The DACAPO-PESO deployment of LACROS is about to become serious. A one-person advance party already arrived at Punta Arenas last weekend. During the week, some logistics had to be prepared and coordinated with our colleagues of UMAG and  some local companies.

On Friday, the 23 November, the two containers with the instruments finally arrived at UMAG, Punta Arenas. Two trucks, a crane and several slingers were at the site before 7 o’clock in the morning. Together with staff from TROPOS and UMAG, locating the containers on the prepared concrete bedplates went smoothly.

Following the first impression, the containers seemed to have survived the 2-month sea transport rather well. As a last task for this day, the electricity connection was installed and the air conditioning/heating was powered up.

The instruments will be set up and put to operation during next week, as soon as two more scientists from TROPOS arrive here. Let’s hope that nothing (too serious) broke during transport.

After busy weeks of maintenance work and packing, both LACROS containers were picked up at TROPOS today. Next stop is the container terminal of Hamburg. The containers are scheduled to continue their journey from Hamburg to the harbor of San Antonia, Chile, on 21 September. The container ship will likely be MSC Antonella (more information about the ship here).
At San Antonio harbor, it is planned to put the containers on the container ship CONDOR (more information about the ship here). Let’s keep fingers crossed that everything will work fine and within the schedule.

During the first week of May, a second preparatory meeting took place at UMAG, Punta Arenas. This time a three-person team from TROPOS (Cristofer, Zhenping, Martin) came to Punta Arenas to advance the preparation of DACAPO-PESO.

A one-day workshop together with representatives from UMAG and Dirección Meteorológica de Chile (Chilean Meteorological Service) was the most important appointment during the week. Well organized by our collaborator at UMAG, Boris Barja, several talks were given on current research topics and opportunities for further collaboration. After the presentations plenty of time remained for discussions and networking.

The remaining days were filled with various tasks. Scouting a potential field site for undisturbed aerosol sampling meant hiking up Cerro Mirador – a 600 m hill hosting several telecommunication ground stations and Punta Arenas’ skiing resort. During late autumn with temperatures slightly above freezing and winds around 40 kt this trip was a little bit demanding, but most likely there will be the opportunity for in-situ sampling during DACAPO-PESO.

We also visited the local office of the DMC at the airport of Punta Arenas and discussed joint measurements and the exchange of data. From this office, the DMC monitors the surface observation network in the Magallanes region, launches radiosondes daily and issues the aviation weather reports. Furthermore, a short meeting was held with a logistics company regarding the final delivery of the LACROS containers at Punta Arenas.

After a quite successful week, the return trip did not start at the airport, but at the port, where we boarded the German research vessel Polarstern. During the four-week cruise back to Bremerhaven, Germany we took care of the OCEANET container.
