|Description of the infrastructure|
|Brief general description of the infrastructure to which access is offered||
The Roland von Glasow Air-Sea-Ice Chamber (RvG-ASIC) facility at the University of East Anglia (UEA) comprises a coupled atmosphere–ocean–sea-ice simulation chamber designed to investigate the role of first-year sea-ice in tropospheric chemistry. The temperature of the chamber can be controlled within the range –55 to +30 °C, with a stability of ±0.3 °C.
|Services currently offered by the infrastructure and its research environment||
Full access to the RvG-ASIC, including:
|Modalities of access and support offered under EUROCHAMP-2020|
|Typical duration of work||
10 days per experiment, including 3 days for set up and ice-growth, 5 days experiment and 2 days clean-up / packing up / data distribution. Variations may occur, depending on starting conditions required and how much ice is required to be grown.
|Community/user type served||
RvG-ASIC is mainly used for academic research, but there are opportunities for industrial users / SMEs for sensor and other equipment testing in a variety of extreme polar and ocean simulated conditions, e.g. In / under ice, cold seawater or freshwater, cold atmospheric conditions, under natural lighting conditions or enhanced UV conditions.
|Scientific and technical support offered||Training for the general use of the facility along with data processing will be provided as needed. Advice on set up / experimental conditions will be offered if requested. Technical and scientific assistance by affiliated researchers within UEA. Data storage and access to data remotely post experiment.|
|Logistic and administrative support offered||Administrative support for ordering chemicals and consumables, logistic support for the management of chemicals. Guest office space. Help with accommodation (available on campus or nearby).|
