After two big 3000g-balloons on the last days, the balloons launched today were again 500g-balloons. In addition, a balloon was also launched from El Calafate. Today&#8217;s balloon launches were the last ones for the SouthTRAC Campaign. The altitude record was reached by the 3000g balloon\u00a0from RGA yesterday (Sunday) : 39.47 km. Launching balloons was great fun and lots of valuable data were collected.<\/p>\n<figure id=\"attachment_845\" aria-describedby=\"caption-attachment-845\" style=\"width: 968px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-845 size-full\" src=\"https:\/\/www.pa.op.dlr.de\/southtrac\/wp-content\/uploads\/sites\/6\/2019\/09\/radiosonde_halo_0.jpg\" alt=\"\" width=\"968\" height=\"576\" srcset=\"https:\/\/www.pa.op.dlr.de\/southtrac\/wp-content\/uploads\/sites\/6\/2019\/09\/radiosonde_halo_0.jpg 968w, https:\/\/www.pa.op.dlr.de\/southtrac\/wp-content\/uploads\/sites\/6\/2019\/09\/radiosonde_halo_0-300x179.jpg 300w, https:\/\/www.pa.op.dlr.de\/southtrac\/wp-content\/uploads\/sites\/6\/2019\/09\/radiosonde_halo_0-768x457.jpg 768w\" sizes=\"auto, (max-width: 968px) 100vw, 968px\" \/><figcaption id=\"caption-attachment-845\" class=\"wp-caption-text\">The two airborne measurement plattforms at Rio Grande Airport during SouthTRAC: HALO and balloons.
