(Big) data for env. monitoring, public health and verifiable risk assessment-new technologies with innovative handling with data gaps
«(Big) Data for
Env. Monitoring, Public Health and Verifiable
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.

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.

Future needs involve Several Disciplines
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
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).
Actual measurements in 2010

• Satellite and UAVs for
High resolution of
High revisit periods are
• In-situ climate sensors:
Not rely only on synoptic
1. GISS ModelE2.
2. Ron L. Miller et.al. measurements since 1850 AGU at the
J. of Advances in Modelling Earth Systems.
Big data for regulatory applications
• Real-time 10min met data
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

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
• 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.
