Historically, Madrid’s air[br]has been represented by its skies,

0:00:12.845,0:00:15.513
from Velázquez, who took[br]the entire royal court outdoors

0:00:15.537,0:00:17.514
to paint their portrait,

0:00:17.538,0:00:22.375
to photography nuts who post[br]their Madrid photos on Flickr.

0:00:22.399,0:00:27.175
This is the first image that shows up[br]when you search "Madrid" on Flickr.

0:00:28.173,0:00:32.086
Still, even if this is how[br]the Madrid sky appears

0:00:32.110,0:00:34.825
in our collective imagination,

0:00:34.849,0:00:36.886
on a day-to-day basis,

0:00:36.910,0:00:38.255
Madrid's sky looks like this

0:00:38.279,0:00:39.857
and like this

0:00:39.881,0:00:41.162
and like this.

0:00:41.186,0:00:44.457
And only those photos you see[br]in the newspapers now and then,

0:00:44.481,0:00:47.461
can actually reveal the bad[br]quality of air in Madrid.

0:00:48.638,0:00:49.928
It makes you wonder:

0:00:49.952,0:00:53.459
Why do we know so little[br]about something like air quality?

0:00:53.483,0:00:55.054
And the answer is very simple -

0:00:55.078,0:00:57.497
because it's microscopic[br]and we don't see it.

0:00:57.521,0:01:01.344
Thus, the "In The Air" project was born,

0:01:01.368,0:01:05.273
with the intention of giving[br]legitimacy to a system

0:01:05.297,0:01:06.919
that forms a part of our city;

0:01:06.943,0:01:08.821
a system with which we interact,

0:01:08.845,0:01:10.598
that runs our daily lives,

0:01:10.622,0:01:14.370
and that has a very close[br]relationship with our bodies.

0:01:14.394,0:01:16.956
The project is a collective effort,

0:01:16.980,0:01:21.733
built by a fantastic team[br]of multidisciplinary collaborators

0:01:21.757,0:01:23.838
from all over the world,

0:01:23.862,0:01:27.377
and developed through workshops,

0:01:27.401,0:01:30.924
like Media Lab Prado in 2008,[br]the first of such events.

0:01:32.067,0:01:33.743
But back to the air.

0:01:33.767,0:01:36.632
Allow me to present its actors:

0:01:36.656,0:01:41.409
gases like CO2, nitrogen dioxide,[br]ozone, sulphur dioxide,

0:01:41.433,0:01:46.578
or suspended particulates[br]like rubber, leather, lead...

0:01:49.342,0:01:52.467
Ever since Spain[br]joined the European Union,

0:01:52.491,0:01:57.433
Madrid's city council is obligated[br]to inform the public about air quality.

0:01:57.457,0:01:59.487
This is how they presented it in 2007,

0:01:59.511,0:02:01.494
and like this for 2008, 2010.

0:02:01.518,0:02:03.114
But it makes you wonder:

0:02:03.138,0:02:08.082
Could we find a more adequate[br]way to present the information,

0:02:08.106,0:02:12.101
so we could have a better sense[br]of what's going on with our air?

0:02:12.125,0:02:14.603
We found there were two things missing:

0:02:14.627,0:02:19.918
geolocalization and the order of events.

0:02:19.942,0:02:24.715
So we put together these graphic maps,[br]which are basically air landscapes.

0:02:25.739,0:02:29.463
You can see them in real time[br]on an interactive web page,

0:02:29.487,0:02:31.712
where you can view[br]all the different components

0:02:31.736,0:02:34.045
and navigate the city[br]from below its airstream.

0:02:35.041,0:02:40.122
We can also see what effects[br]our actions have on air quality,

0:02:40.146,0:02:42.489
on both a city scale

0:02:42.513,0:02:44.286
and also per 100,000 inhabitants.

0:02:45.331,0:02:49.266
We can also identify[br]where emissions are coming from,

0:02:49.290,0:02:52.035
and how they might affect our health.

0:02:53.226,0:02:55.459
It's been interesting[br]to read through the data.

0:02:55.483,0:02:59.244
It's allowed us to see[br]that there's a very close relationship

0:02:59.268,0:03:02.509
between what happens in the city,[br]our own everyday actions,

0:03:02.533,0:03:04.576
and what's produced in the air -

0:03:04.600,0:03:06.744
what we produce, collectively, in the air.

0:03:07.140,0:03:10.634
For example, in the spectacular case[br]of a New Year's Eve,

0:03:10.658,0:03:13.557
when the particulate suspension levels[br]dramatically increase.

0:03:13.581,0:03:16.453
The same happens during soccer games[br]in Bernabéu Stadium.

0:03:16.835,0:03:19.622
The project also examines

0:03:19.646,0:03:22.824
how the way in which we transfer[br]this information to public spaces

0:03:22.848,0:03:24.815
can produce different reactions

0:03:24.839,0:03:27.336
as well as differences[br]in the collective dynamics

0:03:27.360,0:03:30.413
involved in plazas and public spaces.

0:03:31.307,0:03:33.294
So we developed several prototypes.

0:03:33.318,0:03:36.625
One of them was this cloud of colored mist

0:03:36.649,0:03:38.353
on the facade of Media Lab Prado

0:03:38.377,0:03:41.792
which represents the levels[br]of air pollution by pulsating.

0:03:41.816,0:03:47.109
This digital facade allows us to identify[br]minimally polluted routes.

0:03:49.094,0:03:52.501
There are also mobile devices[br]that help us navigate the city,

0:03:52.535,0:03:57.287
orienting us like a sort of aerial compass

0:03:58.017,0:04:04.422
while transmitting in real-time,[br]information about the urban surroundings.

0:04:06.700,0:04:09.864
We're currently researching[br]this "public good,"

0:04:09.888,0:04:11.859
as it's been called several times today.

0:04:11.883,0:04:14.549
It's intimately linked with our bodies,

0:04:14.573,0:04:18.776
and since it can impact the health

0:04:18.800,0:04:21.904
of the citizens of Madrid,

0:04:21.928,0:04:25.270
all of our bodies are affected by it,

0:04:26.159,0:04:31.159
and by the processes of exclusion[br]that it will eventually produce.

0:04:33.225,0:04:36.492
We're also looking at what types[br]of visual formats are best,

0:04:36.516,0:04:40.214
and to what extent a visualization[br]can motivate, stimulate

0:04:40.238,0:04:42.831
or act as an intermediary[br]for political action,

0:04:42.855,0:04:45.693
on both an individual[br]and collective level.

0:04:47.830,0:04:50.282
Let's take a look at how Madrid breathes.

0:05:54.496,0:05:55.770
Last inhale.

0:05:56.353,0:05:57.642
Thank you very much.

0:05:58.686,0:06:01.201
