The focus was on emissions of carbon dioxide, methane, nitrous oxide and black carbon.<\/span><\/span><\/p>\n<p><span><span>Although these inventories recorded the same emission peaks for particularly fire-affected years in the region (2007, 2012 and 2017), the comparison showed <strong>significant differences in quantifying GHG and black carbon emissions<\/strong>. \u2018Discrepancies in emissions were attributed to differences in fire detection methods, spatial resolutions, and emission factor assumptions.\u2019 &#8211; explains <a href=\"https:\/\/www.isac.cnr.it\/en\/users\/rabia-ali-hundal\">Rabia Ali Hundal<\/a>, author of the study and PhD student at the Scuola Universitaria Superiore Pavia and the University of Urbino and associate at CNR-ISAC &#8211; \u2018These discrepancies underscore the need for harmonised methodologies to improve the reliability of emission estimates.\u2019<\/span><\/span><\/p>\n<p><span><span>&nbsp;<\/span><\/span><\/p>\n<p><span><span>The researchers also noted that the years with peak emissions due to open vegetation fires in the Mediterranean were characterised by La Ni\u00f1a events, the cold counterpart of El Ni\u00f1o and which together constitute an oscillatory phenomenon (El Ni\u00f1o Southern Oscillation, ENSO) affecting the Pacific Ocean and atmosphere and capable of conditioning the global climate in the short term.<\/span><\/span><\/p>\n<p><span><span>In this sense, \u2018<strong>ENSO may have played a role<\/strong> in determining part of the observed inter-annual variability of GHG and BC emissions associated with open vegetation fires in the Mediterranean region,\u2019 the study states. \u2018However, due to the rather short period considered in our analysis work and the complex interactions of several factors influencing the occurrence of forest fires in the Mediterranean, further and more specific studies are needed to consolidate this possible relationship,\u2019 Hundal continues.<\/span><\/span><\/p>\n<p><span><span>&nbsp;<\/span><\/span><\/p>\n<p><span><span>This research underlines the importance of improving systems to quantify emissions and support research in this direction. Future studies could in fact develop consistent methodologies, integrating satellite and ground-based data and using systems already used in other emission sectors. \u2018In particular, what we suggest is that top-down emission assessment techniques could also be attempted for open vegetation fires, i.e. based on the combined use of atmospheric concentration data of climate-altering substances collected from ground and satellite stations with simulations of atmospheric transport,\u2019 &#8211; explains <a href=\"https:\/\/www.isac.cnr.it\/en\/users\/paolo-cristofanelli\">Paolo Cristofanelli<\/a> of CNR-ISAC, author of the study &#8211; \u2018This would allow <strong>independent estimates<\/strong> to be compared with the numbers provided by inventories such as those we analysed in our work.\u2019<\/span><\/span><\/p>\n<p><span><span>&nbsp;<\/span><\/span><\/p>\n<p><span><span>Improving emission inventories would therefore allow the development of evidence-based strategies for fire prevention and effective climate change mitigation, especially at the local and regional level.<\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new study found discrepancies among four state-of-the-art emission inventories.
