 I'm very happy on behalf of the organization committee to welcome Professor Filippo Giorgi, who is the head of the Earth Science Physics here in the ICTP and who supports that school and his wishes to tell us a little welcome message. Your floor is yours. Thanks very much. Sorry I'm a bit late. I thought the school was down in the other building. Anyways, welcome to everyone. I guess some of you have been here before and maybe have not. So let me say a few words about the ICTP. The ICTP main mission, at least one of the main missions is to foster research in developing countries. We've had activities in air pollution, in aerosols, especially interactions with climate for quite a number of years. Unfortunately, the person who was leading this activity has left. So we have a job opening in case you are interested. There is a job opening in this area of research. It just came out last week. So in case you are interested, you can apply. And I just want to welcome everybody and my good friend Francois and Eric that I just met today. I hope you have a good workshop. I will be in and out because usually there are many things to do. But if you have any questions or you would like to talk to me, just send me an email and my office is next door in another building. But work in distance. So I'm there in case you want to talk. Well, thank you very much. So thank you, professor. On behalf of the Organization Committee, I just want to thank you again for your support on this school and to thank the staff of the ICTP who made a tremendous work on making that school possible. So thank you to all. Now it's my turn to welcome you on behalf of the Scientific Steering Committee. And before I do so, I'd like to call them so that they can introduce themselves. Starting by Francois, since you're the closest, can you come and say a few words of presentation so that people know who you are? Yeah. Hello, everybody. Thanks for being here. My name is Francois Doulak. I am working at the French Atomic Energy Commission in a laboratory who is dealing with environmental and climate sciences. I've been coordinating a program since 2010 called Charmex, which is the chemistry, aerosol, Mediterranean experiment. So we've been doing a lot of studies on atmospheric chemistry in the Mediterranean region. You can find a number of paper, by the way, more than 60 now in a special issue in ACP and AMT, online journals of Copernicus. And in this program, we decided a few years ago to enlarge our focus and consider the interactions between atmospheric chemistry and its impact on airs. So this is the idea of organizing this spring school, enlarging our communities and our focus, making people meeting themselves between the atmospheric chemistry community and the health sciences. So welcome, everybody. We have people assisting, participating from 27 countries, which is very nice and which is also due to the fact that we are co-funded by ICTP to support people from a number of countries to attend. So it's our pleasure to welcome you here. And please don't hesitate if you have any question on this school. Thank you. Now I welcome Carla Ancona, who's going to also say a few words of welcome. Thank you, Eric. Thank you, Francois. My name is Carla Ancona. I'm Italian, come from Rome in Italy, and I'm an environmental epidemiologist. So my job is to evaluate the health impact of environmental stressors, mainly air pollution, climate change, but also many several others that we all have. I just want to say also myself, thank you very much to ICTP and for the organization, for detecting our assistance for everybody. I'm sure that the way we are now five days together, we can meet each other and we could create a network of researchers. We are 27 countries, but also a very nice mix between people coming from the exposure assessment part, people from the health impact assessment. I think it would be really nice to create a network among us just to point the base for future collaboration. So welcome to the school and I enjoy yourself. Thank you Carla. So we have another person who is at committee with Constantinus Macris, also an epidemiologist in Limassol Cyprus. He will join us later today, so you have the opportunity to meet a little later. And now myself, Eric Amonou, has already told you. I am project manager for Charmets, which Francois told you about, so atmospheric chemistry and impact focused in the Mediterranean basin. And I'm also the animator or project manager for Archimedes, which is a network of scientists, climatologists, atmospheric chemists, and epidemiologists that gather together in order to, like Carla just said, try to create some events, some research projects, some things we could share like this school we are in today. So on behalf of the Archimedes network, on behalf of the participants to this Charmets project, on behalf of the organization committee and the ICTP staff, I welcome myself too to this school on human health and its environmental drivers, climate change, and air quality. And now I just wanted to tell you also that I am very pleased to see you here. And I wanted to congratulate you also for being here since there have been about 120 applications for that school. We could only take 40 to 50 of you. So we decided that we would create a webinar out of this school. So that means that we are filming all the lectures that you will be given here and broadcasting live this lecture onto the internet. So while I'm talking to you 50% here in the room, there are about 50% more registered and watching us online on the internet. So I would like to welcome also this participant, online participant to this webinar. I hope you'll enjoy the webinar. You will have the opportunity to ask questions. We have here our webinar manager You're talking to me now, sorry. Hi guys, hi people in the room and hi people in the webinar. So everybody wants to, I mean all the people in the room will be able to ask questions, of course, directly, but people who want to ask questions from Cameroon, Italy, France, or anywhere in the world who are attending the webinar, of course you can and I will do my best just to transfer these questions to the panelists and we'll come and expose us so interesting things. Thank you. Thank you already. So now I would like to talk a little about why we're here, why we've organized that school and what are the objectives of that school. So Carla mentioned it and this is very interesting. It's exactly what it is meant to be. This school, we all believe that there is a joint need