Weather Service Warnings Use Case
Weather Service Warnings; May session of the ESIP Discovery Cluster
May 18, 2023
Meeting Introduction
Weather service warnings are issued and distributed to the masses to deliver accurate and actionable information to save lives and property in response to weather events. The discovery cluster has invited Nelson Vaz, a warnings coordinator for the National Weather Service, to share the repeatable processes that the weather service uses to forecast and issue warnings. What tools do NWS forecasters use to generate warnings, and how is this information disseminated to end users to provide locality specific, timely, and actionable information.
The Discovery Cluster has developed a Usage Base Discovery (UBD) paradigm for dataset discovery. UBD could help document how expert users like meteorologist derive actionable information from data, like weather models and satellite products. Dataset usages are cataloged and documented in a knowledge graph to help make explicit how expert users apply Earth Science information to inform specific derived products and analyses. The outcome of this meeting with Nelson Vaz may be captured as submissions to the UBD knowledge graph. However, the weather service warnings use case provides more than this, as the weather service is an example of effective information delivery in response to specific events.
The Discovery Cluster has previously tried to understand the specific distillation of very complex Earth Science information into clear and actionable end user information, like in the case of flooding information (See UBD Use Case). Are there other uses for the information that weather service staff are accessing to develop warnings, and how could the general public discover this additional information in a timely fashion? What improvements do we need to make to the UBD tool to address this and similar event based use cases (eg. wildfire response), and what can we glean from how the Weather Service disseminates this information for weather warnings?
