Deposition and Atmospheric Nitrogen Concentrations Trends in Cuba

The NO₂, nitrate and ammonia sampling in aerosols and rainfall was carried out at five stations located along the Cuban Island from 1986 to 1991. The sampling and chemical analysis were made mainly on the basis of methodologies recommended by WMO for above mentioned compounds at regional level. The total deposition of these compounds varies from 0.706 to 3.317 g m^-2 yr^-1. The wet deposition is about of 60%, so that the dry one is 40%. The amount of both depositions depends on our tropical rainy climate features. For some of these compounds the trend is increasing.
