In Antarctica, the assessment on a continental scale of radiation budget and related parameters is challenging due to the limited number of observation stations, and even more so when funding methods and the complexity of coordinating different research groups and activities are considered. All this has hindered concrete actions toward the creation of a regional network and its absence has inhibited the dissemination of the methods developed and implemented by the Baseline Surface Radiation Network (BSRN). The resulting lack of harmonisation/heterogeneity of measurements gives rise to an intrinsic weakness that can be overcome by establishing a network within the community.
To this end we have started to plan an initiative aimed at building a regional network for radiation in Antarctica.
The first step is to discuss in a workshop all the aspects connected to such objective, such as:
- radiation budget and its components,
- UV radiation (and columnar ozone from ground measurements),
- albedo/surface reflectance,
- clouds/cloud cover.
- any issues related to ongoing observations (where, which instruments, responsibility, long-term plan, instrumental challenges, methodologies, etc...),
- actions to establish a regional network (including the connection to BSRN),
- ways surface observations can provide information to climate models or help with assessing (through suitable indicators) climate state and trends.
The workshop will be held online, from 5 July to 7 July 2023 on Zoom, the link will be sent close to the meeting. Everyday there will be a single session at a time convenient to ensure a participation as broad as possible given the different time zones of attendees.
In addition to the virtual workshop, a hybrid side-event will be held 18 July 2023 at the IUGG23 in Berlin to keep the momentum going and strengthen the connection of ARRN initiative with the AntClimNow community. Online workshop agenda The three sessions will allow to address: July 5, 2023.
