To provide data and information we looked for different meteorological station, the first one of the Mexico City (Tacubaya Meteorological Observatory) and the second one in Texcoco (DGE-MX meteorological station), the distance between the two points is around 40 Km and the Texoco’s altitude is 2.257 m. Probably to understand with more detail the UHI effect in Mexico City will be good to choose another meteorological station in the rural area. These information could be a starting point for the analysis. ![][1] The analysis methodology to understand the UHI in the Mexico City have three steps to transform data in information and information in knowledge: - Collection data of different meteorological stations (Mexico City and Texcoco) - Meteorological data analysis of the two stations - Compare meteorological data The data and information for the two meteorological station had been find in different web site, the Mexico City’s data was in http://www.tutiempo.net/ with historical register since 1973 to today, and the Texoco’s information in http://clicom-mex.cicese.mx/ with data for Texcoco since 1978 to 2012. How we haven’t data for Texcoco for the last three years we only analysis the information data since 2006 to 2012. The information of the two meteorological station provide daily information with average temperature, maximum and minimum temperature register. The compared information provide data regarding the difference of climate behavior in the two points. ![][2] The result obtained of the data and information give us an idea of the UHI effect in Mexico City, the most important result after the analysis were: - The hot period in Mexico City is between May to September - 1.200 days with average temperature higher in Mexico City (2006-2012) - 858 days with average temperature higher around 2.5°C in Mexico City (2006-2012) - 269 in the hot period of Mexico City with average temperature higher in 3.6 °C than Texcoco (near to 7 days per moth) - 1.563 days with minimum temperatures higher in Mexico City than Texcoco. Probably the UHI effect in Mexico City induce two situation: - Increase the maximum temperatures over day - The UHI effect doesn’t allow cooling at night. Compare the two images in terms of reasons that contribute to the UHI effect of the city ![Mexico City][3] Mexico City ![Texcoco][4] Texcoco Mexico City with an extension of 8.000 Km2 (approx.) has more than 2o millions of inhabitants have a high challenges to reduce the UHI effect, the critical points in compare to Texcoco are the next: - Rate of urbanization, higher in Mexico City that Texcoco - The inertial mass of the building material in the city is higher in Mexico City (more urbanization) - Green zone are not sufficient in Mexico City - The heat generated by industries and buildings activities (associate with GHG emissions) - The heat generated by private transport - The location of Mexico City (in a Valley) increase the effects of UHI Probably the effects of UHI in Mexico City could be similar than a greenhouse effect in a local scale. To reduce the UHI effect in Mexico City and provide more livable environment to the citizens the first option will be a Strategic Plan for Livability in the City, the first steps to reduce the UHI effect could be: - New criteria for private vehicles more demanding in the GHG emissions - Rehabilitation of the neighborhoods with more green zones, sustainable buildings materials with more sustainable criteria en the design phase - Master Plan to relocate the industrial business out of the City In the 70s years the Mexico City’s Governments started with a plan of deindustrialization of the City. Some years ago the Government of the Mexico City had been promoting the prohibition to circulate the older private’s vehicles (this measure doesn’t include freight vehicles) and in the last year this measure stop being applied.
