- | Currently simulations are focusing on Research Flight 4 which took place on December 14th 2013, the main reason for this is due to the presence of an elevated moisture layer during the flight. During this flight there were 11 dropsondes launched. The LES are being run for the region around each dropsonde launch position. These simulations include the dropsonde profiles in the LES input files, so the LES is being nudged towards the observed state. | + | Currently simulations are focusing on Research Flight 4 which took place on December 14th, 2013, the main reason for this is due to the presence of an elevated moisture layer during the flight.

To accompany the measurements we configured and conducted Lagrangian LES experiments on a selection of days. Each trajectory intersects with one of the mesoscale circles. Some first (preliminary) results are posted below. | To accompany the measurements we configured and conducted Lagrangian LES experiments on a selection of days.

+ | ===== MOSAiC ===== | ||
+ | |||
+ | The MOSAiC (**M**ultidisciplinary drifting **O**bservatory for the **S**tudy of **A**rct**i**c **C**limate) campaign took place from September 2019 to October 2020 during which the RV Polarstern spent a total of 10 Month frozen solid in the Arctic sea-ice. It acted as a base camp for multidisciplinary research of hundreds of scientists from over 20 nations. | ||
+ | The ambitious goal of the campaign is to advance the understanding of the Arctic climate system with a special focus on the impact of global climate change. | ||
+ | |||
+ | As part of the (AC)$^3$ Project, we conduct and analyze Large Eddy Simulations in close connection with observational data. This combination enables us to verify and constrain our simulations using an unprecedented amount of experimental datasets and simultaneously further the understanding of a dynamic Arctic atmosphere. | ||
