NOAA
Profiler Network (NPN) winds now used in RGL analysis. (Also in
RUC??)
11/05/1997/1200UTC:
VAD winds are now used in the GBL analysis (not yet used in the RGL analysis). NOAA
Profiler Network (NPN) winds are now used in the GBL analysis.
NPN wind profiler reports are QC'duntil the NWS/AirDAT contract is renegotiated. This could be 2-3 weeks. by the new program PROFCQC, in
the GBL only.
02/09/1998/1200UTC:
RGL-3DVAR implementation resulted VAD winds now being used in the RGL analysis.
01/08/1999/1900UTC:
VAD winds are no longer being used in the RGL and GBL analyses due to quality issues.
11/10/1999/1000UTC:
NPN wind profiler reports are now
QC'd by the program PROFCQC in the RGL and RUC networks (as they had
been in the GBL networks).
03/29/2000/1200UTC:
VAD wind reports are now QC'd by the
new program CQCVAD. All reports with a low RMSVE are now again
used in the RGL and GBL analyses.
01/09/2001/1200UTC:
Tropical wind profilers that arrive
disguised as PIBAL reports are now correctly processed as profilers and
are used in the RGL (unlikely any present in domain) and GBL analyses.
09/10/2002/1500UTC:
JMA wind profiler data are now encoded into BUFR tanks b002/xx013 in /dcom.
04/13/2004/1200UTC:
JMA wind profiler and CAP wind
profiler data are added to "proflr" dump - they are not yet written
into PREPBUFR or assimilated in any network.
01/25/2005/1200UTC:
Program PROFCQC, which QC's wind profiler data, has been upgraded. JMA wind profiler data now encoded in the GBL PREPBUFR files (report type 228) but they are not yet assimilated in any
network. CAP
wind profiler data now encoded in the RUC and RGL PREPBUFR
files (report type 227) but they are not yet assimilated in
any
network.
04/28/2006:
Cooperative Agency Profiler (CAP)
data are no longer available via GTS/BUFR due to the NWS no longer
supporting it. There may be a way to get these data from FSL
(GSD) MADIS in netCDF format.
09/15/2008/1500UTC:
Wind profilers coming in in PILOT (PIBAL) bulletins are now
included in the "proflr" dump file and the PREPBUFR file in the RUC
network (report type 229). These data are not assimilated by the
RUC analysis. They will be used by the future (2009)
RapidRefresh system.
10/01/2008:
NOAA Profiler Network (NPN)
wind profiler data (tank b002/xx007 and dump "proflr", used in the
GFS, NAM and RUC analyses), spectral moment data (tank b002/xx010,
not dumped or used by any analyses) and Radio Acoustic Sounding
System (RASS) temperature profile data (tank b002/xx012 and dump
"rassda", used in the RUC analysis, monitored in the GFS and NAM
analyses) obtained from the GTS have been temporarily suspended
for up to 90 days as a result of the need to upgrade these systems to
prevent recently identified IT security threats. The wind profiler
network operates on obsolete equipment that cannot
support necessary IT security methods, and interconnection to
major NWS systems extends the vulnerability to the entire NWS
IT infrastructure. The NPN profiler data (and possible the other types) will be
available in the same BUFR format from an alternate GSD/MADIS feed
within the next few (3-5) weeks.
10/27/2008:
NOAA Profiler Network (NPN) wind
profiler data (tank b002/xx007 and dump "proflr", used in the GFS, NAM
and RUC analyses), spectral moment data (tank b002/xx010, not dumped or
used by any analyses) and Radio Acoustic Sounding System (RASS)
temperature profile data (tank b002/xx012 and dump "rassda", used in
the RUC analysis, monitored in the GFS and NAM analyses) are now again
available, this time from the alternate GSD/MADIS feed. This is
temporary until the primary NWS feed is restored in approximately two
months. (See 10/01/2008 entry for more information.)
