Hi, Included in attachment two files bridge/mt/mtrmks.f (modified) and bridge/mt/mtcncltp.f (added). I modified accordingly the Makefile to add mtcncltp.o in the objects. I found all the required docs for coding of surface obs in http://www.msc-smc.ec.gc.ca/msb/manuals/manobs/html/PDFMenu_e.cfm For the RMK coding pratices in METARs, look for: http://www.msc-smc.ec.gc.ca/msb/manuals/manobs/PDF/English/chap20_pg11to18_e.pdf page 8 in PDF file. http://www.msc-smc.ec.gc.ca/msb/manuals/manobs/PDF/English/chap20_appendixii_e.pdf http://www.msc-smc.ec.gc.ca/msb/manuals/manobs/PDF/English/chap10_pg21to40_e.pdf page 4 in PDF file (note that if opacity is zero, it is reported in METAR RMK as CI0 by example). Also, http://www.msc-smc.ec.gc.ca/msb/manuals_e.cfm is a list of manuals on observations and coding pratices for TAF, CLIMAT, etc. Christian Page UQAM On Thu, 6 Sep 2001, Unidata Support wrote: > > Christian, > > I would be happy to look at your changes. > > I try not to make any changes that I would have to continually > update when I get new releases of GEMPAK from NCEP.
