Air quality: ¿What is a compass rose and a pollution rose?.

A Compass Rose is a graphical database that summarizes the Vectorial behavior of the wind in a place. It has three main components: direction, intensity and frequency.

The information of each Compass Rose shows the frequency of occurrence of the winds in 16 sectors of direction (E, ENE, NE, NNE, W, WNW, NW, NNW, ESE, SE, SSE, S, SSW, N, WSW , SW) and types of wind speed for a specific place and periods of time, the classification most used for wind is the BEAUFORT SCALE.

A Compass Rose is made just like a frequency table, one category is the address and its subcategories are the 16 directions, the other one category is the speed and the different types of wind considered by Beaufort as the subcategories.

A Pollution Rose is a graphic database, which indicates the direction of the emission sources that influence any station. It has three main components: speed, direction and concentration levels.

For this example, the Pollution Rose indicates that the main emission source is local (low speeds) and it comes mainly from the Southwest (SW).

The Polar Circumference is a graphical database, which represents in the wind direction the concentrations reached in function of the hours of the day.

In this way, it is possible to see at what times of the day the highest concentrations have occurred and in which wind direction have occurred most.

For this example, the Polar Circumference for the period of analysis, indicate that the highest concentrations come from the northeast (NE), east-northeast (ENE) and east (E) and occur after 07:00 hours.


K2 INGENIERÍA participates in the Sustainable Aeronautics Forum, organized by the Rosario’s University and the SKBO Social Committee.

The Rosario University of Bogotá hosted the Sustainable Aeronautics Forum 2017, coordinated by K2 INGENIERÍA and the SKBO Social Committee, a group made up of different companies of the Colombian Aeronautical Sector.

(SKBO is the ICAO code for the El Dorado airport, and is used as a summary form to talk about the Airport Terminal of the Capital of Colombia)

For 4 years, the SKBO Social Committee, which includes several companies in the Aeronautical Sector of Colombia, promotes technical meetings aimed at sharing, disseminating and stimulating sustainable actions in airlines and Colombian airports. Since its inception, K2 INGENIERÍA has been part of the Committee.

The Sustainable Aeronautics Forum is an academic meeting with the support of the Psychology Program of the Rosario University of Bogotá and its Organizational area. Featured exponents represented companies and entities committed to the environment, the business economy, communities and society.

The selection of exhibitors was first class, headed by the representative of the Colombian Aeronautical Authority and the Aeronautical Studies Center ASC, Sergio ParÍs, who presented the actions of the Entity manifested in spaces such as the Green Airports Meetings, which in 2018 will reach the third version. Tania Chacín, Opaín HSEQ Director, concessionaire of the El Dorado Airport, presented the page “The green side of El Dorado” and presented several sustainable actions of the main airport in the country. Opaín has been one of the regular participants of the Green Airport Meetings since its inception.

The AirPlan concessionaire, who has also been frequently present at the Green Airports meetings, highlighted the actions at the Caraño Airport in Quibdó, presenting the sustainability plan and the first steps for sustainable buildings in this terminal, exposed by Engineer Jhon Jairo Ortíz and Engineer Yesenia Loaiza.

LATAM Airlines has also been a committed and regular participant, has been present since its inception in the SKBO Social Committee and in the Green Airports Meetings. Maria Lara, director of corporate affairs LATAM Airlines Colombia, who presented the Climate Change Management Strategy, spoke on behalf of this outstanding airline.

Avianca was represented by John Karakatsianis, Director of Corporate Citizenship Avianca Holdings. The airline exposed its sustainable social strategy, presenting a novel model of interaction and social action.


Leonardo Amaya intervened for K2 INGENIERÍA, presenting the theoretical model that supports the sustainable social design of the Environmental Monitoring and Quality System of Aerocivil for El Dorado Airport. Aerocivil’s commitment to sustainability allowed the application that K2 INGENIERÍA as a consultant proposed and designed, always with the strong support of the Aeronautical Authority. Leonardo Amaya is Social Director of the Environmental Quality and Surveillance System and professor of the Psychology Program of the Rosario University, host of the Event.
