These lidar data show the passage of smoke from forest fires in Canada over the lidar site at Capel Dewi near Aberystwyth in Wales. A description of the event is provided in Vaughan et al, Atmos. Chem. Phys., DOI: 10.5194/acp-2017-1181. The files contain the photon-counting signals from the lidar as count-rate*height in km squared (corrected for background and pulse pileup), statistical errors in those signals, and synthetic molecular atmosphere profiles derived from two representative radiosonde stations in the vicinity. The counts have been integrated in time over a night, as follows:
May23: 2148 on 23 May to 0309 on 24 May
May24: 2126 on 24 May to 2206 on 24 May
May26: 2304 on 26 May to 2344 on 26 May
May29: 2111 on 29 May to 0331 on 30 May
May30: 0036 on 31 May to 0257 on 31 May
Cloud prevented night-long observations on these nights - cloud-free profiles were selected and combined by visual examination of the raw data.
