I am looking into squalls off Mauritania.

I can get current hourly wind data from Ihle de Sal in the Cape Verde
Islands from:
http://weather.noaa.gov/weather/current/GVAC.html

and can get the 3 or 6 hourly data from 1994 to present from the GTS
from Nouakchott, Dakar and the Cape Verde..

But I need to get reliable hourly, 10minute mean and gust information
from Ihle de Sal and Dakar, especially during squalls.

I'd appreciate any information.
