Introduce JAG/LDS Goals

• Review TOR– The JAG/LDS will provide a National Lightning

Capabilities Document that will achieve the following:

• Be a mutually agreed upon set of capabilities that will fulfill the requirements of the member agencies.

• Fully describe the capabilities such that a contractor can build the system based on what is in the document.

• Be delivered to the NWS by June 2008.

• See Excel spreadsheet• Due to OFCM 30 Mar 08• All agencies (DOC, USAF, USA, Navy, DOI, FAA, BLM,

NASA) should provide a list of capabilities using the table provided

• Are there any descriptors missing?– Impact if capability not available?– Flash vs stroke reporting?– Polarity?– Cloud to cloud needed?– Data Format?

• Add descriptive columns, pages, or maps as necessary to capture your agency’s needs

12


• Should we agree on a common non-proprietary data format?

• Need to agree on common description (intersection of all of our needs) for different geographical areas. – Common set of capabilities for CONUS and territories– Common set of capabilities for Pacific and Atlantic– Common set of capabilities for Europe etc etc

• We can capture those needs that fall outside the intersection of our common needs and make them a part of the data capabilities document.– Separate description for Spacelift, range, EOD capabilities etc
