Accounting and reporting of greenhouse gas (GHG) emissions are mandatory for Parties under the Paris Agreement. Emissions is important understanding global carbon cycle addressing climate change. However, in a period open conflict or war, military increase significantly accounting system not currently designed to account adequately this source. In paper we analyze how, during first 18 months 2022/2023 full-scale war Ukraine, GHG national inventory UNFCCC was affected. We estimated decrease...
Emission inventories (EIs) are the fundamental tool to monitor compliance with greenhouse gas (GHG) emissions and emission reduction commitments. Inventory accounting guidelines provide best practices help EI compilers across different countries regions make comparable, national estimates regardless of differences in data availability. However, there a variety sources error uncertainty that originate beyond what inventory can define. Spatially explicit EIs, which key product for atmospheric...
Abstract Knowledge of the spatial distribution agricultural abandonment following collapse Soviet Union is highly uncertain. To help improve this situation, we have developed a new map arable and abandoned land for 2010 at 10 arc-second resolution. We fused together existing cover use maps different temporal scales former (fSU) using training data set collected from visual interpretation very high resolution (VHR) imagery. also an independent validation to assess accuracy. The overall...
Abstract. A severe reduction of greenhouse gas emissions is necessary to reach the objectives Paris Agreement. The implementation and continuous evaluation mitigation measures requires regular independent information on two main anthropogenic gases, carbon dioxide (CO2) methane (CH4). Our aim employ an observation-based method determine regional-scale emission estimates with high accuracy. We use aircraft- ground-based in situ observations CH4, CO2, monoxide (CO), wind speed from research...
Greenhouse gas (GHG) inventories at national or provincial levels include the total emissions as well for many categories of human activity, but there is a need spatially explicit GHG emission inventories. Hence, aim this research was to outline methodology producing high-resolution inventory, demonstrated Poland. sources were classified into point, line, and area types then combined calculate emissions. We created vector maps all economic activity covered by IPCC guidelines, using official...
The assessment of greenhouse gases (GHGs) and air pollutants emitted to removed from the atmosphere ranks high on international political scientific agendas. Growing concern cooperation regarding climate change problem have increased need consider uncertainty in inventories GHG emissions. approaches address discussed this special issue reflect attempts improve national inventories, not only for their own sake but also a wider, system analytic perspective. They seek strengthen usefulness...
Agricultural activity plays a significant role in the atmospheric carbon balance as source and sink of greenhouse gases (GHGs) has high mitigation potential. The agricultural emissions display evident geographical differences regional, national, even local levels, not only due to spatially differentiated activity, but also very geographically different emission coefficients. Thus, resolved inventories are important for obtaining better estimates content design GHG processes adapt global rise...
Abstract Since February 2022, the full-scale war in Ukraine has been strongly affecting society and economy beyond. Satellite observations are crucial tools to objectively monitor assess impacts of war. We combine satellite-based tropospheric nitrogen dioxide (NO 2 ) carbon (CO detect characterize changes human activities, as both linked fossil fuel combustion processes. show significantly reduced NO levels over major Ukrainian cities, power plants industrial areas: concentrations second...
Vegetation acts as an essential land-based carbon sink, which can be affected by military conflicts and wars through landscape fires that cover large territories will lead to additional greenhouse gas (GHG) emissions into the atmosphere. To investigate this impact, we spatially analyzed effect of ongoing Russo–Ukrainian War on GHG from determined change sequestration capacity forests. Using remotely sensed data 2022–2023, first identified fire perimeters in territory...
A method for constructing Chebyshev approximation with relative error of the exponential from a rational expression is proposed. It implies an intermediate absolute by logarithm function being approximated. The calculated as boundary mean-power using iterative scheme based on least squares two variable weight functions. presented results solving test examples confirm fast convergence method.
Tracking spatiotemporal changes in GHG emissions is key to successful implementation of the United Nations Framework Convention on Climate Change (UNFCCC). And while emission inventories often provide a robust tool track trends at country level, subnational estimates are not reported or reports vary robustness as dependent spatial modeling approach and ancillary data used disaggregate inventories. Assessing errors uncertainties fundamentally challenging due lack physical measurements level....
The development of high-resolution greenhouse gas (GHG) inventories is an important step towards emission reduction in different sectors. However, most the spatially explicit approaches that have been developed to date produce outputs at a coarse resolution or do not disaggregate data by sector. In this study, we present methodology for assessing GHG emissions from residential sector settlements fine spatial resolution. many countries, statistical about fossil fuel consumption only available...
Industrial processes cause significant emissions of greenhouse gases (GHGs) to the atmosphere and, therefore, have high mitigation and adaptation potential for global change. Spatially explicit (gridded) emission inventories (EIs) should allow us analyse sectoral patterns estimate impacts policies support decisions on reducing emissions. However, such EIs are often based simple downscaling national level estimates changes in subnational distributions do not necessarily reflect actual driven...
Abstract CO 2 emissions from fossil fuel combustion (FFCO2) are conventionally estimated used (as activity data (AD)) and factor. Recent traffic emission changes under the impact of COVID-19 pandemic have been using emerging non-fuel consumption data, such as human mobility that tech companies reported AD, due to unavailability timely statistics. The use unconventional (UAD) might allow us provide estimates in near-real time; however, errors uncertainties associated with expected be larger...
Tank facilities storing various combustible substances are a potential source of danger for the environment and human life. Fires in tanks can occur reasons: technical malfunctions, factors, military operations, natural phenomena. One effective methods extinguishing such fires is "sublayer" with help foam low multiplicity. The possibility "sub-layer" compression foam, which has unique properties, been considered. object this study processes stopping combustion during fire steel storage...
