Roof Frames in the Built Heritage of Brussels (Belgium) : the contribution of dendrochronology and written sources
No full textThis publication is a result of the 14th TRACE conference (Tree Rings in Archaeology, Climatology and Ecology) organized by the Department Physical, Chemical and Natural Systems of the University Pablo de Olavide (UPO) and the Association for Tree-ring Research (ATR), in collaboration with Pyrenean Institute of Ecology-Spanish National Research Council (IPE-CSIC), University of Barcelona (UB), Forest and Wood Technology Research Centre (CETEMAS) and University of Valladolid (UVa). The TRACE 2015 conference was held on May 20-23, 2015 for the first time in the Iberian Peninsula, in Sevilla, Spain
SO2 emissions derived from TROPOMI observations over India using a flux-divergence method with variable lifetimes
Get PDFThe rapid development of the economy and the implementation of environmental policies adapted in India have led to fast changes of regional SO2 emissions. We present a monthly SO2 emission inventory for India covering December 2018 to November 2023 based on the Tropospheric Monitoring Instrument (TROPOMI) Level-2 COBRA SO2 dataset, using an improved flux-divergence method and estimated local SO2 lifetime, which includes both its chemical loss and dry deposition. We update the methodology to use the daily CAMS model output estimates of the hydroxyl-radical distribution as well as the measured dry deposition velocity to account for the variability in the tropospheric SO2 lifetime. It is the first effort to derive the local SO2 lifetime for application in the divergence method. The results show the application of the local SO2 lifetime improves the accuracy of SO2 emissions estimation when compared to calculations using a constant lifetime. Our improved flux-divergence method reduced the spreading of the point-source emissions compared to the standard flux-divergence method. Our derived averaged SO2 emissions covering the recent 5 years are about 5.2 Tg yr−1 with a monthly mean uncertainty of 40 %, which is lower than the bottom-up emissions of 11.0 Tg yr−1 from CAMS-GLOB-ANT v5.3. The total emissions from the 92 largest point-source emissions are estimated to be 2.9 Tg yr−1, lower than the estimation of 5.2 Tg yr−1 from the global SO2 catalog MSAQSO2LV4. We claim that the variability in the SO2 lifetime is important to account for in estimating top-down SO2 emissions

The Influence of Climate Change and Interior Insulation on Salt Damage in Masonry Facades
No full textSalt-induced deterioration is a prominent concern when assessing the degradation risk associated with masonry facades. While there exists a substantial amount of knowledge about the mechanics of salt behaviour, quantitative assessment of this risk remains a challenge. Previous literature predominantly focuses on the evaluation of single salts; however in reality, masonry walls often feature a mixture of different salt types. Salt damage occurs as a consequence of recurrent crystallization-dissolution cycles, exerting substantial pressure on the pore surfaces of stones. Relative humidity is a fundamental driving factor for the amount and behaviour of the crystallization-dissolution cycles. This paper combines the findings derived from research on the kinetics of typical salt mixtures present in heritage buildings in Belgium with the outcomes of hygrothermal simulations. Heath-,Air- andMoisture (HAM) modelling provide relevant insights into the interaction between climate change, interior insulation, salt damage, and the hygrothermal characteristics of masonry constructions. The primary objective is to investigate the impact of climate change and interior insulation on salt damage, as both factors have the capacity to drastically change the hygrothermal behaviour of masonry walls. The results of this investigation underscore the significant influence of climate change and interior insulation on salt behaviour within masonry facades. The paper highlights the risks inherent in preserving historical masonry structures when subjected to retrofits or changing climatic conditions. It proves the necessity for adaptive preservation strategies in response to challenges faced
