Portable and affordable environmental sensors are becoming popular in Citizen Science activities and are also gaining ground in scientific projects. The recent publication of the WMO report on “Low-cost sensors for the measurement of atmospheric composition: overview of topic and future applications” has signalled the importance of Low Cost Air Quality Sensors (LCAQS) as well as the high interest of the scientific community, city authorities and citizens to their development and application. Such sensor technologies can provide comprehensive information concerning a wide range of pollutants with high spatial and temporal resolution, providing valuable insight concerning the understanding and dynamics of urban air quality as well as of indoor air. Furthermore, low cost sensors can also provide information about acute environmental pollution allowing fast identification of sources and threats. On the other hand, their limited accuracy and their lack of performance when compared to reference instruments pose considerable challenges toward their improvement to achieve acceptance in various application fields.


The school aims at providing fundamental training and expertise in the area of urban air quality monitoring and modelling, for better and more effective LCAQS design, development, calibration and use. LCAQS technologies and basic functionalities will also be addressed. The training school will address the technology chain from sensor elements via sensor systems and calibration to their use for environmental services incl. combination with modelling.


Expected results


The main result will be the knowledge shared and the collaboration potential that will be increased between the training school participants. Students will

  • receive MSc/PhD level education from University Professors/researchers that have a high experience in urban air quality modelling and monitoring and in LCAQS characteristics and use
  • work in the interdisciplinary domain of LCAQS use, approaching them not only as open source hardware but also as IoT nodes for smart city applications


Date  and duration


Week 36: September 2, 2019 @ 09:00 – September 6, 2019 @ 13:00. Duration of 5 days.




Aristotle University, Department of Mechanical Engineering, Thessaloniki, Greece (campus map). The training school will take place at the meeting room of the Faculty of Engineering.



The training school is expected to host a total of 20 students from various countries. The average amount of financial support per participant is 700 Euros (travel, accommodation and meals to be covered, according to COST rules) and it is not intended to cover the full cost of the attendees, but it acts as a grant. Emphasis will be put on MSc and PhD students as well as on young researchers. Attendees will be selected based on the relevance of the school to their work, as well as to ensure gender balance and geographic diversity.


The PortASAP Training School involves a separate registration and selection procedure. You are eligible to participate or to receive the financial support grand ONLY if you have received (and accepted) the official invitation through e-COST (see below), to be expected in late July/early August.


Registration costs: The training school has no registration costs (is free of charge). The training school organizers will therefore apply a registration and selection procedure of trainees.


Other costs: Travel, accommodation and insurances and other costs have to be paid by the trainee him/herself. Meals costs are also to be covered by the trainee him/herself (access to Aristotle University’s student restaurant will be arranged).


Contact persons regarding the content of the Training School:

Registration procedure of trainees:

Applications open: May 20th

Applications close: June 24th, 2019

Applicant’s notification of acceptance: July 1st, 2019

Each applicant has to register in e-COST adding his/her bank details to his/her e-COST profile and and apply via a google form ( providing personal info plus the following documents (in addition to filling-in the registration form, the documents should be sent via email to thess(at)


  1. A motivation letter briefly (max 2 pages) introducing the applicant, interest in low cost AQ sensors and air pollution management, participation in relevant projects/research activities, previous involvement in PortASAP activities, motivation and benefits for Training School participation especially in relation to own studies and career goals, possibility to disseminate Training School topics through education or awareness sessions within their own institute or countries. Applicants should also include a title of the poster that they will present, which can discuss their current research activities.

Selection procedure of trainees:

Announcement of the selected trainees and their reimbursement: 15th of July 2019

Official invitation by e-COST to participate in the Training School: 30th of July 2019


The training school applications will be considered by a committee chaired jointly by the event organizer (Prof. K. Karatzas), the Chair of the Action (Dr G. Erny) and three CORE or MC members. The outcome of the evaluation will be notified by the event organizers. Thereafter the trainees will be officially invited to participate by a message sent by e-COST.

Only applicants who have registered in e-COST, including their bank details and who have submitted their CV and cover letter will be permitted to take part in the selection procedure.
