Q17. Q18. Q19. REVIEW  QUESTIONS How are NODDS products obtained? What types of products can be obtained from NODDS? What is a significant processing advantage of NODDS? JOINT METOC VIEWER (JMV) LEARNING   OBJECTIVES:   Identify   how products are obtained from the Joint METOC Viewer  (JMV). Identify  the  manual  that explains the use of JMV. Describe the major features of the Joint METOC Viewer (JMV). Identify the types of products available from JMV. The Joint METOC Viewer (JMV) is an easy-to-use tool for displaying and annotating meteorological and oceanographic data. JMV is quite similar to NODDS, although JMV products are obtained exclusively via the Internet. JMV consists of software that utilizes web technology  (INTERNET/NIPRNET/SIPRNET)  as  a means  to  make  FNMOC  environmental  products available to regional METOC centers. These products can  then  be  obtained  by  facilities,  detachments,  and other DOD users who have web access. The computer hardware and operating system combination necessary to run JMV is a PC with Windows 3.1, Windows 95, or Windows  NT.  In  any  case,  the  user  must  have  a working knowledge of Windows. Products for display in JMV are accessed only from Naval METOC regional centers  or  directly  from  FNMOC.  Once  downloaded, products can be viewed, customized, exported, or archived. There are far more display options and graphics tools available with JMV than with NODDS. Detailed information concerning JMV is provided in   the   Joint  METOC  Viewer  User  Manual, FLENUMETOCCEN  P-352,  which  can  be  downloaded from the FNMOC website. A list ofproducts from JMV is also contained in the FNMOC Products Manual. To request an account for JMV and the web page, users must be members of the Department of Defense or authorized DOD contractors. All requests for accounts should  be  sent  to  the  FNMOC  web  master  at: http://www.webmaster@fnoc.navy.mil  (accessible through the FNMOC web page). Routine requests for new areas or changes to the data contained in an area can also be made by contacting the FNMOC web master. JMV FEATURES JMV  is  unique  in  its  approach  to  environmental data communications. A JMV thumbnail (defined regional area) and associated product list is defined on the host computer at the regional center. The data is then stored on the host computer and any authorized user can download it to their computer using the JMV software package. Once the raw data is received by the computer,  the  required  contouring,  streamlining, shading, etc., is performed automatically until all products are in a ready-to-display format. The user has the  ability  to  select  contour  intervals,  change  colors (both screen and printer), and can also select unit preferences (Metric/English). JMV has the ability to overlay up to three different fields at once and display individual sequence loops. Figure 2-5 is an example of a surface pressure analysis from JMV. JMV PRODUCTS JMV  currently  provides  only  the  regional  centers (host computers) with the capability to define areas of interest  and  select  the  different  gridded  products  for  the defined areas. Other users must notify the appropriate regional center of their area and product requirements via telephone or email. The obvious limitation to this process is that the geographical areas and associated product lists are predefined by the regional centers and by  FNMOC.  This  problem  will  eventually  be eliminated as more powerful servers are introduced. Software upgrades to JMV will also allow for slide show  presentations,  tropical  cyclone  warning  plots,  a "ship  route"  display  feature,  and  other  graphics improvements. A list of JMV products is detailed in section  2.3.5.  of  the  JMV  Users  Guide.  Watch personnel at each of the regional centers provide 24- hour support for JMV. There are several other products that are currently available from FNMOC via the NIPRNET. These include  various  satellite  products,  meteorological  and oceanographic forecast products, and forecast model reports, summaries, and tendency reviews. Check the FNMOC website for details. Q20. Q21. Q22. REVIEW  QUESTIONS How are JMV products obtained? What is the easiest method to obtain the "Joint METOC Viewer User’s Manual"? JMV defined-areas are established by what activity(s)? 2-16
