We give a formula expressing the second Chern class c{sub 2}(E) in terms of trivializations of a rank two vector bundle E at scheme points of a surface X over a field. To do this, starting with these trivializations, we construct a cocycle in the adelic complex associated with the sheaf K{sub 2}(O{sub X}). Furthermore we prove that the Severi formula for the second Chern class is obtained as a special case of the formula constructed in this work. Bibliography: 10 titles.
