* Atlantic anomaly in 79-80 -the same issue in MERRA ([http://merra-reanalysis.blogspot.com/2008/10/known-issue-1-east-atlantic-anomaly.html]) ????  Steve Bloom identified anomalies associated with two stations - 99012 (~ weather ship Lima) in Atlantic off Portugal, and 99018 (~ weather ship Quebec) in the Pacific.

* Fix for blacklisted observations from Singapore station (ID 48698), ADUPA files were processed using code delivered by Meta for original MERRA input (~/Applications/NCEP_Paqc/modify_bufr);formerly blacklisted data were from 7/22/1998 - 02/23/2000 ([https://progress.nccs.nasa.gov/trac/esma/ticket/72])
* The prepbufr files received from NCEP after 12/29/2020 00z had already been processed through their PREVENTS step and thus had the temperatures for surface marine and surface land observations converted to virtual temperature.  The MERRA2 preprocessing carried out the VIRTMP conversion a second time.  A program to scan the input file to determine if the VIRTMP processing had already been done was added to the preprocessing QC, and the MERRA2 run was wound back to 1 June 2021. Note that between 12/29/2020 and 5/31/2021 the screening program would need to be disabled and virtual temperature calculated a second time if one wished to reproduce the MERRA2 results.  Or, just use the already processed prepbufr file from after the prepQC archived from MERRA2 as input instead of redoing the preprocessing.

** operational AVHRR in gdas satwnd files from 20150115 06z onward, from time of GOES hourly wind introduction
** operational AVHRR was intended to be removed from time-windowed satwind BUFR files, but that version of the time-windowing software somehow didn't make it into ops
** operational AVHRR no longer in time-windowed files after 20150520 00z (ops time-windowing software updated to take out EUMETSAT WV winds to reduce data count)

Input Data Information This is a page to keep information about input data (source, processing, gaps and known issues).


Conventional data pre-QC

PREPBUFR

  • RADCOR=HAIMB_HRAD
  • cdas0 (1979-2000)
    • data from Jack Woolen; recieved 2013 (1979-1997 reprocessed data, 1997-1998 pulled additional files from CFSRR)
      • updates to METEOSAT AMV (early reprocessed 82-87) JW
      • updates to ADPSFC (data types 181 and 183 separated before 1998) JW
      • 1982-2000 added Vaisala correction (from original files processed by Chris Redder, adpupa_fixvai)(DM)
      • exclusion of NPN profiles data (we have separate files for npn profiler from UCAR) (DM)
  • cdas (2001-present)
    • data from Jack Woolen for original MERRA
      • Vaisala correction (Chris Redder)
      • NPN profiler excluded until 20080731 (profiler obs file) (except station in Pacific and Europe that have the same kx 223)
  • PAOB data 19790101-20100817
  • SATWND data in prepbufr until 20100701 (after in bufr format file)
  • GMS WV satwinds (KX=250) in prepbufr files are passive (missing obs. error). This is necessary because GMS WV satwinds in prepbufr format do not have information needed to distinguish between cloud-top and deep layer WV winds, and we are not able to turn on only cloud-top winds as we do for the winds from the satwind dump bufr format file.
  • TAMDAR data - passive (quality issues: missing tail numbers, bias) correction of KX
    • in sweeper b5122_m2swp_jan10 run Meta found that few of the aircraft data had missing staion ID: "in our current configuration we can not do anything different for these winds, because they have been misidentified as other aircraft types (kx=130/230 AIREP/PIREP and kx=131/231 AMDAR)"
    • fix code: NCEP_Paqc/modify_bufr/fix_tamdar.f (correction of kx and screen them out)
    • counts in fixed data seems lower then in operational run, probably due to different processing (NCEP ops & in house fix for reanalysis input TAMDAR data)
  • Atlantic anomaly in 79-80 -the same issue in MERRA ([1]) ???? Steve Bloom identified anomalies associated with two stations - 99012 (~ weather ship Lima) in Atlantic off Portugal, and 99018 (~ weather ship Quebec) in the Pacific.
  • Fix for blacklisted observations from Singapore station (ID 48698), ADUPA files were processed using code delivered by Meta for original MERRA input (~/Applications/NCEP_Paqc/modify_bufr);formerly blacklisted data were from 7/22/1998 - 02/23/2000 ([2])
  • The prepbufr files received from NCEP after 12/29/2020 00z had already been processed through their PREVENTS step and thus had the temperatures for surface marine and surface land observations converted to virtual temperature. The MERRA2 preprocessing carried out the VIRTMP conversion a second time. A program to scan the input file to determine if the VIRTMP processing had already been done was added to the preprocessing QC, and the MERRA2 run was wound back to 1 June 2021. Note that between 12/29/2020 and 5/31/2021 the screening program would need to be disabled and virtual temperature calculated a second time if one wished to reproduce the MERRA2 results. Or, just use the already processed prepbufr file from after the prepQC archived from MERRA2 as input instead of redoing the preprocessing.

