Brian, As Robb mentioned, the LDM will create its own directories, as will dcgrib which I wrote at unidata. Dchrly and dcuair are decoders written primarily at NCEP and require the directory to be created first. Since the LDM just files all of the text files for NWX, all of those directories will be created automatically.
