In late 2019, the German High Altitude and Long Range Research Aircraft \u201cHALO<\/a>\u201d is relocated to Tierra del Fuego (R\u00edo Grande) at the southern tip of South America, in order to perform atmospheric measurements of meteorological quantities and trace gases at southern hemispheric mid- and high-latitudes.<\/p>\n

The aircraft is equipped with a set of 13 instruments which allow to study the atmospheric state, composition and dynamical parameters by in-situ sampling and down-, up- and sideways-pointing remote sensing.<\/p>\n

The extensive aircraft campaign is conducted in two phases taking place in September and November 2019, respectively, covering the late winter and spring season. HALO returns to Germany between both phases. The four transfer flights between Europe and South America are used to study interhemispheric differences and exchange.<\/p>\n

The HALO measurements are accompanied by ground-based measurements (e.g., lidar, radar, radiosondes) and measurements onboard a glider operating from El Calafate<\/a>. Meteorological and chemical forecast models provide information about local weather, atmospheric circulation, and trace gas distributions necessary for precise flight planning. These activities include contributions from local groups in South America, USA, and other European institutions outside the HALO community.<\/p>\n","protected":false},"excerpt":{"rendered":"
