goSouth-2 and partner activities
The below map illustrates the locations and projects which are associated to goSouth-2. While the main site is located at the premises of MetService in Invercargill, associated measurements have been conducted at the Tāwhaki Aerospace Center just south of Christchurch. Furthermore, the independent aircraft experiment HALO-South and the shipborne field experiment ACAROA are strongly related to goSouth-2.
1) goSouth-2 main site: LACROS at Invercargill
The main site of the goSouth-2 experiment is located on the premises of MetService New Zealand in Invercargill.
The coordinates are as follows:
- 46.4173 °S
- 168.3307 °E
- 5 m asl
The site hosts instrumentation of Leibniz Institute for Tropospheric Research (TROPOS). Most of them belong to the Leipzig Aerosol and Cloud Remote Observations System LACROS, which has been extended by additional in-situ instrumentation. Furthermore MetService provides atmospheric soundings, surface meteorological observations and precipitation radar measurements. See <<Link to instruments>> for an overview of the deployed instrumentation. The duration of the deployment is scheduled to cover the time range from 24 August 2025 until 31 March 2027.
2) the ACADIA partner site of LACROS at Tāwhaki Aerospace Center
An essential project that is related to the goSouth-2 experiment is ACADIA (Aerosol-Cloud Interactions in Aotearoa New Zealand). In the framework of ACADIA, additional remote sensing observations have been performed on the premises of the Tāwhaki Aerospace Center, about 50 km south of Christchurch.
The coordinates are as follows:
- 43.8279 °S
- 172.5378 °E
- 5 m asl
The site of Tāwhaki hosts instrumentation of the Meteorological Institute of the University of Leipzig and the University of Canterbury, Christchurch, NZ. See <<Link to instruments>> for an overview of the deployed instrumentation. See also this <<Blog article>> for a more detailed introduction to the field site.
3) Associated projects HALO-South and ACAROA
The below map shown in addition some core information about the associated projects HALO-South and ACAROA.
- HALO-South was a campaign of the German High-Altitude Long-Range Research Aircraft HALO of the German Aerosospace Center DLR. It was conducted in September and October 2025. The orange circle in the below map indicates the radius of approximate maximum range of the Aircraft. More information about HALO-South can be found at <<Link to HALO-South webpage>>.
- ACAROA (Atmospheric Clouds, Aerosol, and Radiation in the Southern Ocean around Aotearoa) is a proposed activity to deploy remote-sensing and in-situ instrumentation for aerosol and cloud research onboard the German Research Vessel Sonne. ACAROA is still in the decision phase. If funded, it will take place in the first quarter of 2025. The proposed ship track is indicated by the black track in the map below.
