The LDM is freely available to all, and is in use in a variety of different contexts around the world. Please feel free to download and use it. >As the Severe >Weather Liaison, I am responosible for notifying the emergency >management and decision-making officials across the state of impending >weather watches/warnings issued by the NWS and in creating forecasts to >relay the threats. I currently have a Dell Desktop with Redhat Linux >with 2 GB ram and over 200 Gigs of hard disk space. Is this software >supported on Linux? Yes, Linux is one of our supported platforms. >Any help you can provide in setting up the program >would be helpful.

The easiest thing to do is to work your way through the online documentation for the LDM. The Unidata LDM homepage is: http://my.unidata.ucar.edu/content/software/ldm/index.html The current release is LDM-6.2.1, so you should click on that link and work through the information included: http://my.unidata.ucar.edu/content/software/ldm/ldm-6.2.1/index.html The LDM Basics and LDM Tutorial should quickly get you to the point of having a functioning LDM. After you get an LDM built, how are you planning on using it? Is your email more than an inquiry into access to and use of the LDM software? I.e., are you looking to join the Unidata Internet Data Distribution system? If yes, I must tell you that the Unidata IDD is not an "operational" system. Rather, it is an effort that is comprised of mostly university departments cooperating with one another to share mostly real time data. There are no guarantees that you will receive all of the data that you want/need even though most sites do their utmost to keep things running smoothly. If you are looking for a source of real time data to be used for the protection of life and property, then you would do well to investigate purchasing a NOAAPORT reception system from any of the commercial vendors that are providing this service. If, on the other hand, you would like to participate in the IDD knowing and accepting the parameters under which it operates, then we will help identify a university near you that would be willing to relay you data. >Jason Caldwell >Severe Weather Liaison >SC State Climatology Office >803-734-0039 Cheers, Tom Yoksas -- NOTE: All email exchanges with Unidata User Support are recorded in the Unidata inquiry tracking system and then made publicly available through the web.