11/25/2008/1500UTC:
Multi-Agency Profiler (MAP) wind and
RASS data [previously called Cooperative Agency Profiler (CAP)] are
once again being decoded into tanks b002/xx011 (MAP profiler
winds) and b002/xx012 (MAP RASS, along with NPN RASS), via feed from
GSD MADIS (decoded into BUFR from netCDF format). The MAP winds
are being written into the "proflr" dumps in the NAM/NDAS, GFS/GDAS and
RUC networks. They are included in the PREPBUFR file with report
type 227 in the NAM/NDAS and RUC networks. These are
not monitored or assimilated in any network. The MAP
RASS are being written into the "rassda" dumps and are included in
the PREPBUFR file with report type 126 in the
NAM/NDAS, GFS/GDAS and RUC networks. These are assimilated
in the RUC network and are monitored in the NAM/NDAS and GFS/GDAS
networks.
01/07/1988:
Indian radiosonde (block 42 and 43) mass data are no longer used in the GBL analysis.
06/25/1991/1200UTC:
GBL-SSI implementation resulted in
several changes in data usage in GBL analysis: Significant and
mandatory level data now used. No interpolation of data to
missing levels (RGL analysis still uses special 25 or 50 mb levels with interpolation to missing levels).
Uppermost mandatory pressure level for processing all variables
except moisture changed from 50 to 10 mb. Uppermost mandatory
level below which significant level variables (except moisture) are
processed is 50 mb. Uppermost mandatory pressure level for processing moisture changed from 300 to 250 mb.
02/10/1992/1800UTC:
CLASS wind data (received from
STORM-FEST field experiment) is now used in the RGL analysis.

longer be processed (they they ever became present again) in the RGL
analysis on 02/09/1998/1200UTC.
06/10/1992/1200UTC:
The Complex Quality Control (CQC)
system was implemented (for radiosonde data). It replaced the
"Hydrocheck" program.
08/11/1993/1200UTC:
The uppermost mandatory pressure
level for processing mandatory and significant level data (including
moisture) is changed from 10 mb (mandatory) and 50 mb (significant) and
250 mb (moisture) to 1 mb.
08/28/1995/1200UTC:
Surface mass dropwinsonde data are
no longer used in the GBL analysis (due to quality issues).
10/25/1995/1200UTC:
Indian radiosonde (block 42 and 43) are now used in the GBL analysis.
05/20/1997/1200UTC:
The radiosonde baseline check in
PREPRO has been turned off. The CQC program already performs a
much more sophisticated baseline check.
06/11/1997/1200UTC:
New Gulf Stream dropwinsonde data is
about to become operational. Its specific humidity will not
be used in the RGL or GBL analyses due to quality issues. (Later, on
01/14/1998/1200UTC, the RGL and GBL analyses began using Gulf Stream
dropwinsonde moisture, then even later, on 12/15/1998/1200UTC, the RGL
and GBL analysis again stopped using Gulf Stream dropwinsonde moisture.)
02/09/1998/1200UTC:
RGL-3DVAR implementation resulted in several changes in data usage in RGL analysis: Data
are no longer interpolated to 25 or 50 mb levels (reported mandatory
and significant levels are used directly). Moisture is no longer
interpolated to levels where it is missing. The uppermost
mandatory pressure level for processing mandatory and
significant level data (including moisture) is changed from 10 mb
(mandatory) and 50 mb (significant) and 250 mb (moisture) to 1 mb.
01/25/1999/1200UTC:
USAF dropwinsonde moisture in no longer used in the RGL and GBL analyses.
10/02/2000/1200UTC:
The GBL analysis
began using radiosonde and PIBAL balloon drift (location and
time) information.
06/13/2006/1200UTC:
The RGL analysis (changed to GSI today) is now using radiosonde and PIBAL balloon drift (location and time) information.
08/22/2006/1200UTC:
NOAA (P-3 and Gulf Stream)
dropwinsonde moisture is now used in the GBL analysis (it is still not
used in the GBL analysis, neither analysis uses USAF dropwinsonde
moisture).
12/04/2007/1200UTC:
NOAA (P-3 and Gulf Stream)
dropwinsonde moisture is now used in the RGL analysis (it had
already been used in the GBL analysis). USAF dropwinsonde
moisture is now used in the RGL and GBL analyses.
9/20/1988/1200UTC:
Splash-level dropwinsonde reports are now used in the RGL and GBL analyses.
12/06/1989/1200UTC:
The wind part of splash-level
dropwinsonde reports is no longer processed. Fixed and
moored buoy wind reports with no station pressure are now
processed (on 10/02/1991/1200UTC this was restricted to only PMEL-ATLAS buoys in the tropical Pacific).
