Eric, Your data is in the correct format for dcuair, however you need to provide bulletin delimeters to tell the decoder where the product starts and stops. This is the way the decoder finds products in the realtime data stream. You can format your data like: ZCZC F30MANF30 74646 TTAA 63001 74646 99970 32860 18023 00036 ///// ///// 92735 28057 18032 85482 21832 20533 70142 11475 25522 50583 09583 25030 40752 21563 24540 30957 38164 25042 25080 467// 22534 20227 503// 23527 15413 575// 24539 88109 677// 26038 77999 F30SGLF30 74646 TTBB 6300/ 74646 00970 32860 11862 22430 22800 18856 33747 16275 44629 03270 55612 01675 66560 03960 77536 05583 88516 08169 99514 08381 11513 08565 22509 08384 33476 10974 44396 22162 55338 31962 66283 405// 77242 481// 88221 469// 99182 533// 11166 521// 22140 605// PPBB 63000 74646 90012 18023 18023 18031 90346 18532 19534 22031 90789 23028 24024 24520 91124 26023 25523 25024 916// 25021 92025 25032 24036 24540 93013 26040 26042 23544 93457 22542 22538 23028 938// 21529 9423/ 23524 22530 NNNN The ZCZC string is the the start of product delimeter, and the NNNN is the end of product delimeter. To decode with dcuair, you need to use "-c" in front of the dattim, which looks like: dcuair -d - -c 040613/0000 raob2.gem < raob2.txt Steve Chiswell Unidata User Support >From: "Eric Nguyen" <address@hidden> >Organization: UCAR/Unidata >Keywords: 200501260055.j0Q0tEv2015836 >I'm trying to make a gempak sounding file using one sounding so that I can >plot it.
