Chair: Martin Burns, NIST. We have made substantial progress on two key use cases – “Approaching Storm to Microgrid” and “A storm is coming through a city”. We will discuss these two Use Cases in Portland. Each Use Case demands the integration and analysis of weather/environmental/climate data from multiple sources and across domains. In addition we will begin to discuss a mapping spreadsheet that compares the key weather standards based on the data groupings of Analogs, CodedValues, Phenomena, Metadata, Alerts, and Geometry. The Use Cases along with the mapping spreadsheet, when complete, will provide the basis of the requirements output of the PAP.
