The composting facility at Eruemu has been appraised with particular reference to its impact on the Nitrogen dioxide and microbial load in air within and around the facility. Previous assessment of the ambient air within this facility indicated that its o... see more

For the first time, maps of surface concentration of nitrogen dioxide (NO2) are presented for the Colombian territory. NO2 surface concentrations for the year 2007 are inferred based on two sources of tropospheric NO2 column data: (1) a simulation using a... see more

The use of satellite data in combination with ground-based measurements can provide valuable information about atmospheric chemistry and air quality. In this study, ground-based Differential Optical Absorption Spectroscopy (DOAS) measurements of nitrogen ... see more

In this work we present the evolution of tropospheric nitrogen dioxide (NO2) content over several important European cities during 2005–2014 using space observations and ground-based in-situ measurements. The NO2 content was derived using the daily observ... see more

An instrument based on the Multi Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) technique was designed and constructed to measure scattered sunlight in the UV-visible region at different elevation angles. Slant column densities (SCDs) of spe... see more

Air quality monitoring in urban areas is indispensable in understanding the environment and how anthropogenic factors contribute to the increasing volume of pollutants in the atmosphere. Differential optical absorption spectroscopy (DOAS) is a useful tech... see more

The paper presents the results of theoretical calculations of the efficiency of the use of fuel (biogas) hf. The calculation of the theoretical temperature of the combustion of fuel is carried out. Calculated emissions of nitrogen oxides NOx and carbon di... see more
