A lattice gas simulation approach to the wind field diagnostic problem in two dimensions is proposed. This approach is based on a square lattice gas model with interactions up to second nearest neighbors that conserve the number of particles, momentum and kinetic energy. It was applied to the case of the Mexico City Metropolitan Area using wind velocity data from a four sites micrometeorological campaign carried out in Mexico city during the 1994 summertime. Computer simulations for daytime and nighttime hours were performed and the results were found in a good agreement with the wind data registered by the meteorological stations of the atmospheric monitoring network of Mexico City.