01/30/1991/1200UTC:
NMC digitized mean sea-level
pressure bogus data no longer used by GBL analysis. (The GBL and
RGL analyses still use the OPC/NOS mean sea-level pressure point bogus,
usually available in NH only).
06/25/1991/1200UTC:
GBL-SSI implementation resulted in
mass data from land SYNOP stations and mass and wind data from C-MAN
platforms now being used in GBL analysis. Mass land SYNOP
data is already being used in RGL analysis.
01/31/1997/1200UTC:
Mean sea-level pressure bogus (PAOBs
in GBL and OPC/NOC point in the RGL and GBL) are no longer used in the
RGL and GBL analyses.
02/09/1998/1200UTC:
RGL-3DVAR implementation resulted in several changes in data usage in RGL analysis:

(SYNOP) mass and wind reports within the old LFM grid domain and
without pressure are now being used.
01/09/2001/1200UTC:
METAR mass and wind data are now assimilated in the RGL analysis.
01/25/2005/1200UTC:
Mobile synoptic land mass and
wind data used in GBL analyses (not yet used in RGL analysis,
outside of domain anyway).
06/28/2005/1200UTC:
Mesonet mass data are now
assimilated in the RUC analysis (based on "uselist"). METAR
cloud/visibility/weather observations.are now assimilated in the
RGL analysis.

Mesonet wind data are now assimilated in the RGL analysis (based on "uselist").
09/15/2008/1500UTC:
SYNOPTIC (both restricted and unrestricted) surface land data are now included in the "adpsfc" dump file and the PREPBUFR
file in the RUC network (report types 181/281, 183/284). These data are now assimilated by the
RUC analysis. They will also be used by the future (2009) RapidRefresh
system.
09/16/2008/1200UTC:
Roadway data
from numerous mesonet providers (mainly DOT providers) is now
ingested into the applicable /dcom b255 BUFR tanks and
subsequently dumped into the "msonet" dump files and encoded into the
PREPBUFR files in the appropriate networks [dumps in NAM, NDAS, GFS,
GDAS, CDAS, RTMA, RUC and SRUC; PREPBUFR in NAM, NDAS, RTMA, RUC
(upper-air)]. It is not yet used by any NCEP analysis (currently
mesonet data are assimilated only in the NAM, NDAS RUC and RTMA
networks).
11/17/2008/1200UTC:
Mesonet wind data are now assimilated in the RUC analysis (based on "uselist").
12/16/2008/1500UTC:
The RUC analysis now uses mesonet
mass and wind data only from the site in the "msonet" dump file
closest to the analysis time (when a site appears at more than one time
in the dump file).
6/17/2008/1200UTC:
Update to the ingest package.
Radial wind quality control significantly upgraded. New
reflectivity quality control added. Reflectivity Single
Radar Coordinate (SRC) flat-files are now generated for the
(yet-to-be-implemented) radar reflectivity mosaic processing package to
pick up.
6/17/2008:
Nearly 90 of the 135 NEXRAD sites
over the CONUS have now switched from Build 8 to Build 10 software.
We are still unable to ingest these Build 10 sites, so we are
losing ~67% of the Level II (and possibly also Level II.5) radar
data.
09/15/2008/1500UTC:
Level II and
Level II.5 NEXRAD radial wind data are now dumped ("radwnd") in
the RUC network. These data are not assimilated by the RUC
analysis. They will be used by the future (2009)
RapidRefresh system.
09/15/2008:
All 135 NEXRAD sites
over the CONUS have now switched from Build 8 to Build 10 software.
We are now unable to ingest any Level II radial wind and
reflectivity data from these Build 10 sites. Level II.5 and III
radial wind data are not affected.
10/07/2008/1500UTC:
We are now again able to ingest
Level II radial wind and reflectivity data from all 135(?) NEXRAD sites
with the implementation of the "supres" ingest code which reads Build
10 and transforms it back into pseudo-Build 8 before ingesting it into
/dcom. These data are again dumped into "nexrad" files in the NAM
and NDAS networks and are again being assimilated by the NAM/NDAS GSI.
11/17/2008/1200UTC:
The RUC analysis now processes three-dimensional
Level II radar reflectivity mosaic data which produces a latent heat
specification to be used in the model digital filter.
