4. specialises in investigations of atmospheric processes on the smallest scales and their interaction with larger scale phenomena. Understanding small scale processes is allows to describe precisely many dynamic and thermodynamic interactions in the atmosphere as well as to increase our ability to simulate and predict global circulation and climate.

6. Outline: originally the project was planned for 36 months (2003-2005). EU allowed for 12 months extension (2006). Types of activities undertaken: Scientific - support of participation in international field campaigns; - organization of special session on ICCP 2004 Bologna. Exchange - visitor programme for European young scientists CESSAR; - support of visits of CESSAR students, young researchers and faculty staff in European research centres; - support of conference presentations of CESSAR's students and researchers; short-term visits of foreign scientists to CESSAR. - short-term visits of foreign scientists to CESSAR. Education - summer schools/workshops with world-class scientists giving lectures to Polish students and young researchers; - enhancement of educational offer at CESSAR. Other- library modernization; - information and communication (www).

7. problems (failures) and actions undertaken: - only two log term foreign post-doc visitors (dr Gintautas Stankinavicius Lithuania, Dr Jens Bange, Germany); /support of Polish graduate students and post-docs (short and longer scientific stages at CESSAR); - technical problems with the WWW server (not fully functional) /an attempt to build a more functional one undertaken.

8. success: - organisation of summer schools/workshops: 2004 -”Physical Mechanisms of Climate Change”, Piaski, 21-24 June 8 lecturers – scientists from EU and US, 44 participants – mainly graduate students and young scientists from Poland. 2005 - “Modern Techniques in Atmospheric and Climatic Studies”, Kościelisko, June 19-23 7 lecturers – scientists from EU and Canada, 52 participants – mainly graduate students and young scientists from Poland.

9. summary: - increase of Ph.D students/candidates from 5 to 9, collaborative doctorates with CNRM, KNMI, NCAR; - increased activity of M.Sc/Ph.D students – organization of scientific camps, student seminars, participation in field experiments, construction of simple scientific equipment. - increased participation in ZFA/CESSAR seminars (typically from ~15 to ~40), participants from outside Warsaw), popular website; - international conference support: all ph.D. candidates with presentations been supported (~20 presentations); - substantial short term exchange between CESSAR and EU (~20 visits/year, both directions); - reform of M.Sc. studies, substantial improvement in communications (website), modernization of the library; - support of participation in the international collaborations (field campaigns: BBC2 and RICO, ICCP conference, small research projects).

10. synergies: - modernization of the ZFA/CESSAR headquarters; - organization of the international measurement campaign in Warsaw (SAWA-2005, remote sensing of aerosols); - development of the CESSAR/ZFA laboratory; - attraction of M.Sc students from the country; - promotion of EU R&D projects.
