To anyone who wants to access or has been accessing the Operational
four-per-day Meso Eta 12-km AWIPS grid (#218) in GRIB from
ftp.ncep.noaa.gov/pub/emc/eta12.tHHz (HH=00,06,12,18), please note
that these files are now available at the new NCEP ftp server at 

ftpprd.ncep.noaa.gov/pub/data/nccf/com/eta/prod/ 

in directories/files named eta.yyyymmdd/eta.thhz.awip12ff.tm00,
where yyyy=year, mm=month, dd=day, hh=cycle, ff=forecast hour.

As of 12Z 25 March 2002 these files will no longer be available 
at the ftp.ncep.noaa.gov/pub/emc location.

Additional gridded representations of the 12 km Meso Eta analyses
and forecasts are also available at this site:
files named              contain 
eta.thhz.awip32ff.tm00   full N.Am domain 32 km grid #221
eta.thhz.awip3dff.tm00   extended CONUS 40 km grid #212
eta.thhz.awiphiff.tm00   eastern Pacific 0.4 degree lat-long
eta.thhz.awp211ff.tm00   extended CONUS 80 km grid #211
eta.thhz.awp237ff.tm00   Puerto Rico grid #237 32 km
eta.thhz.egrid3dff.tm00  computational Meso Eta grid on eta levels
eta.thhz.egridsfff.tm00  computational Meso Eta grid surface variables
eta.thhz.grbgrdff.tm00   N. Am. domain 83km NGM look-alike grid #104

in directories MT.eta_CY.hh/RD.yyyymmdd/PT.grid_DF.gr1
where yyyy=year, mm=month, dd=day, hh=cycle
Hourly model forecast soundings are available in BUFR 
in directories MT.eta_CY.hh/RD.yyyymmdd/PT.sndn_DF.buf
