  1. 1. FY12-13 GIMPAP Project Proposal Title Pagedate: 7 August 2012 06 Title: Using GOES and NEXRAD Data to Improve Lake Effect Snowfall Estimates Status: Progress Report Project Leads: Mark Kulie (CIMSS,Univ. of Wisconsin-Madison), mskulie@wisc.edu Other Participants: Andrew Heidinger (NOAA/NESDIS/STAR/ABSP), Andi Walther (CIMSS/UW-Madison), Ralf Bennartz (CIMSS/UW-Madison)

  2. 2. Project Summary • Develop, test, and implement GOES lake effect snow (LES) snowfall estimate product • Augments NEXRAD coverage over Great Lakes • Synergistic GOES/NEXRAD data application • Utilizes CIMSS GOES-R Proving Ground • Empirical GOES/NEXRAD relationships • NWS nowcasting applications • Useful real-time product • LES advisories/warnings

  3. 3. Motivation / Justification LES impacts: • Prodigious snow amounts • Hazardous weather • Great Lakes hydrology • Locally variable • Difficult to forecast • Radar detection deficiencies Marquette, MI NWS Web Page: http://www.crh.noaa.gov/images/mqt/0809snow.jpg

  4. 3. Motivation / Justification NEXRAD 1734Z Terra MODIS 1725Z

  5. 3. Motivation / Justification NEXRAD 1638Z Terra MODIS 1635Z

  6. 4. Methodology • “Calibrate” GOES product with NEXRAD • NEXRAD L2 and/or NMQ gridded radar products • ~100 km range for calibration/match-ups • Develop empirical relationships • NEXRAD snowfall rates (Ze-S) • Empirically relate NEXRAD snowfall rates to GOES cloud properties • Effectively extend NEXRAD coverage • CIMSS GOES-R Proving Ground essential component

  7. 5. Expected Outcomes • Create LES GOES/NEXRAD testing dataset • KMQT/KAPX/KGRR initial focus • KBUF/KTYX/KCLE later focus • GOES LES operational snowfall rate product (Great Lakes focus)

  8. 6. First Year - Preliminary Results • Project starts 1 Aug 2012 • Initial NWS Outreach • Test case identification

  9. 7. Possible Path to Operations • Proof-of-concept, demonstration phase • CIMSS GOES-R Proving Ground • Outreach and feedback • NESDIS Satellite Analysis Branch • NWS offices (e.g., MKX, MQT, APX, GRR, BUF, etc.) • Operational implementation

  10. 8. FY13 Milestones • Compile case studies w/ MQT NWS WFO collaboration • Identify useful GOES cloud products (e.g., cloud top height, optical thickness, cloud phase, microphysics, etc.) • Develop NEXRAD/GOES snowfall rate relationships • Process 2011/2012 Winter Season w/ ground validation • Demonstration phase early 2013 Winter Season

  11. 9. Funding Request (K)

  12. 10. Spending Plan FY13 • FY13 $60,000 Total Project Budget • Grant to CIMSS- • % FTE - ~40% ($50,000) • Travel - $5,000 (Travel to NWS sites, NESDIS, Great Lakes Operational Weather Conference) • Publication charge - $5,000 • Other - • Federal Travel – • Federal Publication Charges – • Federal Equipment - • Transfers to other agencies – • Other -
