March 11:
The LAMDA-S team is finally complete! We met up with Lino and Gonzalo, who work at the VAG station field site. Today was the first day that the whole team could access the station, which is located inside Ushuaia Airport.
We took the first measurements to study the buoyancy of the MPI-DS balloons so that they can follow the local flow. The gel that we made at home worked pretty well! These balloons should stabilise at a target altitude, enabling us to study transport phenomena.
The test was successful, and it was a great first day at the site.

High chances of catching an atmospheric river (AR)!! Our star forecast team, Alejandro and Denise, gave us a briefing on when to expect the (possible) AR. Its tail should reach Ushuaia on Sunday 15th. Fingers crossed!

Being able to improvise is a key part of being a scientist 😉! After the loss of an anti-leakage gel due to airline regulations, we decided to make our own gel, just after our arrival. Florencia Z and Eberhard spent some time on getting the right “recipe”. We will test the MPI-DS gel in the upcoming days.

The LAMDA-S team has landed in Ushuaia. Tomorrow, we will get the necessary permits to work at the VAG station at the airport. In the meantime, we will start preparing everything: from living arrangements (such as grocery shopping) to pre-campaign preparations.
March, 06: Buenos Aires
This week, the LAMDA-S team met at the SMN to discuss strategies for the upcoming field campaign. All team members gave talks at the two-day joint MPI-SMN-FLiP-IFINA seminar. As well as hearing talks from the three institutions, tours were given of the SMN's and FLiP-IFINA's facilities. The discussions were very fruitful, strengthening the collaborations between scientists and institutions.
March, 01: Arrival in Buenos Aires
February, 28: Flight of the Göttingen team from Frankfurt, Germany to Buenos Aires, Argentina
February, 26: With the arrival of the German side of the LAMDA-S team in Buenos Aires, a joint seminar series will be held at the National Weather Service of Argentina on 4 and 5 March. Contributions will come from the MPI-DS, the SMN, and the FLiP-INFINA-FCEyN group at the University of Buenos Aires. Topics covered will include the objectives and context of LAMDA-S, atmospheric turbulence and atmospheric rivers, current field experiments of the MPI-DS, as well as ongoing experimental, numerical, and observational research activities carried out by the FLiP group. The full schedule can be found here.
February, 25: Only three more days until the departure to Ushuaia. The team from Göttingen is getting ready and finalizing the preparations.
