In the coming decades some kind of ozone recovery is expected, however, it is difficult to predict how, when, and to what extent it will occur. Currently it is discussed how climate change will interact with ozone recovery. Climate models predict an accelerated stratospheric circulation, leading to changes in the spatial distribution of stratospheric ozone and an increased stratosphere-to-troposphere ozone flux. In order to verify or decline the different climate model simulations consistent long-term observations of the vertical More...

On April 4 2012, Dr. Benjamin Torres successfully defended his PhD dissertation "Study on the Influence of Different Error sources on sky radiance Measurements and investment-derived aerosol products in the frame of AERONET" at the University of Valladolid, obtaining the highest score, Apt "CUM LAUDE". This PhD was supervised by Dr. Alberto J. Berjón, Izana Atmospheric Research Center (AEMET), and Dr. Carlos Toledano, Atmospheric Optics Group (University of Valladolid). It also counts with the participation of Dr. Oleg Dubovik, More...

The water vapour stable isotopic composition is affected by fractionation during phase changes. Measurements of water vapour isotopologues therefore provide complementary information on the water budget when combined with humidity, because they record the integrated history of phase changes within a given air mass. In this context, two new papers, published recently in the Journal of Geophysical Research, examine how H2O and HDO measurements in water vapour can be used to detect and diagnose biases in the representation of processes More...

  The Meteorological State Agency of Spain (Climatology and Operative Applications Section) and the Institute of Meteorology, Portugal (Divisão de Observação Meteorológica e Clima) have published the climate Atlas of the Archipielagos of the Canary IslandsCanary Islands, Madeira and the Azores.The climatic elements analyzed in this Atlas are Air Temperature and Precipitation, based on observation data of meteorological and precipitation stations of national networks of Portugal and Spain. Climatological normals (mean values) correspond More...
