Journal ArticleDOI
Global distribution of Earth's surface shortwave radiation budget
Nikos Hatzianastassiou,Nikos Hatzianastassiou,Christos Matsoukas,Christos Matsoukas,A. Fotiadi,K. G. Pavlakis,K. G. Pavlakis,E. Drakakis,E. Drakakis,Despina Hatzidimitriou,Despina Hatzidimitriou,I. Vardavas,I. Vardavas +12 more
TL;DR: In this article, the authors used a radiative transfer model accounting for the key physical parameters that determine the surface SRB, and long-term climatological data from the International Satellite Cloud Climatology Project (ISCCP-D2).
Journal ArticleDOI
Aerosol physical and optical properties in the Eastern Mediterranean Basin, Crete, from Aerosol Robotic Network data
A. Fotiadi,A. Fotiadi,Nikos Hatzianastassiou,Nikos Hatzianastassiou,E. Drakakis,E. Drakakis,Christos Matsoukas,Christos Matsoukas,K. G. Pavlakis,K. G. Pavlakis,K. G. Pavlakis,Despina Hatzidimitriou,Despina Hatzidimitriou,Evangelos Gerasopoulos,Nikos Mihalopoulos,I. Vardavas,I. Vardavas +16 more
TL;DR: In this article, the authors investigated the aerosol optical properties, namely aerosol extinction optical thickness (AOT), Angstrom parameter and size distribution over the Eastern Mediterranean Basin, using spectral measurements from the recently established FORTH (Foundation for Research and Technology-Hellas) AERONET station in Crete, for the two-year period 2003-2004.
Journal ArticleDOI
The direct effect of aerosols on solar radiation based on satellite observations, reanalysis datasets, and spectral aerosol optical properties from Global Aerosol Data Set (GADS)
Nikos Hatzianastassiou,Nikos Hatzianastassiou,Christos Matsoukas,Christos Matsoukas,E. Drakakis,E. Drakakis,Paul W. Stackhouse,Peter Koepke,A. Fotiadi,A. Fotiadi,K. G. Pavlakis,K. G. Pavlakis,I. Vardavas,I. Vardavas +13 more
TL;DR: In this article, the seasonal direct radiative effect (DRE) of natural plus anthropogenic aerosols on solar radiation under all-sky conditions is obtained by combining satellite measurements and reanalysis data with a spectral radiative transfer model and spectral aerosol optical properties taken from the Global Aerosol Data Set (GADS).
Journal ArticleDOI
Long-term global distribution of earth's shortwave radiation budget at the top of atmosphere
Nikos Hatzianastassiou,Nikos Hatzianastassiou,A. Fotiadi,Christos Matsoukas,K. G. Pavlakis,E. Drakakis,E. Drakakis,Despina Hatzidimitriou,Despina Hatzidimitriou,I. Vardavas,I. Vardavas +10 more
TL;DR: In this paper, the mean monthly shortwave (SW) radiation budget at the top of atmosphere (TOA) was computed on 2.5° longitude-latitude resolution for the 14-year period from 1984 to 1997, using a radiative transfer model with long-term climatological data from the International Satellite Cloud Climatology Project (ISCCP-D2) supplemented by data from National Centers for Environmental Prediction- National Center for Atmospheric Research (NCEP-NCAR) Global Reanalysis project, and other global data bases such as TIROS
Journal ArticleDOI

Christos Matsoukas,Christos Matsoukas,Andrew Clive Banks,Nikolaos Hatzianastassiou,Nikolaos Hatzianastassiou,K. G. Pavlakis,K. G. Pavlakis,Despina Hatzidimitriou,Despina Hatzidimitriou,E. Drakakis,E. Drakakis,Paul W. Stackhouse,I. Vardavas,I. Vardavas +13 more
TL;DR: In this article, the authors calculate the monthly components of the Mediterranean Sea heat budget, namely the net shortwave, net longwave, latent, sensible heat fluxes, and heat storage change, for years 1984-2000.
