2 NATIONAL SOLIDARITY FUND COMPENSATIONS IN THE PERIOD 1978-2003; In this work we have collected the administrative documentation of the adverse atmospheric events that resulted in compensation for damage, and available information in terms of: their temporal frequency their territorial distribution their risk calendar the average vendible gross production damage at municipal level
