GOES Microburst Day Potential Index
This index is useful for showing the potential for wet microbursts in the southeast
United States. An index value approaching 1 represents a high risk.
15
GOES High Density Winds
Winds Derived in Several Categories
• Cloud-Drift IR Winds (Imager)
• Water Vapor Winds (Imager)
• Visible Winds (Imager)
• Water Vapor Winds (Sounder)

• Images to be re-mapped in Lambert-Conformal Projection
• Color enhancements will be required to display important
meteorological information (Unique enhancements will be
required for each of 18 infrared channels)
• AWIPS sectors (CONUS, Regional, etc.) still to be defined
• Examples from AMS presentation…

Implementation Schedule/Issues
Prioritized AWIPS Satellite Product Requirements Completed by NWS/OM;
Incorporated Into SPSRB (Satellite Products and Services Review Board)
List for Resource Allocation
AWIPS ‘Build 5’ is First Opportunity for Including New Products/Applications
in AWIPS System - Early/Mid 2000
NWS Will Accept “Experimental” Products Pending Operational
Implementation at NESDIS; ORA (Office of Research and Applications)
Will Distribute Routine “Experimental” Products
Many New AWIPS Products Currently Available on Internet
AWIPS Applications Software Needed for Product Display and Analysis
