Measurements of Saharan dust deposition. A simple sampling technique : the pyramidal collecting system
The collecting system is presented. It is a simple pyramidal receptacle which records
Saharan dust deposition at regional scales on a daily basis. Where as the common air-filter sampling
system is usually filled-up due to very high aerosol concentrations, our system is proved to be efficient
whatever the conditions. The annual thickness of Saharan dust layer over the whole Cape Verde area
is estimated at 70 p. y-'
