Integrative and comprehensive Understanding on Polar Environments (iCUPE): the concept and initial results

Abstract

The role of polar regions increases in terms of megatrends such as globalization, new transport routes, demography and use of natural resources consequent effects of regional and transported pollutant concentrations. We set up the ERA-PLANET Strand 4 project "iCUPE -integrative and Comprehensive Understanding on Polar Environments" to provide novel insights and observational data on global grand challenges with an Arctic focus. We utilize an integrated approach combining 55 in situ observations, satellite remote sensing Earth Observations (EO) and multi-scale modeling to synthesize data from comprehensive long-term measurements, intensive campaigns and satellites to deliver data products, metrics and indicators to the stakeholders concerning the environmental status, availability and extraction of natural resources in the polar areas. The iCUPE work consists of thematic state-of-the-art research and provision of novel data in atmospheric pollution, local sources and transboundary transport, characterization of arctic surfaces and their changes, assessment of concentrations and impacts 60 of heavy metals and persistent organic pollutants and their cycling, quantification of emissions from natural resource extraction and validation and optimization of satellite Earth Observation (EO) data streams. In this paper we introduce the iCUPE project and summarize initial results arising out of integration of comprehensive in situ observations, satellite remote sensing and multiscale modeling in the Arctic context. 65

Unmanned Aerial Systems for Investigating the Polar Atmospheric Boundary Layer—Technical Challenges and Examples of Applications

“…In this section, three different types of UAS of the Institute of Flight Guidance, TU Braunschweig, with different meteorological payloads are introduced. They were applied in the polar areas in the time period 2013 to 2018 [16][17][18]. Each system is presented in the following, and a quick overview of the performed polar campaigns is provided, summarized in Table 1.…”

“…ALADINA was used as a link between different aerosol observatories in Svalbard (Norway). Research flights were performed in spring 2018 at the airfield in Ny-Ålesund and first results are presented in [18]. The research village of Ny-Ålesund is located at Kongsfjord and surrounded by mountains up to 700 m ASL and glaciers.…”

Research agenda for the Russian Far East and utilization of multi-platform comprehensive environmental observations

“…In order to address these changes, provision of observational data in the Arctic region has been identified as a key requirement in the Arctic Observation Summit (AOS) by Sustaining Arctic Observation Network (SAON, e.g. Murray et al 2020) including the marine (Vihma et al 2019) and comprehensive atmospheric observations (Hari et al 2016;Uttal et al 2016) as well as integration of in-situ and satellite remote sensing (Petäjä et al 2020).…”

Institute for Atmospheric and Earth System Research (INAR): Showcases for making science diplomacy

“…Collaborative research in Russia has been focused on CC, AQ, dynamics of the land-atmosphere interactions and feedbacks covering topics like permafrost thawing, greenhouse gas (GHG) emissions and sink processes, aerosol formation, environmental health and Artic greening and browning (e.g. Paasonen et al, 2013;Ezhova et al, 2018Ezhova et al, , 2020Petäjä et al, 2020). In China, INAR's collaboration interest has been on understanding the complex air pollution cocktail (Kulmala, 2015) including feedbacks with boundary layer processes and atmospheric aerosol population (Ding et al, 2016a;Petäjä et al, 2016), particularly in the most polluted megacity environments.…”
