scribed burns, and seasonal agricultural fires; providing information for air quality forecasting, high-resolution nowcasting, and short-range forecasting of high-impact weather; providing high-resolution weather information for aviation, surface transportation, and coastal waterways; and supporting regional climate monitoring. Improved mesoscale observation networks in urban areas are particularly important for addressing many of these priorities. Identifying ways to enhance and design mesoscale meteorological observing systems (including calibration of environmental data from satellites) so they effectively and jointly serve these and other needs provides an opportunity to dramatically improve analysis and prediction capabilities while sharing infrastructure and costs.

Therefore the current technical context demands an overarching national strategy to integrate existing disparate systems and to define the additional observations needed to achieve the desired result. Furthermore, guidance must be provided on how best to implement a practical, useable, and cost-effective system of truly multi-purpose mesoscale observations. A major implementation challenge is to retain the energy, enthusiasm, and diverse investments that have led to our current condition, while also introducing an appropriate degree of centralization for the purposes of coordination and integration to maximize the national benefit.
