In 1996, in an attempt to resolve an inconsistency between ozone profile trends obtained from satellite vs. ground-based measurements, the Stratospheric Processes and their Role in Climate (SPARC) project of the World Climate Research Programme (WCRP) initiated a collaboration with the International Ozone Commission (IO3C) to carefully re-evaluate the ground-based and satellite ozone data. This study, headed by the SPARC Panel on Understanding Ozone Trends, did not simply review the published literature but conducted a critical re-analysis and interpretation of ozone vertical profiles.
The NDACC Working Group on Water Vapor announces the publication: ISSI Scientific Report 10: Monitoring Atmospheric Water Vapour edited by Niklaus Kampfer. The aim of the book is to assess in detail in situ and remote sensing techniques presently used to monitor on a regular basis the distribution of atmospheric water vapor.
October 23, 2012 marks the official opening of the the Southern Tropical high altitude NDACC Maido Observatory in Reunion Island. After more than 15 years effort from CNRS-INSU, the Region and the University of Reunion Island, the construction of the Observatoire de Physique de l'Atmosphere (OPAR) was completed in July 2012. The lidars and FTIR instruments are being installed for the long term monitoring of the composition of the atmosphere.
The Demonstration Network Of ground-based Remote Sensing observations (NORS) is a new EU Framework 7 R&D project in support of the GMES Atmospheric Service (GAS) that began on November 1, 2011 and will run for 33 months.
