Abstract
The development of oil and gas drilling and the opening of new shipping routes, in the Barents and Norway seas, poses new challenges for the Arctic environment due to the impact of air pollution emissions on climate and air quality. To improve our knowledge of the interactions between aerosols, water vapor and cloud cover, within the French PARCS (Pollution in the ARCtic System) project, Raman lidar observations were performed from the ground and from an ultra-light aircraft near the North Cape in northern Norway, and coupled with measurements from a 95 GHz ground-based Doppler radar.
Highlights
The French Arctic initiative project Pollution in the ARCtic System (PARCS), aims to improve our knowledge about the impact of local pollution on the Arctic system, including cloud formation, and builds on past efforts that began in the 1980s [1]
2.1 Ground-based measurements The Mobile Atmospheric Station (MAS) was located close to the Hammerfest airport (Figure 1). It was equipped with the 354.7-nm water vapor Raman lidar (WALI) and the 95-GHz miniBASTA radar [3][4][5]
Water vapor and clouds were simultaneously sampled in the atmospheric column using ground-based and airborne lidars, coupled with a ground-based 95 GHz radar for clouds identification and microphysics
Summary
The French Arctic initiative project Pollution in the ARCtic System (PARCS), aims to improve our knowledge about the impact of local pollution on the Arctic system, including cloud formation, and builds on past efforts that began in the 1980s [1]. The experiment took place in May 2016 in the re io o ammer est It is based on the coupling between Raman lidar observations performed from both the ground and an ultralight aircraft (ULA) [2][3]. These observations make it possible to quantify aerosols, water vapor and to identify cloud types via a 95 GHz mini-radar (BASTA) / lidar synergy [4]. The main scientific objectives are to i) sample the aerosol pollution along the coast of northern Norway due to shipping, oil and gas extraction activities, ii) quantify the atmospheric pollution due to local flaring activities and industries, and iii) study the interactions between aerosols and water vapor, cloud liquid droplets, cloud ice crystals
