Data Communications Information

Distribution method  LDM

 Text/XML Viewer (Surface Observation Datasets Only)
Hostname(s)
IP address(es)

You can receive real-time data or obtain access to the on-line archive of saved real-time data by requesting an ftp, OPeNDAP or Text/XML Viewer account. For real-time data, LDM access is also available. OPeNDAP and Text/XML Viewer accounts are recommended for those who have a need for data on-demand, as contrasted with continuous real-time access. In general, users who require a continuous datafeed will get better performance by accessing the data via ftp or LDM.

Also note that at this time, the Text/XML Viewer can only be used for the surface observation datasets.

If you will be receiving the data via LDM, the hostname and IP address of your LDM server is what should be specified here. If you will be using FTP, OPeNDAP or the Text/XML Viewer, enter the name and address of the machine from which you will be logging on to the MADIS FTP or Web Services servers. If you don't know your IP or have a rotating IP, please enter that information. If you want to specify multiple machines, please list them in the "Remarks" section below.
