MAX-DOAS observations of spatial variability of NO2 in Athens

Nitrogen dioxide is a key pollutant in the troposphere. Most of its sources are anthropogenic and linked to the burning of fossil fuels, but wildfires, lightning and soil emissions also contribute to the overall NOx (NO + NO2) loading.Using passive remote sensing in the UV and visible spectral range, NO2 columns can be retrieved with both ground-based ...

MAX-DOAS observations of pollutant distribution and transboundary transport in typical regions of China

Journal of Environmental Sciences
Studying the spatiotemporal distribution and transboundary transport of aerosols, NO2, SO2, and HCHO in typical regions is crucial for understanding regional pollution causes. In a 2-year study using multi-axis differential optical absorption spectroscopy in Qingdao, Shanghai, Xi'an, and Kunming, we investigated pollutant distribution and transport ...

MAX-DOAS measurements of air pollution on the northern tip of Taiwan

Wind and weather in Taiwan are strongly influenced by the monsoons. Taiwan is on the lee side of the Asian winter monsoon, originating on the Asian continent. It receives continental air masses transported by the monsoon, thus air pollutants originating in the eastern and northern parts of China. While polluted air reaches Taiwan during winter monsoon,

MAX-DOAS Measurements in Rural and Suburban regions of New Zealand

New Zealand is primarily made of two islands with a total population of around 5 Million.  The smaller North Island contains a higher population including New Zealand's largest city of Auckland with approximately 1.5 million residents, while the larger South Island contains a much smaller population and is largely rural.  Lauder on ...

Detecting lightning NOx from ship-borne MAX DOAS measurements

Transit cruises of German research vessels across the great oceans provide a unique platform for Multi AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) measurements of atmospheric trace gases such as nitrogen dioxide (NO2), formaldehyde (HCHO) and sulphur dioxide (SO2) in pristine locations. Here, we present results of the Extra Atmospheric
