We report the results of a two-dimensional (2-D) simulation of a cylindrically symmetric positive streamer in atmospheric pressure air between a positively stressed point and a grounded plate. A hydrodynamic diffusion drift model was used. It is shown that a streamer propagates with the constant velocity and constant field at the tip (≃140 kV/cm) and constant electron density in the head (≃1014 cm-3). Special attention has been paid to the generation of excited molecules, radicals, and atoms [chemically active species (CAS)] by the streamer, 2-D distributions of CAS are obtained. The total number of CAS linearly increases with time (except excited oxygen molecules) in accordance with the constant velocity of streamer propagation. The mean energy cost of each active specie is 35 eV
