.: Estimation of the dynamic coregionalization model and air quality  
monitoring
by integrated ground level and satellite data :.
Joint work with Francesco Finazzi

Abstract:
In this paper, we discuss the dynamic coregionalization model and  
derive new
formulas for the EM algorithm which allows to cover maximum likelihood
estimation for large data sets with structural missing data.

Moreover we discuss its use in air quality monitoring, namely spatio- 
temporal
dynamic calibration of satellite data and mapping daily concentration of
airborne particulate matter. To do this, we consider the problem of  
joint
modelling ground level concentration data and satellite measurements of
aerosol optical thickness (AOT) whose availability is related to  
weather conditions.
