15CONLUSIONS AND OUTLOOK
- Our MM5-CHIMERE system implemented over Italy
require further development and testing,
especially regarding the emission inventory - More test cases
- A dedicated campaign? CETEMPS is involved in a
preliminary project founded by ASI to integrate
Earth Observations and Air Quality monitoring and
forecast
16OUTLOOK HI RESOLUTION
Use of the Gridded Population Data at 0.083 x
0.083 resolution (available on the web) to
dissagregate the EMEP emissions currently
implemented into CHIMERE
17OUTLOOK GEOS-CHEM B.C.
- GEOS-CHEM global CTM developed at Harvard (D.
J. Jacob) - CETEMPS is part of the GEOS-CHEM users
community - Use the operative GEOS-CHEM forecast at 2 x
2.5 resolution (soon available) as boundary
condition to CHIMERE
