilst concentrations of SO<sub>2</sub> and deposition of SO<sub>y</sub> were affected by the uncertainties in both SO<sub>2</sub> and NH<sub>3</sub> emissions. Likewise, the relative uncertainties in the modelled surface concentrations of each of the secondary pollutant variables (NH<sub>4</sub><sup>+</sup>, NO<sub>3</sub><sup>-</sup>, SO<sub>4</sub><sup>2-</sup> and HNO<sub>3</sub>) were due to uncertainties in at least two input variables. In all cases the spatial distribution of relative uncertainty was found to be geographically heterogeneous. The global methods used here can be applied to conduct sensitivity and uncertainty analyses of other ACTMs.

The dataset contains model outputs used for the sensitivity and uncertainty analyses.

title: Data used in the manuscript entitled "Turbulent heat flux dynamics along the Dotson and Getz ice-shelf fronts (Amundsen Sea, Antarctica)"

description: Data files used in the analysis in the manuscript entitled "Turbulent heat flux dynamics along the Dotson and Getz ice-shelf fronts (Amundsen Sea, Antarctica)".

Data were collected during the RV NB Palmer NBP2202 cruise, during the 2022 TARSAN campagine in the Amundsen Sea.

Underway data provides daily files from the underway and meteorology sensors in JGOFS format. CTD data collected from the cruise. Information about sensors and data formats is included in the data report.

Glider data was processed through the UEA Seaglider Toolbox (https://bitbucket.org/bastienqueste/uea-seaglider-toolbox/src/toolbox/) and is provided in Matlab format.

 

Manuscript abstract:

In coastal polynyas, where sea–ice formation occurs, it is crucial to have accurate estimates of heat fluxes in order to predict future rates of sea–ice formation. The Amundsen Sea Polynya is the fourth largest coastal polynya around Antarctica, yet remains poorly observed because of its remoteness. Consequently, we rely on models and reanalysis that are unvalidated to study the effect of atmospheric forcing on polynya dynamics. We use summer ship-board data from the NBP22/02 cruise to understand the turbulent heat flux dynamics in the Amundsen Sea Polynya and evaluate our ability to represent these dynamics in ERA5. We show that cold and dry air outbreaks from Antarctica enhance air–sea temperature and humidity gradients, triggering episodic heat loss events. The heat loss is larger along the ice shelves, and it is also where the ERA5 turbulent heat flux exhibits the largest biases, underestimating the flux by up to 141~W~m$^{-2}$ due to its coarse resolution and misrepresentation of ice-shelf location. By reconstructing a turbulent heat flux product from ERA5 variables using a nearest neighbour approach to obtain sea surface temperature, we decrease the bias to 107 W m$^{-2}$. Using a 1D-model, we show that the mean co-located ERA5 heat loss underestimation of -28~W~m$^{-2}$ led to an overestimation of the summer evolution of sea surface temperature (heat content) by +0.76~°C (+8.2e+07~J) over 35-days. By obtaining the reconstructed flux, the reduced heat loss bias (12 W~m$^{-2}$) reduced the seasonal bias in sea surface temperature (heat content) to -0.17~°C (-3.30e+07~J) over the 35-days. This study shows that caution should be applied when retrieving ERA5 turbulent flux along the ice shelves, and that a reconstructed flux using ERA5 variables shows better accuracy.

title: In situ study of Magnesiothermic reduction (MgTR)

description: SiOx is one of the most promising materials to increase the capacity of anodes for next-generation Lithium-ion Batteries (LIBs), with theoretical storage
 capacities of up to 2400 mAhg-1. However, the stability and storage capacity of SiOx anodes depends on its oxygen content, and therefore the development
 of synthesis routes for the controlled synthesis of SiOx compounds with tailored oxygen content is imperative. MagnesioThermic reduction (MgTR) has been
 pinpointed as a scalable method to produce SiOx from Mg and SiO2 using much lower temperatures (500-950ºC) than conventional methods. However, synthesis
 temperature, reaction time and stoichiometry of the reactants strongly affect reaction pathways and prevents the controlled synthesis of SiOx compounds with
 adjusted oxygen content. Hence, in situ analysis of the MgTR via X-ray diffraction is critical to design an effective strategy for the synthesis of high-performance
 SiOx electrodes for LIBs.

