Supplement of
A climatology of dust emission events from northern Africa using long-term surface observations
S. M. Cowie et al.
Correspondence to:S. M. Cowie ([email protected])
Figure S1. Bar plots of the number of observations at each SYNOP hour, for the periods 1985-1990 (purple), 1990-1995 (red), 1995-2000 (blue), 2000-2005 (green), 2005-2010 (black) for each of the 70 stations.
Figure S2. Mean seasonal cycle comparison using six hourly (right plots) and three hourly (left plots) observations for 18 stations which have stable three hourly reporting. Monthly frequency of FDE, split into BDF (green bars) and DSF (red bars), as well as SWF (blue line), DUP mean (solid purple) and DUP Intensity (DUP mean/SWF, dashed purple, maximum values given), all computed using the seasonally varying T50 (for definitions of parameters, see Sect. 2.2.1, main paper). Thin vertical black lines indicate seasonal boundaries where thresholds change. Note the different vertical axes for DUP intensity.

Figure S3. Annual time series of all observations (black line) and dust observations only (blue line; top plot). Seasonal time series of all observations (middle plot) where DJF=winter(black), MAM=spring(blue), JJA=summer(green), SON=(autumn). The bottom panel is the same as the middle, but for dust observations only.
Figure S4. Mean seasonal cycle of frequency of dust emission (FDE) and strong wind frequency (SWF) for each of the 70 stations. Monthly mean FDE is split into BDF (green bars) and DSF (red bars) (for definitions, see main paper section 2.1.1), as well as monthly mean NDVI (blue lines) calculated for a 24km×24km box centred on each station. Strong wind frequency (SWF; black dotted line) is calculated for winds over T50 (see main paper, section 2.2.1) at each station.
