Hi Dave, Have a few minutes during the lunch break in the AWIPS-II training... re: > Well one of the things I tried doing was compiling the 2012 decoders, > failed. Do you have binaries that are not yet up on the site because all I > saw was the 2008 binaries. Also, so does it appear I properly compiled > mcidas except for the decoders. I assume when you say decoders you mean ldm-mcidas decoders. This package is not part of McIDAS, and, quite frankly, only two of the decoders are needed for decoding: proftomd and lgt2md (which replaced nldn2md). McIDAS can use the UNIWISC and NIMAGE imagery directly -- it knows how to uncompress the images on the fly. GEMPAK also knows how to use the images directly. The only reason to uncompress ("decode") the images is if one wants to use them in other applications (e.g., WXP?? I don't know about WXP's capabilities in using satellite imagery much less if Dan Vietor ever added the capability to use the compressed UNIWISC and NIMAGE images directly). re: I see a bunch of dc* files within the > /home/ldm/decoders is that decoders from mcidas or something else that I > don't seem to know about.

Decoder files that begin with 'dc' are GEMPAK decoders, not McIDAS or ldm-mcidas. re: > I just got the new weather with LDM up and running, still need to add in a > scour cronjob but I think I got everything set for mcidas to be installed on > the new weather. I may try to tackle that on my own, but still need to know > how to compile the 2012 decoders. Gil Sebenste said that there have been > significant updates since the 2008 binaries been released. I'm on 64-bit > also. Actually Gilbert is a bit off as far as the ldm-mcidas decoders go -- they are largely unchanged. The biggest difference is the availability of the lightning decoder 'lgt2md' which can handle NLDN and USPLN lightning data. Please forgive me if you answered the following in a previous email: - in what account are you trying to build the ldm-mcidas v2012 decoders? - are the new weather and climate both running the same OS and compilers? If yes, the ldm-mcidas decoders only have to be built on one of the machines.
