Hurricane Irene: 08-26-2011 GOES-13/NASA AMSR-E

Large Hurricane

Remove doubt Small inner

eye Outer rainband ? huge radius

Readily maps storm structure ? Intensity correlation

Tropical Cyclone Monitoring Needs

TC Monitoring Needs:

? Storm location, structure, and intensity anywhere (24/7) ? Mitigate vis/IR imagery limitations (cloud obscuration) NRL Microwave Sensor Efforts

? Tap into near real-time microwave sensors ? microwave imagers (SSM/I and TMI) ? microwave sounders (AMSU-B)

Global resource: Public accessible web page

? Process satellite data for TCs in all basins ? Provide one-stop-shop for TC microwave products

 Transition R&D demonstrations to operations: Fleet Numerical Meteorology and Oceanography Center (FNMOC)

Tropical Cyclone Web Page

Transition to operations:

? Need 24/7 support ? NRL works 8hr/day, 5 days/week ? Things happen: power interruptions, computer issues

Fleet Numerical Meteorology and Oceanography Center

? Picked up the tasking to support JTWC and NHC ? National center of excellence for microwave imagers ? Involved in SSM/I cal/val since day 1

How did transition succeed?

? Same digital near real-time data sets ? Same SeaSpace TeraScan software early on for processing ? Small dedicated core teams collocated, little turnover ? Collaborative exploratory research and transition sponsoring
