Abstract To overcome the lack of the surface micrometeorological data needed for air quality modelling in the Mexico City Metropolitan Area (MCMA), a long-term micrometeorological campaign was carried during the year 2001. Three surface stations were installed at sites found at NNW, NE, and S of the MCMA, each one equipped with a 3D ultrasonic anemometer and conventional meteorological sensors for temperature, relative humidity, pressure, global radiation, net radiation, and rainfall. One-hour averages were calculated for all measurements and for the estimates of the turbulence parameters such as friction velocity, scale temperature, Monin-Obukhov length, sensible heat flux and turbulent kinetic energy, amon
