Big data and UN’s sustainable development goals

At present, better understanding of various interactions and feedbacks between Earth surface and atmosphere is required to improve climate related predictions and mitigation plans. Foremost, if the global CO2 emissions continue increasing at the current rate, we will have, within 40 years, atmospheric CO2 concentration over 500 ppm (www.esrl.noaa.gov/gmd/ccgg/trends/). This value can be considered to be critical … Continue reading Big data and UN’s sustainable development goals

Estimation of the tropospheric and stratospheric CO2 content by ground-based IR technique

Published: 05 July 2021; https://doi.org/10.1134/S0001433821020110 Measured solar spectra of high spectral resolution possess specific information about the vertical distribution of some atmospheric gases. The assessment of the spectra informational value is provided by determining a degree of freedom for signal (dofs). This can be obtained from the solar spectra. Such information can be used to … Continue reading Estimation of the tropospheric and stratospheric CO2 content by ground-based IR technique

Thunderstorms activity – concerns for aviation

Summary of research Thunderstorms are a common natural phenomenon that significantly affects a flight safety worldwide. In our study (with focus on the Kyiv International Airport – Zhuliany, Ukraine) in total 379 cases of thunderstorms were investigated for 2009–2018. The methodological approach included in depth weather-climatological analysis and numerical modeling of thunderstorm activity.

The Arctic Yearbook –a perfect platform for Arctic & global studies

The COVID-19 pandemic has forced us to consider globalization’s dark side by bringing up new premises of security due to environmental degradation, climate change and pandemics as non-military threats that should be applied comprehensively. It also supports an importance of scientific research & its applications, digitalization, distance-learning /-working, and open access material for knowledge-building, when … Continue reading The Arctic Yearbook –a perfect platform for Arctic & global studies

Snow and ice mass balance in the Finnish Arctic

The Arctic Amplification (AA) has a direct impact on Boreal lakes. The warmer air temperature and enhanced snow condition favour granular ice formation in boreal lakes. In order to better understand climate change on Lake Ice phenology, a thermistor string-based ice mass balance (IMB) buoy called SIMBA (http://digital.ecomagazine.com/display_article.php?id=3771615&view=674747) has been deployed in Orajärvi lake in … Continue reading Snow and ice mass balance in the Finnish Arctic
