1 Sandy Supplemental Project: New AWIPS Data for NWS in Alaska Carl Dierking, Tom Heinrichs, Gwen Bryson, Jay Cable, Scott Macfarlane, Jessie Cherry, Eric Stevens University of Alaska, Fairbanks 05/13/20151

2 Outline Existing products and data distribution Sandy Supplemental hardware/software upgrades New product priorities Challenges Summary 05/13/20152

3 Existing GINA Direct Readout Data Flow 05/13/2015 3 RBG, Hybrid, QPE, & SFR Products, Training & Assessment Fog/Low Stratus & Ash Products, CSPP Processing Pkg Direct Readout Data & Processing VIIRS Single Channel Products Puffin Feeder GeoTiffs, Image Archive LDM DNB enhancements Training & Assessment Operational Use & Feedback

4 05/13/20154 UAF (Big Dog) 3.6 m X-band antenna Processing Seven Sensors: VIIRS, MODIS, AVHRR, CRiS, ATMS, OMPS Raw data archive VIIRS (DNB,I1,I2,I3,I4,I5) GeoTIFF RGBs on Puffin Server GINA Products SPoRT (VIIRS/MODIS RGBs, NESDIS QPE, SFR) CIMSS (Fog/Low Stratus, Vol Ash) GMU (River Flood) CCNY (River Ice) GINA CI Partner Products GINA/UAF Current NWS Alaska Product List

5 05/13/20155 1.Mitigate the risk of a data gap between Suomi National Polar-orbiting Partnership (SNPP) and Joint Polar Satellite System-1 (JPSS-1) 2.Deliver near real-time data (NRT) from JPSS satellites to the National Weather Service (NWS) 3.Advance from best-effort downlink, processing, and distribution toward 24/7 operations Sandy Supplemental Objectives

6 New Product Priorities Increase data frequency with additional sensors (Objective 1: mitigate risk of data gap) Decrease product latency with new processing hardware/software (Objective 2: deliver near real-time JPSS data) Exploit AWIPS2 “truecolor” plugin capabilities and EPDT work to produce composite products (i.e. RGBs) on the client side. (focus on single channel data delivery) Increase color resolution when possible 05/13/20156

10 10 New 3.0 m X,S,L band antenna at FCDAS Fewer pass conflicts Backup antenna at GINA New computer processors Software upgrades Concurrent with NWS communication upgrades Fairbanks Cmd & Data Acquisition Stn GINA/UAF X-band “Big Dog” Todd Paris - UAF Hardware/Software Upgrades

11 NWS Communications Upgrades 05/13/201511 To accommodate increased Satellite data volume, NWS communication line upgrades become operational May- Jun 2015. Significant bandwidth increase between Region Office and Fairbanks, Juneau, and Anchorage WFOs Enables faster and more reliable delivery of satellite products via LDM Includes high-speed network presence at NESDIS FCDAS satellite reception facility

14 Limitations of 8 Bit Color 05/13/201514 SPoRT 24 Hr Microphysics RGB

15 05/13/201515 Low cloud/fog 8 bit image of 24 bit GeoColor Product 8 bit AWIPS II GeoColor Product Color limitation artifact showing low clouds/fog where none exists 15 Artifacts in 8 bit AWIPS I/II GeoColor Product Due to Color Sampling

16 “truecolor” plugin: VIIRS Falsecolor RGB 05/13/201516 AWIPS2 “client-side” composite – three 8-bit single channels (R=I3 G=I2 B=I1) RED: 68.0 (27%) GREEN: 226.0 (89%) BLUE: 217.0 (85%) Sampling displays composite contribution Made possibly by work of SPoRT Experimental Products Development Team (EPDT)

17 “truecolor” plugin: VIIRS Snow/Cloud RGB 05/13/201517 AWIPS2 “client-side” composite – three 8-bit single channels (R=I1 G=I3 B=I5) Composite Dialog Controls color contributions Made possibly by work of SPoRT Experimental Products Development Team (EPDT)

19 3.0 m X,L,S-band antenna New Processing: VIIRS, MODIS, AVHRR (POES & MetOP), OLS (DMSP) 05/13/201519 3.6 m X-band antenna Processing: VIIRS, MODIS, AVHRR, CRiS, ATMS, OMPS Raw data archive DNB VIIRS netCDF4 (I1-5,M1-16) MODIS AVHRR (POES & MetOp) OLS GeoTIFF RGB on Puffin Server GINA Products SPoRT (VIIRS/MODIS RGB, NESDIS QPE, SFR) CIMSS (Fog/Low Stratus, Vol Ash) GMU (River Flood) CCNY (River Ice) GINA Partner Products GINA/UAF FCDAS Expanded NWS Alaska Product List

20 Challenge: AWIPS Time-matching 05/13/201520 For irregularly timed Polar data: AWIPS users could benefit from a mode that steps through multiple sensor imagery in a single time sequence (or) a mode that always places most recent image on top layer.

21 05/13/201521 Himawari data distribution impacts on Bandwidth are still not fully known Himawari, GOES-R, JPSS hardware/software demands will be intensive. Management of a surge in new products could distract NWS forecaster “situational awareness”. Challenge: Himawari/GOES-R

22 Advantage: Resolution & Paralax Correction 05/13/201522

23 05/13/201523 Most popular experimental product for Alaskan NWS forecasters Most useful in the winter when “night” season is long in Alaska. (Also good time for Aurora Borealis viewing.) Advantage: VIIRS DNB

24 Improvements for Data Archive Access Puffin Feeder 05/13/201524 Faster and simpler interface More modular for easier maintenance Android app available Continued support of NWS import into GIS platform

25 Summary: New GINA Products Add additional sensor products (MODIS, AVHRR, DMSP, MetOP) Provide VIIRS in full 24 bit color, netCDF4 format Focus on single channels used for client-side multi-channel products (RGB): – Provide guidance (best practices) on preparation – Provide training on utilization – Assess value and make adjustments as needed Continue to supply Direct Readout data to partners Continue to development and distribution of derived products 05/13/201525
