# AWTS II

This facility consists of an (approximately 40 m3) environmental chamber housing a recirculating wind tunnel. Key physical parameters can be recreated such as temperaturepressure (from 1 bar to 0.3mbar), gas compositionwind flow and importantly the suspension/transport of dust or sand particulates.

This facility utilizes a network based control and data logging system.

It employs a sophisticated 2 dimensional laser Doppler velocimeter for the quantifying and studying aerosol particles and flow.

New capabilities developed under Europlanet H2020 RI are;

1. An independent air cooling system (for atmospheric temperature control)
2. A high speed imaging system and PIV capabilities
3. A UV solar simulator for aerosol exposure and other experiments.
