Site DescriptionIn addition to the prevailing weather conditions being recorded at the 30m mast at Cwm Level Park, there is a requirement to understand the complex turbulence within a typical street canyon. The 9m mast fixed to the front of the Hafod Post Office will allow collection of wind direction and speed data at 5m above the roof ridge level (responsible for introduction of background pollution) as well as both horizontal and vertical wind speeds within the street canyon itself. These measurements will have a resolution of 1 minute and will aid the definition of the vertices and mixing capacity of the street canyon. The data will be used to determine and evaluate the atmospheric chemistry responsible for the formation of NO2 (and O3) within the street. In addition, these data will also be used to aid the validation of the predictive output from Nowcaster.
All data is sent by radio modem every second from the mast to the receiving station for the Hafod Opsis DOAS where the data is logged and integrated into 1 minute data and sent by FTP transfer to our FTP server.
