So, if we install McIDAS-XCD >version (7.5) which will be fed from the LDM which is connected to the IDD, >will we continue to get MDXX and image files? Yes. In fact, the XCD will produce MDXX files that have _lots_ more stations than the ones you are receiving in the Unidata-Wisconsin datastream. Not only will they have more information, there will be more types (if you decide that you want them) as well. Here is the list of MDXX files that we are currently producing on our LDM ingest machine using either XCD or ldm-mcidas decoders: MD file type Decoder source Scope -----------------+---------------+------- SAO/METAR XCD global Mand. Level RAOB XCD global Sig.

XCD stands for X Conventional Decoders. This is a package that SSEC provides separately. We, on the other hand, have bundled XCD with McIDAS for several years. >Mr. Dong (the cc) is the >student systems administrator and Dr. Bob Kahn (the other cc) is the >Science Division Computing Admninistrator; they are going to make the >McIDAS-XCD installation. In McIDAS-X, building the XCD decoders is very simple. Instead of running 'make' or 'make mcx' one runs 'make all'. The installation is equally simple: instead of running 'install mcx' you simply run 'install all'. >Bob is on the waiting list for the LDM workshop >this summer and I also encouraged him to sign up for the McIDAS >workshop which follows (even though I'm to attend). Currently, all of our workshops are full (16), so he would go on the waiting list for McIDAS as well. >With the workshop >knowledge and Unidata coaching, Bob and Mr. Dong should beable to >successfully update our important McIDAS installation. The installation and setup should take no more than an hour. There are a number of steps involved, but each is very simple. The online documentation for McIDAS-X,-XCD (http://www.unidata.ucar.edu/packages/mcidas/mcx) gives a step-by-step method for building/installing/configuring MCIDAS-X and McIDAS-XCD. We are here to help those who desire it. >Sincerely, I think that it would be a smart move for someone there to do the XCD installation and configuration before anyone comes out to attend the workshops. This way he would have ready questions if there were steps that did not make sense. >Prof. Ward Hindman >
