 The international EUREC4A campaign took place in February-March 2020 in the Caribbean, in an area east of Barbados. One of the main goals is to probe the subtropical marine Trade wind boundary layer with state-of-the-art instrumentation, including fast-flying high-altitude aircraft (HALO) and slower low-altitude aircraft (the ATR), research vessels, sensors at the BCO site at Barbados, and satellite images. A particular meteorological focus is on detecting and understanding mesoscale cloud patterns. Part of this is an effort to reliably estimate the large-scale conditions in which these patterns form, including subsidence, pressure gradients, and advection. To this purpose, HALO flew mesoscale circles.
 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.

 ===== 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.
