I think this comes from here:<br>
<br>
On grib1 output from UPP - this is for 10min record, all normal:<br>
<br>
$ wgrib WRFPRS_d01.00_10<br>
1:0:d=17111700:RWMR:kpds5=170:kpds6=109:kpds7=1:TR=10:P1=0:P2=10:TimeU=0:hybrid
lev 1:10min fcst:NAve=0<br>
2:44496:d=17111700:SNMR:kpds5=171:kpds6=109:kpds7=1:TR=10:P1=0:P2=10:TimeU=0:hybrid
lev 1:10min fcst:NAve=0<br>
3:88992:d=17111700:REFC:kpds5=212:kpds6=200:kpds7=0:TR=10:P1=0:P2=10:TimeU=0:atmos
col:10min fcst:NAve=0<br>
...<br>
<br>
however, for 30min record:<br>
<br>
$ wgrib WRFPRS_d01.00_30 <br>
1:0:d=17111700:RWMR:kpds5=170:kpds6=109:kpds7=1:TR=10:P1=0:P2=1:TimeU=14:hybrid
lev 1:30min fcst:NAve=0<br>
2:44496:d=17111700:SNMR:kpds5=171:kpds6=109:kpds7=1:TR=10:P1=0:P2=1:TimeU=14:hybrid
lev 1:30min fcst:NAve=0<br>
3:88992:d=17111700:REFC:kpds5=212:kpds6=200:kpds7=0:TR=10:P1=0:P2=1:TimeU=14:atmos
col:30min fcst:NAve=0<br>
...<br>
<br>
TimeU=14<br>
<br>
<br>
Where this comes from? <br>
<br>
As far as I understand it, UPP follows this time designation for
time units:<br>
<a class="moz-txt-link-freetext" href="http://www.nco.ncep.noaa.gov/pmb/docs/on388/table4.html">http://www.nco.ncep.noaa.gov/pmb/docs/on388/table4.html</a><br>
14 = "Half an hour"<br>
<br>
This is from UPP code that sets it:<br>
<br>
! J. HALLEY GOTWAY, MODIFY HOW THE TIME INFORMATION IS STORED
IN ID(17-20),<br>
! (FCST TIME UNIT, P1, P2, TIME RANGE INDICATOR).<br>
! CHECK IF THE NUMBER OF FORECAST MINUTES IS ZERO FOR HOURS OR
NON-ZERO FOR<br>
! OFF-HOUR FORECASTS. FOR OFF-HOUR FORECASTS, CHECK IF THE
TOTAL NUMBER<br>
! OF MINUTES IS DIVISIBLE BY 30, 15, OR NEITHER, AND USE THE
APPROPRIATE<br>
! FCST TIME UNIT VALUE. FOR ANY FIELD OTHER THAN AN
INSTANTANEOUS FIELD,<br>
! ASSUME ID(18-20), ARE PASSED IN CORRECTLY.<br>
<br>
IF(IFMIN .GE. 1)THEN<br>
! ID(17) = 0<br>
! COMPUTE THE TOTAL FORECAST MINUTES.<br>
TOTMIN=IFHR*60+IFMIN<br>
<br>
! CHECK FOR 1/2 HOURLY INCREMENTS.<br>
IF (MOD(TOTMIN, 30) == 0) THEN<br>
ID(17) = 14<br>
DIV = 30<br>
! CHECK FOR 1/4 HOURLY INCREMENTS.<br>
ELSEIF (MOD(TOTMIN, 15) == 0) THEN<br>
ID(17) = 13<br>
DIV = 15<br>
! OTHERWISE, USE MINUTES.<br>
ELSE<br>
ID(17) = 0<br>
DIV = 1<br>
ENDIF<br>
<br>
<br>
Does this look OK to you?<br>
<br>
Thx<br>

I finally found time to dig into this.<br>
<br>
I actually get "undefined time unit 14" from
wgrib2 when trying to handle 30 min records.
That's probably why g2ctl, alt_g2ctl also does
not do the job (throwing this message) and so
on.<br>
<br>
For example, your suggestion #2:<br>
<br>
$ wgrib2 wrfprs_d01.00_30.g2 -if ":30 min fcst:"
-set_ftime "30 min fcst" -fi -grib
wrfprs_d01.00_30.g2.con<br>

I'm having
difficulties
reading sub-hourly
time records from
WRF grib<br>
files in GrADS.<br>
<br>
UPP follows NCEP
code table for
timing grib
records - for 15

codes 13 and 14

instead of simple<br>

<br>
What I get as
result is that I
can read any
sub-hourly record
as long as<br>
it is not 15 or 30
minute record. For
those, I get
undefined grid<br>
instead of data.<br>
<br>
I use this
workflow for
postprocessing:

>(cnvgrib)><br>
grib2
>(g2ctl,gribmap)>
