  1. GOES-R PG Product Usage atWFO Omaha, NE (OAX)(Low Cloud/Fog , GeoColor, and UWCI) Daniel Nietfeld Science and Operations Officer (SOO) dan.nietfeld@noaa.gov

  2. OAX History with GOES-R PG • Ingesting products since ~ March 2010 • Low Cloud/Fog, GeoColor • CI products since September 2010 (stable) • MODIS/Snow Cover off and on since Jan. 2011 (mostly off due to local LDAD/bandwidth issues) • Forecaster usage is largely a function of product timeliness and reliability (availability) - can’t stress this enough • Have had diverse weather conditions

  3. The WFO “Backdoor” : LDAD Major WFO Challenge: GOES-R Proving Ground Products are not on the SBN so they must get into the WFO via the LDM/LDAD “backdoor” which is getting clogged

  4. OAX Forecaster Feedback:Low Cloud/Fog Product • Low Cloud/Fog product is superior to the legacy product (or at least it is used more) • One year of forecaster “preference” feedback • LC/F product does an especially good job of distinguishing between multiple cloud layers at varying heights • LC/F product is the primary imagery used at night

  5. March 10, 2011 Fog FormationLegacy 11-3.9 micron image – where is the fog? Low Clouds (mostly MVFR) Note the dense fog report

  6. CIRA Low Cloud/Fog Product Highlighting the snow field which is cooling the air to result in patchy valley fog formation Snow has a low reflectivity in the shortwave region

  8. GeoColor Products

  9. OAX Forecaster Feedback:GeoColor Product • Also does a great job of distinguishing between varying layers/heights • Need more experience with assessing the opacity of the clouds, but feedback is positive • City lights do help with geo-referencing • Land colors also help with distinguishing clouds from land and identifying land features • Thunderstorm Anvils don’t show detail (OTs, etc…)

  10. Legacy Visible CB top details visible

  11. Geo Color CB top details less visible But… identification of land features far superior!

  12. UW CI Products • Ingesting products since summer 2010 • When used alone, we “experienced” the stove-pipe • Forecasters want this product and want to use it, because CI is very important • Two CI challenge scenarios: • Standard afternoon convection • Nocturnal, elevated CI (usually on LLJ) ~ 4am-5am • Critical to incorporate other environmental parameters / sources / “ingredients”

  13. Positive Detection Case2210 UTC 10 April 2011

  14. Cloud Top Cooling Rate with METARs

  15. UW CI with RUC CINH field “edge of cap” Thermodynamic Environment Supported Convection: CAPE = 1420 J/KG CINH = -54 J/kg

  16. False Alarm Case2000 UTC 10 April 2011 No positive buoyancy (zero CAPE)

  17. Convective Initiation • COMET COOP Proposal with U. of Nebraska • Evaluate Statistics on UWCI POD, FAR • Incorporate other environmental parameters • Explore “fusion” of various data sources • What environmental products are useful ? • What thresholds, etc… lead to best results ? • Can GIS be utilized as a proxy to create the “Artificial Intelligence” ??

  18. Conceptual Model for “Intelligent CI” • Want to add UW Ice Exclusion Zone to AWIPS • Want to layer parameters to determine environments that will often show positive CI Explore with GIS ??? Resulting CI inclusion zone Ice exclusion zone CAPE values > 100 J/KG CINH values < 80 J/KG LCL level upward vertical velocity Some other useful parameter Just an example of parameters

  19. The “Evaluation Challenge” • Forecaster Challenges: • What do we say? (need a usefuleval. form) • Too busy with other duties, weather, etc… • OAX alternative solution: utilize cheap University Students! • Partnering with Universities • Informal (Student Volunteers, SCEPs, etc…) • Formal COMET Project (s)

  20. AWIPS II Capabilities • OAX “flips the switch” from operational AWIPS1 to AWIPSII on July 17 (2 months from now) • Raytheon has been experimenting with enhanced satellite visualization • AWIPSII looks promising for satellite data
