Presented by Andreas N. Skouloudis (JRC) during the 2nd BDE SC5 workshop, 11 October 2016, in Brussels, Belgium

1. «(Big) Data for
Env. Monitoring, Public Health and Verifiable
Risk Assessments-
New technologies with innovative handling
with data gaps»
1. Five Cases of big handling in the past (1854),
2. State-of-the-art uses,
3. The prospects ahead.

2. Mapping example of near (real)-time process
• Cartography identified the origins of the cholera during the London
Broad Street epidemic in 1854.
• The containment of the epidemic was effective when the water
pump was sealed at the Soho Broad Street.

3. Long-term temporal Hazards

4. Short-term acute events

6. Future needs involve Several Disciplines
(health)

7. 2d AutoOil Programme
1. Select modelling periods for annual mean and episodes;
2. Input data on land use, topography, meteorology (multi-layer), and emissions
(PiG) in order to characterise each modelling domain;
3. Definition of three dimensional wind patterns using meteorological models with
two-way nesting;
4. Calculation of concentrations of different pollutants using full photochemistry;
5. Validation of the modelling results;
6. Adjustment of 1995 emission inventories to 2010;
7. Simulation runs for 2010 and comparison with objectives;
8. Development of emission reduction targets and simplified emission/air quality
relationships (source apportionment);
9. Investigation of alternative emission scenarios (sensitivity tests);
10. Generalisation for all cities in the 10 domains
(1065 towns, or 46% of EU15 urban population or 27% of all EU25 pop).

8. Actual measurements in 2010
BIG Data analysed 91,980,000 hourly records
(2years*365days*24hours*5species*1050geo-locations)

9. Environmental Monitoring …
• Satellite and UAVs for
covered areas:
 High resolution of
affected areas.
 High revisit periods are
essential.
• In-situ climate sensors:
 Real-time datasets
compact (weather)
stations.
 Not rely only on synoptic
observations.

10. Climate advancements
Examples …
1. GISS ModelE2.
2. Ron L. Miller et.al. measurements since 1850 AGU at the
J. of Advances in Modelling Earth Systems.

11. Big data for regulatory applications
• Real-time 10min met data
Examples …
1. Eliminate the use/uncertainity of questionnaires.
2. Harmonize highly heterogeneous data, fill data gaps
and verification of population effects.
3. Deal with questions of society and ethics.
• Personal activity data

12. Population density maps from mob telephones
Francesco Pantisano EUR Report 27361 and
http://opencellid.org

13. … sensors and underwater robots
•…divers collect and sending samples back to the lab to
be tested,
•This FP7 robot makes this process real-time with
chemical sensors that makes these tests in-situ.
•…3000 buoys deployed at seas for conventional data
(GEOSS)

14. … sensors for citizen needs TrackR
• …ideal for practical applications but,
• Essential for real-time security and
vital intervention in emergencies in-
situ (earthquakes).

15. Final remarks Areas and Specific Efforts
• Environmental monitoring per sec has
consequences for proliferation of data and for
pushing research to a new generation of tools;
• There is always a temporal lag in integrating layers
of information for environmental monitoring &
health and this can effect cumulative population
exposure;
• Regulatory applications can significantly advance in
combination with new monitoring tools (telematic
use, citizens, traffic counts, RS etc);
• Big data are already available for several areas
applications and for assessing specific occupational
hazards. It is the handling that redressing.
• Big data are useless if not aiming to resolve
problems that remain unsolved until now.
