Christoforos' research is now focused on satellite observations of sea surface temperature and aerosols in support of forecasting applications, climate monitoring and environmental services.
Christoforos works on the quality of Sea Surface Temperature (SST) from satellite observations (mainly ATSRs) for the CCI project funded by ESA. The ATSRs (ATSR-1, ATSR-2 and AATSR) were satellite instruments on board ERS-1, ERS-2 and ENVISAT respectively, specifically designed to provide high quality SST observations. Due to their well calibrated blackbodies and dual view capability, the ATSRs produced more accurate SST measurements than any other satellite instrument and the majority of in situ instruments. In total, the three ATSRs have provided about 20 years of global SST observations from August 1991 to April 2012.
Currently, Christoforos is involved in a project testing the stability of AVHRR measurements on board MetOp-A. The results of this study will determine whether AVHRR is suitable to fill the gap in high quality SST measurements, which are essential for climate monitoring, until the launch of the SLSTR instrument on Sentinel-3.
Also, he continues his research on aerosols from satellite observations, especially from CALIOP space lidar on board CALIPSO.
Christoforos joined the Met Office's Satellite Applications group in 2013.
Before this, he spent more than two years at the Laboratoire de Météorologie Dynamique/CNRS in France as a post-doctoral research fellow. There, he worked on the characterisation of dust aerosols using observations from satellite instruments (CALIOP, AIRS, IASI and MODIS) for the MACC II project funded by the European Union (FP7).
Christoforos obtained a PhD from University Pierre et Marie Curie (Paris 6) in France. His research focused on lidar observations and atmospheric models (dispersion, chemistry and radiative) to study the radiative and transport processes influencing the vertical variability of tropospheric ozone and aerosols in the Mediterranean region.
He gained a Masters degree in Mathematical Modelling from National Technical University of Athens in Greece by focusing on stochastic models of pollutants' diffusion in the atmosphere. Previously, he received a diploma in Applied Mathematics and Physics also from National Technical University of Athens, using the lidar remote sensing technique to study the vertical distribution of aerosols and atmospheric boundary layer over Athens.
