How SC5 is being treated within the BDE project.

1. THE ROLE OF SC5 IN
THE BDE PROJECT
NCSR “Demokritos”
6 November
2017

2. Physical background
 Societal Challenge 5: Climate action,
environment, resource efficiency and raw
materials
 The earth’s atmosphere is the physical
background of the pilot use cases developed
for SC5 by NCSRD in the framework of the
BigDataEurope project

3. Atmosphere – related
applications
 Weather prognosis
 Climate change prognosis
 Air pollution abatement / early warning /
countermeasures
o Anthropogenic emissions: routine (industry,
transports, domestic, etc.), accidental (nuclear,
chemical), malevolent (terrorist) – unannounced
releases
o Natural emissions (e.g., volcanic eruptions)
11-oct.-16www.big-data-europe.eu

4. Tools for atmospheric
applications
 Measuremen
ts (from earth
or space)
o Temperature
, wind
velocity,
humidity,
etc.
11-oct.-16www.big-data-europe.eu

5. Tools for atmospheric
applications
 Measurements
o Concentrations of
pollutants (gaseous,
particulate)

6. Tools for atmospheric
applications
 Computational modelling
o Weather prognosis, climate change
 Ensemble weather forecasting
o Dispersion and transformations of pollutants
 Emergency response
 Air quality (routine emissions)

7. Computational
modelling
 Weather prognosis
o Computation of wind
field: sea breeze in
coastal areas
11-oct.-16www.big-data-europe.eu

8. Computational modelling
 Climate change and
impacts
o Dynamical
downscaling from
global to regional and
local scales
11-oct.-16www.big-data-europe.eu

9. Computational modelling
11-oct.-16www.big-data-europe.eu
 Local scale
dispersion
modelling:
o Ground deposition
and internal dose
following a
hypothetical RDD
explosion in a real
city centre QUIC Model, installed and run in NCSRD with the
financial support of EC DG Home, project IMAGES

10. Computational modelling
11-oct.-16www.big-data-europe.eu
 Regional scale
dispersion modelling
o Dispersion of ash from
the Eyjafjallajökull
volcano in Iceland
Dispersion by DIPCOT model,
NCSRD
Meteorological data produced by
WRF

11. Computational modelling:
Global-scale dispersion, Fukushima
accident
11-oct.-16www.big-data-europe.eu
2 days 4 days 6 days
8 days 10 days 12 days
HYSPLIT, NOOA, US model, run by NCSRD

12. Computational modelling
 Emergency
response
o Dispersion of
radioactive
pollutants
(JRODOS)
o Decision Support
Systems handle
large databases
11-oct.-16www.big-data-europe.eu

13. Computational Modelling:
Air quality – photochemistry
11-oct.-16www.big-data-europe.eu
Photochemistry by CMAQ, meteorology by WRF, run by NCSRD

14. Tools for atmospheric
applications
 Combination of model and measurements →
“data assimilation”
o Weather forecasting: initialization and 4DDA
o Dispersion “inverse” modelling for unknown
source estimation and sensitivity assessment
 The 2nd BDE SC5 pilot use case presents a
tool for estimation of unknown source location

15. Scales of atmospheric motions
11-oct.-16www.big-data-europe.eu
• Atmospheric
motions consist of
interconnected
eddies with vast
range of size- and
time-scales

16. Connection to BDE
 The atmosphere is a complex system
 To describe it we use complex partial differential
equations
 The equations are solved numerically on computational
meshes consisting of up to millions or tens-of-millions
points
 Large volumes of monitoring data are also assimilated
 Computer capacity increases
 Big Data tools become necessary 11-oct.-16www.big-data-europe.eu

17. Conclusion – Aim of pilot use
cases
 Atmospheric-related applications produce or
use large volumes of (possibly heterogeneous)
data
 To demonstrate ways that tools provided by
BDE can contribute to more efficient
management / processing / exploitation of
these data
