  1. Poster 635 An Overview of CIRA’s Contribution to the GOES-R Proving Ground Ed Szoke1,2, Renate Brummer1, Hiro Gosden1, Steve Miller1, Mark DeMaria3, and Deb Molenar3 1Cooperative Institute for Research in the Atmosphere (CIRA) 2NOAA/Earth System Research Laboratory (ESRL)/Global Systems Division (GSD) 3National Environmental Satellite, Data, and Information Services, Center for Satellite Applications and Research (NESDIS/STAR) Overview CIRA WFO PG Products – Part 1 CIRA WFO PG Products – Part 2 CIRA is an active partner in the GOES-R Proving Ground (PG), interacting with a number of National Weather Service (NWS) Weather Forecast Offices (WFOs), and National Centers (see below). Example of CIRA GeoColor and Low cloud/Fog products compared to AWIPS IR and fog imagery (1100 UTC/5 Mar 10) CIRA synthetic imagery created from the NSSL WRF-ARW model run at 4 km horizontal grid resolution at 0000 UTC, out to 36 h. Shown are 24-h forecasts valid 0000 UTC 12 Jan 2011. CIRA PG Products (see http://rammb.cira.colostate.edu/research/goes-r/proving_ground/cira_product_list/) AWIPS IR image AWIPS 11-3.9 micron image Simulated Band 9 Simulated Band 11 The GeoColor product uses layering techniques and also combines current GOES imagery with background imagery (NPOESS in the GOES-R era) to show the city lights at night. Fog and low clouds are given an orangish color. In the low cloud/fog product (also know as the “shortwave albedo product”) low clouds/fog are white at all times. GeoColor image (nighttime version) Low cloud/fog image (nighttime version) Simulated Band 10 Simulated Band 13 CIRA Cloud/snow Discriminator products compared to AWIPS visible and IR imagery for clouds over snow on 5 Jan 2011 AWIPS Visible image at 1831 UTC AWIPS IR image at 1831 UTC ORI product valid at 0900 UTC 18 Dec 2010 Low-level reflectivity at 0900 UTC 18 Dec 2010 magenta = higher, ice phase clouds The Orographic Rain Index (ORI) product is an example of a derived product that is created by combining the CIRA blended Total Precipitable Water product with short-range forecasts from the GFS to produce an index related to orographically induced precipitation. yellow = lower, liquid phase clouds clouds (yellow/light green) CIRA NWS/WFO Partners and Status snow = white snow = white, bluish-white Cloud Layers and Snow Cover Discriminator Product at 1807 UTC Cloud/snow Discriminator Product at 1810 UTC ORI product overlaid with AWIPS topography imge CIRA Cirrus Detection Product The Cirrus Detection Product is a MODIS-based product that uses several channels (1.38, 3.9, 6.7, and 11µm) to detect cirrus in daytime and nighttime imagery. The cirrus is then given a distinct color, as seen in the examples. Forecaster Feedback on Proving Ground Products The GOES-R Proving Ground strongly encourages forecaster feedback. Based on the forecaster’s comments the PG product developers can change and improve their products. Feedback is being provided verbally, via on-line forms, via comments in shift logs, via email, by using BLOGS, and by mentioning the performance of a product in AFDs (see figure below).
