7. ADDRESSING SPECIFIC NEEDS Accurate, well-calibrated continuous three- dimensional multi-variable data collection End-to-end quality products (hardware, software and user customized products) Easy to maintain, calibrate. Quality control methods and procedures that address the needs and limitations of the global market (e.g. Cell phone Technology and PC-based systems) Robust and reliable archiving system for global applications

8. Summary Problem Water resource management Inadvertent weather modification effects Opportunities and research New observing technologies and methods Better models and computing Challenges Infrastructure building Low-tech approach Education Anthropogenic sources of aerosols are impacting cloud and precipitation development around the world.
