En lägesrapport kom nyligen – tack för tipset, BA. Det är tydligen flera publikationer på gång, och – kors i taket – också ett relevant kapitel i den kommande IPCC-rapporten! Vad tycks om dessa smakprov från den PDF man kan ladda ner i länken ovan?
- 1 FIRST RESULTS: The first physics results from CLOUD  were published in Nature, August 2011 . The measurements represent the most rigorous laboratory evaluation yet accomplished of binary, ternary and ion-induced nucleation of sulphuric acid/ammonia aerosol particles under atmospheric conditions. Several new findings were reported. Firstly, CLOUD has shown that the most likely nucleating vapours, sulphuric acid and ammonia, cannot account for nucleation in the lower atmosphere. The nucleation observed in the chamber occurs at only one-tenth to one-thousandth of the rate observed in the lower atmosphere (Fig. 1). In view of the CLOUD results, the treatment of aerosol formation in climate models will need to be substantially revised since all models assume that nucleation is caused by these vapours and water alone. Secondly, CLOUD has found that cosmic ray ionisation can substantially enhance nucleation of sulphuric acid/ammonia particles—by up to a factor of 10. Ion-enhancement is particularly pronounced in the cool temperatures of the mid-troposphere and above, where CLOUD has found that sulphuric acid and water vapour can nucleate without the need for additional vapours.
- 4 PUBLICATIONS: The publication of the first CLOUD results in Nature  attracted wide interest in the media and scientific press, including articles in The Economist ,Wall Street Journal, CERN Courier , Nature News, and Nature Geoscience . The results were also reported at numerous scientific meetings, including an invited plenary talk at the European Aerosol Conference, EAC2011, Manchester, September 2011. The CLOUD4 and CLOUD5 runs in 2011 have revealed a number of important new findings which are currently being analysed. Several high profile (Nature/Science) manuscripts are in preparation. At least two of these will be submitted for publication before 31 July 2012. This date marks the submission deadline for papers to be eligible for inclusion in the 5th Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC), which is due to be completed by the end of 2013. For the first time, a chapter in AR5 will be devoted to “Clouds and Aerosols”, and it will contain a section on the influence of galactic cosmic rays. In addition to the high profile manuscripts, a further 20 papers are in preparation for submission to Atmospheric Chemistry and Physics, an open access—and highly popular—Journal of the European Geosciences Union. Several papers have already been published [6, 7, 8, 9] and about ten more are expected to be submitted by mid 2012. Fourteen CLOUD abstracts have been submitted to the European Aerosol Conference, EAC2012, Granada, September 2012.
Mycket glädjande att det kommit så långt i processen att att åter bli sund och objektiv vetenskap, efter all smutskastning av speciellt Svensmark.