title: Global Register of Introduced and Invasive Species - Ukraine

description: The Global Register of Introduced and Invasive Species (GRIIS) presents validated and verified national checklists of introduced (alien) and invasive alien species at the country, territory, and associated island level. Checklists are living entities, especially for biological invasions given the growing nature of the problem. GRIIS checklists are based on a published methodology and supported by the Integrated Publishing Tool that jointly enable ongoing improvements and updates to expand their taxonomic coverage and completeness. Phase 1 of the project focused on developing validated and verified checklists of countries that are Party to the Convention on Biological Diversity (CBD). Phase 2 aimed to achieve global coverage including non-party countries and all overseas territories of countries, e.g. those of the Netherlands, France, and the United Kingdom. All kingdoms of organisms occurring in all environments and systems are covered. Checklists are reviewed and verified by networks of country or species experts. Verified checklists/ species records, as well as those under review, are presented on the online GRIIS website (www.griis.org) in addition to being published through the GBIF Integrated Publishing Tool.

title: Continuous velocity model for Johnsons and Hurd glaciers from 1999 to 2013, with link to model results in shapefile and MS Excel format

description: Data velocity ice in the glacier surface are critical for glacier dynamics models. Although not generally used as boundary conditions inhomogeneous (as, instead, is usually set boundary conditions of homogeneous Neumann type of zero traction on the surface) Dirichlet type, surface speeds are used to adjust free model parameters such as the coefficient B of the constitutive relation or the multiplicative factor that usually appears in the parameterization of Weertman type of basal sliding velocity, so to minimize the differences between the speeds observed and calculated by the model on the surface.

title: WASCAL WRF60km with GFDL-ESM r1i1p1 forcing from the CMIP5 RCP4.5 experiment

description: Project: West African Science Service Centre on Climate Change and Adapted Land Use - With climate change being one of the most severe challenges to Africa in the 21st century, West Africa is facing an urgent need to develop effective adaptation and mitigation measures. WASCAL (West African Science Service Centre on Climate Change and Adapted Land Use, http://www.wascal.org) is a large-scale research-focused Climate Service Centre designed to help tackle this challenge and thereby enhance the resilience of human and environmental systems to climate change and increased variability. It does so by strengthening the research infrastructure and capacity in West Africa related to climate change and by pooling the expertise of ten West African countries and Germany. Funded by the German Federal Ministry of Education and Research (BMBF), WASCAL is implemented in a collaborative effort by West African and German partners. An integral part of its climate services is the provisioning of a new set of high resolution, ensemble-based regional climate change scenarios for the region of West Africa. An ensemble approach is chosen to address model uncertainties and provide statistical estimates on possible future climate change scenarios. The ensemble is composed of three regional climate models, WRFV3.5.1, COSMO-CLM 4.18, and REGCM4. Three Earth System Models from the CMIP5 project are downscaled by each of the regional models, MPI-ESM, GFDL-ESM2M, and HadGEM2-ES for the historical period from 1980 to 2010 and for the RCP4.5 scenario from 2020 to 2050 and from 2070 to 2100. Control runs are created by downscaling the European Centre for Medium-Range Weather Forecasts ERA-Interim re-analysis from 1980 to 2014. Two sets of resolutions are made available, 60km and 12km, for a large domain covering the greater region of West Africa from 25W to 25E and 5S to 25N. Summary: This experiment (2006-2100) uses 'CMIP5 GFDL r1i1p1 rcp45' forcing data for downscaling to 60km resolution by the regional model WRFV3.5.1 for the region of West Africa. 'rcp45' is an experiment of the CMIP5 - Coupled Model Intercomparison Project Phase 5 (https://pcmdi.llnl.gov/mips/cmip5). 4.1 rcp45 (4.1 RCP4.5) - future projection (2006-2300) forced by RCP4.5. Experiment design:https://cera-www.dkrz.de/WDCC/ui/Entry.jsp?acronym=Taylor_CMIP5_design.pdf . This experiment is divided into several time slices of 11 years. The first year of each time slice is used as a spin-up phase and should not be used in the analysis. All experiments with GFDL forcing refer to a calendar with 365 days (noleap). The 60 km resolution of this experiment is an intermediate step to the 12km downscaling WRF experiment.
