September 16, Day of the Ozone Layer. Contribution of the Izaña Atmospheric Research Center to the ozone layer monitoring and research activities.
Since 1995 we celebrate the September 16th the International Day for the Preservation of the Ozone Layer (http://ozone.unep.org/new_site/en/ozone_day_details.php). This year we take this opportunity to present the activities we do at the Izaña Atmospheric Research Centre in relation to the monitoring and investigation of the ozone layer, and show the most important conclusions of the state of the ozone layer 2014 report, recently published by the United Nations. The Izaña Atmospheric Research Center (CIAI) has greatly contributed to More...

The state of greenhouse gases in the atmosphere based on global observations through 2013
  On September 9th, 2014, the World Meteorological Organization (WMO) published its tenth annual atmospheric greenhouse gas bulletin (click here to download the bulletin in pdf format), based on global observations through 2013. Most of these measurements were carried out at stations of the Global Atmosphere Watch (GAW) programme of the WMO. In particular, Izaña Atmospheric Research Center (CIAI) of the Meteorological State Agency of Spain (AEMET) contributes with highly precise and accurate measurements carried out at the Izaña global More...

New paper published in Atmospheric Measurement Techniques Discussion entitled "Empirical validation and proof of added value of MUSICA's tropospheric δD remote sensing products" by Schneider et al.
Within the project MUSICA (MUlti-platform remote Sensing of Isotopologues for investigating the Cycle of Atmospheric water) tropospheric water vapour isototopologue remote sensing and in-situ observations are carrying out. This paper presents a first empirical validation of MUSICA’s H2O and δD remote sensing products (generated from ground-based Fourier Transform InfraRed spectrometer, FTIR and a space-based Infrared Atmospheric Sounding Interferometer, IASI). As reference well calibrated in-situ measurements were used. One of these More...

African dust outbreaks over the western Mediterranean Basin: 11-year characterization of atmospheric circulation patterns and dust source areas”, paper published in Atmospheric Chemistry and Physics
  In this paper the occurrence of African dust outbreaks over different areas of the western Mediterranean Basin were identified for the period 2001-2011, and the main atmospheric circulation patterns causing these episodes were objectively characterized. For this purpose, two different but complementary methods for the classification of atmospheric variable fields (K-means and Principal Components) were used. Also, the potential source areas of mineral dust associated to each circulation pattern were identified by a trajectory statistical More...

“Aerosol characterization at the Saharan AERONET site Tamanrasset” paper published in Atmospheric Chemistry and Physics (ACP-Discussion phase)
This paper presents an analysis of more than two years of columnar atmospheric aerosol measurements (2006–2009) at Tamanrasset site. Tamanrasset is a strategic site for aerosol research placed in the heart of the Sahara. Figure 1. Location of Tamanrasset station and Cimel sun-photometer set-up.   For this analysis, AERONET level 2.0 data supplemented by corrected level 1.5 data (KCICLO method) were used. The annual variability of aerosol optical depth (AOD) and Angstrom exponent (AE) has been found to be strongly linked to the More...
