Part-II(2007-2010)•Implementation of the CEOP-II Integrated Observation and Data System for the Global Energy and Water Cycle as planned in Part-I above; •Submit CIMS Results as a Contribution to WCRP Pan Monsoon Study;•Apply WESP results to an Extension of Down-scaling and transferability Studies and, thereby, as a contribution to the Integrated Water Resources Management (IWRM) process which is designed to assist countries in their endeavour to deal with water issues in a cost-effective and sustainable way.•Undertake and conclude a Cold Region Study in Cooperation with the WCRP Climate and Cryoshpere (CliC) Project and the International Polar Year (IPY) effort•Undertake and advance scientific goals related to understanding and defining Extreme Event Mechanisms•Undertake and advance knowledge of the interactions between Aerosols and the Water Cycle.
