Current environmental challenges invite us to deeply revise policies, governance models, and resource management toolkits towards a circular approach, in order to meet Sustainable Development Goals (SDGs) requirements. In this framework, circular waste management is one of the pillars of responsible and foresighted planning for territorial sustaina...

Plain Language Summary Lakes can have profound impacts on local precipitation, and such impacts are influenced by a variety of factors including the lake's geographical location, its size, and its depth. If only because of its sheer size, the question of how Lake Baikal, the largest and deepest freshwater lake in the world, affects the local climat...

Carbon monoxide poisoning (COP) from 2 to 9 October 2019 was a majorpublic health concern in Ulaanbaatar, Mongolia, after a transition from con-sumption of raw coal to upgraded briquette fuel. During the period, a total of 186 residents, which is 16 times more than the previous years, were exposed to COP and 6 persons died at home. We conduct a cro...

Diurnal variations in the lakes’ impact on the atmosphere are found through changing the surface energy budget, which includes changes in se...

The engineering project course in the form of project-based learning at GMIT, Mongolia, is adapted from the engineering program at the Technical University of Darmstadt and has been implemented since 2014. The transition from traditional to online learning during COVID-19 pandemic disrupted the engineering education process. Due to COVID-19 pandemi...

The study aims to reveal the impact of three sequential strict-lockdowns of COVID-19 measures on the air pollutants including NO2, SO2, PM10, and PM2.5 in Ulaanbaatar, Mongolia during November 2020–February 2021 based on air quality network and satellite data. Based on measurements of automatic air quality sites in Ulaanbaatar, we found a substanti...

Mongolia’s capital Ulaanbaatar experienced rapid growth after the country’s democratic revolution in the early 1990s. The increase in population outpaced the expansion of the city’s infrastructures and led to fragmentation between urban and peri-urban areas. A combination of unplanned urban sprawl, deficits in water and energy infrastructures, and...

Mining constitutes an integral part Mongolia’s national economy and dominates the country’s export revenue. At the same time, a wide range of mining on soil, water resources and the biosphere have been documented in Mongolia. This case study addresses the long-term impacts of mining on soil degradation at two mining sites located in the semiarid st...

For the last decades, Mongolia has seen an extensive escalation in population growth, urbanization, and industrialization, together with great increase in mining and usage of vehicles. As a result, a substantial increase has taken place in the types and number of emission sources of air pollutants, especially in urban areas. During the cold season,...

Ulaanbaatar, the capital city of Mongolia, has occasionally been considered the most polluted city in the world. Approximately 46% of the population resides in Ulaanbaatar, and over half of the population living in ger (traditional yurt dwelling) areas consumes raw coal, which leads to an increase in ambient air pollutants. The Government of Mongol...

A new version of 1D thermodynamic and hydrodynamic model LAKE 2.1 is presented. The model is supplemented with description of dynamics and vertical distribution of salinity in ice layer. Simulation results are compared to in situ and satellite data on water temperature and ice cover at Lake Uvs (Mongolia) from 2000 to 2015. We demonstrate that unde...

A new version of the one-dimensional thermo-hydrodynamic and biogeochemical model LAKE2.1 is presented. The model is supplemented with a description of the dynamics and vertical distribution of salinity in an ice cover. Simulation results are compared to in situ and satellite data of water temperature and ice cover at Uvs Nuur Lake (Mongolia) from...

This study analyzes a regional dust storm event that occurred in spring 2016 using data from observation sites, Lidar measurements, and satellite imageries. PM 10 concentrations at surface observation stations are considered as a primary indicator of the dust events. The dust events occurred on 3-12 March with PM 10 reaching a maximum beyond 1682,...

Urban breeze circulation (UBC) is a thermally forced mesoscale circulation, which is characterized by low-level inward flow toward the urban center, updrafts near the urban center, upper-level outward flows, and weak downdrafts outside the urban area. Previous numerical modeling studies indicate that in the early morning the direction of UBC can be...

Many big cities around the world are located near mountains. In city-mountain regions, thermally and topographically forced local winds are produced and they affect the transport of pollutants emitted into the urban atmosphere. A better understanding of the dynamics of thermally and topographically forced local winds is necessary to improve the pre...
