Develop an overarching vision for an integrated, flexible, adaptive, and multi- purpose mesoscale meteorological observation network Seek to identify specific steps to help develop a network that meets multiple national needs in a cost-effective manner.
Focus primarily on mesoscale observational requirements over the United States and adjacent coastal zones Emphasis on characterizing the planetary boundary layer (defined as extending from approximately 2 meters below the surface to 2- 3 kilometers above)
Forecasting on time scales up to 48 hours The study will provide a practical approach, stressing applications and how to design and implement an enhanced atmospheric observation system in a manner that the resulting information significantly improves users' decision-making.
Address the roles to be played by federal, state, and local government and by commercial entities. In essence, the study will provide a framework and recommendations to engage the full range of weather-sensitive information providers and users in the development of an integrated, multi-purpose mesoscale observation network. This aspect of the study was the committee’s greatest challenge. This aspect of the study was the committee’s greatest challenge.
current sta Characterize the current state of mesoscale atmospheric observations and purposes; Compare benchmarks Compare the U.S. mesoscale atmospheric observing system to observing system benchmarks; desirable attributes Describe desirable attributes of an integrated national mesoscale observing system; The focus is at a high level, well removed from network design.
Identify steps to enhance and extend mesoscale meteorological observing capabilities so they meet multiple national needs; and Recommend practical steps to transform and modernize current, limited mesoscale meteorological observing capabilities to better meet the needs of a broad range of users and improve cost effectiveness.
Weather Prediction and Climate Monitoring Energy Security Public Health and Safety Transportation Water and Food Research and Development A similar approach to the decadal satellite survey.
Literally thousands of organizations including small businesses, Fortune 500 corporations, state agencies, local water management and flood districts, urban air quality authorities, agricultural producers and service providers, and recreation providers, have entered the field of mesoscale observation to further particular interests associated with their mission. These observational assets are clearly market driven and span a wide dynamic range of investment.

Resolving Observations that resolve small temporal and spatial scales of motion and scalar variability.Enabling Observations that do not resolve mesoscale structure but serve to enable mesoscale numerical weather prediction (e.g. lower troposphere profiles with high vertical resolution)
The report is fairly imaginative, aggressive and a bit lengthy. For this reason the NRC went to 14 external reviewers Controversial points helped to stimulate 108 pages of reviewer comments and suggestions. Most technical aspects are straightforward.