for action to be undertaken for better environment, better human health. And this action needs science to get involved and get connected to some other stakeholders such like the civil society, the economic world or the political world. Science has a great opportunity to act for the diagnostic of the problems to help create, identify the solution, tailor the solution, and maybe also monitor the performance of the solutions. So this, we think that there is a need for more diagnostic and especially when it comes to health impact assessment of climate change and their quality. There are places around the world where we miss those kinds of assessment or where this assessment are rare. So we decided we should gather people together that are all interested in this diagnostic and share with them the theoretical concepts, the methodology, the protocols and the tools so that they could go back to their country and start building their own health impact assessment, sharing the diagnostic together in order to get action on a better air, better climate and better human health for the world. So please, it's all about discussing, questioning and taking all you can back to your countries so that we can make this school successful. Don't leave this place with any unanswered question and make this school a success. Okay, now I have some practical information I want to share with you. We have last minute modification of the program. So there is a switch. It was a talk by Bernard Swingdo at 2.30 this afternoon and a talk at noon by Caroline Cona this morning. So these two talks are switched. Okay, so we'll have Bernard Swingdo at noon and Caroline Cona at 2.30. There are also two poster sessions. One tonight, starting tonight at 4.50 and one tomorrow at the same time. So you've seen that the poster site is around the room in the lobby of this building. Suzanne told us that we should better install the poster on the left hand side of the building here. And please make sure to do so as soon as possible like this we can discuss on your poster during coffee breaks and of course during the poster session tonight. Okay, now we have also some, so we have a build a program that we hope you'll enjoy in this school but we also have worked on the side if some side events. So yeah, there's two side events I want to stress here and invite you to participate first tonight. There is a reception dinner at the Leonardo Adriatico, sorry, building near the seashore down the hill. So it's five minute walk. We can go with a short shuttle at six tonight but if you come back you'll have to come back walking. There is no shuttle to come back this afternoon but it's a very nice walk I can tell you. So you're invited of course, we can share ideas, projects, whatever you want and dinner together on a nice place in front of the sea. And we have on Thursday, another event that we care about a lot which is a round table we want to discuss and get discussion with you, open discussion on a question which is how science can bring better hair, better climate and better health to the world. So we think that this is the opportunity to discuss together what are the difficulties we can face, what is the role of science, what are the opportunities, what are the road map of the track to build this better climate, better health, better hair, better health to the world. Okay and this round table will be animated by Dorothy Mouazon who by the way didn't introduce, I didn't introduce but maybe it's not the time to do so. Dorothy is a senior French journalist and she is now focusing on environmental issues and she will be the one animating that round table. Do you want to wish to say a word on that Dorothy? Yes it will be for Thursday evening, Thursday, I mean at four o'clock or 4.30. For one hour and a half we try to, I mean the issue of this round table is really to exchange together. Sorry for the people for the webinar, this one won't be recorded but for five days you're going to talk about scientific questions which is really interesting but for this round table what we would like is really to tackle the societal, sometimes political questions about air quality because it's really interesting to know how to measure the air quality and evaluate the impact of all that but would be really interesting to know in all these countries you're living in what are the problems you can meet and how maybe some other in some other countries manage to face these problems and what the future could be just to help this air to get better, that's all. So I really hope you will come, many people would come and that you will exchange together panelists and participants, that's really important to exchange together. Thank you. Thank you, thank you Dorothy. Okay now almost finished with this welcome talk just to share some practical information. So lunch, probably most of you know but the lunch can, will be taken here in the cafeteria which is just upstairs this building. You can also have lunch at the Artico building, your ticket, milk cupboards works on both restaurants, both cafeterias. There was an issue Suzanne told me about if you need to get to pay for accommodation or whatever or be reimbursed for anything, it has to be done today otherwise it would be a bank transfer that you need to organize with ICTP. Then we have also this issue of if you have pocket money for daily expenses, this is a two way process, you have to go to a building which is next to this building behind this building and get the check and then get the cash out of the check. This is if you need more information about that you should contact Suzanne. And finally Suzanne stressed that we have here some historical things to see. So the library is very interesting and there is the office of Abdul Salam who researcher who was the one who was a famous researcher in particle physics and who gave his name to this institution. Well, so I also added two contact person, key person, Suzanne Inningson for any issue related to ICTP. Okay, you have her email. And for program related questions if you need to contact somebody if you want any question on the fact if the slide will be available or whatever, you contact me. So I'm through, I wish to, we're gonna move to the first lecture by Joss Lelyveld who is a specialist in atmospheric chemistry, a specialist also in climate change and impacts of atmospheric chemistry and climate impact. And who is working at the Max Planck Institute, great contributor on both, on all those fields. And I will now declare the school open and enjoy.
