Researchers from Karlsruhe Institute of Technology (KIT, Karlsruhe, Germany) have for the first time used several mobile Fourier Transform Spectrometers for detecting the CO2 emitted by a large metropolitan region in solar absorption spectra. The campaign was performed in June and July 2014 around Berlin, Germany, using five EM27SUN spectrometers (this type of spectrometer has been developed in a collaboration between researchers at KIT and Bruker Optics GmbH, Ettlingen).
The 2015 NDACC Steering Committee meeting will take place 12-16 October 2015 at the Scripps Institution of Oceanography in La Jolla, CA. The plenary sessions will run Monday through midday Thursday. There will be a possible tour of Scripps on Thursday afternoon, and a possible site visit to Table Mountain and the NASA Dryden Aircraft Operations Facility (DAOF) in Palmdale on Friday. More information will be posted as it is available.
The annual meeting of the international Steering Committee (SC) for NDACC was held at the Belgium Science Policy Office in Brussels. Agenda items included a detailed report from the NDACC Data Host Facility on data archiving status and data utilization. This was followed by reports from the various Working Group (WG) Representatives on the SC (Dobson and Brewer, FTIR, Lidar, Microwave, Sondes, Spectral UV, UV/Visible, Satellites, Theory and Analysis, and Water Vapor).
At the 2014 NDACC Steering Committee meeting in Brussels (3-5 November) Dr. Anne Thompson, Scientist at NASA’s Goddard Space Flight Center (Maryland, USA) was elected Co-Chair of NDACC for a term from 2014-2017. Since 1998, Thompson has been the Principal Investigator of the SHADOZ (Southern Hemisphere Additional Ozonesondes) network that affiliated with NDACC in 2009. Thompson replaces Dr. Stuart McDermid of NASA’s JPL, who retired last year.
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.
