Unit 9: AWIPS Multi-Source Data Displays Instructional Component 9.1.15 Interactive Cloud Height Algorithm and GOES Sounder Point Retrievals in AWIPS Dan Bikos and Dan Lindsey, CIRA Larry Hinson and Fred Mosher, AWC 1) Introduction
Part 1 deals with the Interactive Cloud Height Algorithm in AWIPS. This feature allows users to obtain a cloud height estimate based on infrared satellite (channel 4) brightness temperatures. Either a nearby raob or a model forecast sounding is used to obtain the cloud height from the retrieved brightness temperature. In order to properly use this tool, the user needs to understand the numbers and letters which are part of the algorithm output. Topics covered include: Part 2 deals with GOES Sounder Point Retrievals in AWIPS. Derived Product Imagery (DPI) (precipitable water, lifted index, etc) has been available in AWIPS for awhile, but the point retrievals are relatively new. Viewing the sounder data in this fashion requires caution - this is what Part 2 of this teletraining session will focus on. Topics covered include:
There are no prerequisites. 3) Teletraining Installation Instructions 4) Training Session Options: B.) Web-based training session - a "stand alone" version viewed via a Web browser, with embedded talking points included. This lesson version may be viewed at any time. These slides are ideal for printing from the web-browser, just print preview first to choose portrait or landscape mode. Best viewed with Internet Explorer or Netscape (prior to version 6). C.) Web-based Visitview session This version uses the VISITview software within a Web browser, may be viewed at any time. It retains all the functionality of the VISITview software which you see in a "live" teletraining session. The talking points are not included in this lesson version, but can be viewed in a separate Web browser (or printed out beforehand). D.) local Visitview session - This is the same version of the lesson used in a "live" VISITview teletraining session, but no connection is made to an external VISITview server. You may download the file off this page and go through the lesson on your own in "local mode" by starting the "visitlocal.bat" file. Talking points are not included in this lesson version, but can be viewed in a separate Web browser ( or printed out beforehand). E.) Audio playback - This VISITview file contains recorded audio and annotations and can be taken at anytime. Certificates of completion for NOAA employees can be obtained through your Science Operation Officer or training point of contact. For detailed information on how to view the recorded session click here. You may either request a DVD (with all VISIT audio playback files) OR download the file (see instructions below): Create a directory to download the audio playback file (it is about 24 MB in size) from one of the following sites: ftp://rammftp.cira.colostate.edu/bikos/audio/cldhgt_audio.exe OR ftp://ftp.ssec.wisc.edu/visit/audio/cldhgt_audio.exe After extracting the files into that directory click on the visitauto.bat file to start the lesson. 5) References/Additional Links Part 1: "Development of interactive cloud height and skew-T diagram algorithms for AWIPS", by Larry Hinson and Fred Mosher (AWC) can be obtained here.