ASCAT (20080301-recent)

  • from ASCATW (bufr files needs to be processed (~msienkie/ascat/prepdata; historical data were processed by DM (from 20090301), realtime-it will be part of preprocessing)
  • gap in September 2010 was originally filled from ASCATT format by MS)
  • adding data prior 2009 (WM)
  • real-time preprocessing (YK)


AVHRR polar winds (1982-recent)

  • source: CIMSS
  • obs. errors table in prepobs_errtable.global added (copy of modis ir amv's obs errors)
  • ascii to prepbufr (code YK,processed DM)
  • no observation for 12z and 18z between 20091223-10100103
  • bufr format (code WC, processed DM)
  • additional source: NESDIS via NCEP
    • operational AVHRR in gdas satwnd files from 20150115 06z onward, from time of GOES hourly wind introduction
    • operational AVHRR was intended to be removed from time-windowed satwind BUFR files, but that version of the time-windowing software somehow didn't make it into ops
    • operational AVHRR no longer in time-windowed files after 20150520 00z (ops time-windowing software updated to take out EUMETSAT WV winds to reduce data count)

SATWINDS (Atmospheric Motion Vectors)

  • switch from prepbufr to bufr format on Jul1, 2010
  • 1979 GOES - additional AMV from FGGE (First GARP Global Experiment), which ran from Dec. 1978 to Nov. 1979. There should be AMVs from GOES East and West, Meteosat-1, GMS-1, and GOES Indian Ocean. The winds were produced here at UW-Madison, using manually tracking (from Dave Santek,CIMSS).
  • 20130121 - METEOSAT AMV's (kx=243) switch to METEOSAT 10 (id=57)

ERS scatterometer

  • ERS1 (19910805-19960525) lots of short gaps
    • exclude 06z Aug 24, 1992 (hurricane Andrew); in original MERRA this set of winds had negative impact
  • The re-processing of ERS-2 data from 1997-2003.
    • 19970520_00z-20030217_18z
    • The three available formats of the re-processed data are:
      • ERS.ASPS.UWI (re-processed data in UWI format for compatability with the real-time product)
      • ERS.ASPS20.N (re-processed data in ASPS format: nominal resolution 50km)
      • ERS.ASPS20.H (re-processed data in ASPS format: high resolution 25km)
    • We are processing ERS.ASPS20.N. For this data, lets give a filename like: ers2_asps20n.YYYYMMDD.tHHz.bufr
  • ERS2 (20030813-20110329) new version of data
    • For the period from 2003 through the end, we have the fast delivery product (WSC.UWI).

    • 31Mar2009 Todling The following changes made to mimic NCEP choices for 200901 and beyond
      • - off chn all sndr-g12
      • - off chn all sndrD1/D2/D3/D4-g13 (?)
    • 03Aug2013 Todling - add GOES-15 as active
    • 10Sep2013 Sienkiewicz - some updates for GOES sounder
      • 5x5 prepbufr ends 12/4/2007 12z. (Overlaps 1x1 data)
      • turn off sndrdX in early Dec 2007, problem with SAID (see Keyser's Satellite_Historical_Documentation.htm)
      • NCEP dump of 1x1 starts ~2/22/07 00z. g11 mislabeled as g10 until 2007/03/20 18z ; satID values OK in 5x5 data though - so do not use 1x1 prior to 2007/03/20 18z!
      • GOES-10 to GOES-11 transition: 5x5 prepbufr has all 3 types (10,11,12) at 20060621.t18z with g10 before and g11 afterward.
      • GOES-8 to GOES-12 transition: 5x5 prepbufr has all 3 types (8,10,12) at 20030401.t18z with g08 before and g12 afterward.
      • Note: GOES-13 replaces GOES-12 as operational 4/14/2010 18z
      • Note: GOES-15 replaces GOES-11 as operational 12/6/2011 15z
      • Need to check when these data start in the 'goesfv' dumps & when/if we want to turn these on in the database.
    • 29Oct2013 Todling/(per Sienkiewicz) - turn GOES-13 back on from 20090101 on.
    • 20Nov2015 GOES-13 Sounder anomaly - end of GOES-13 Sounder data
    • 3Mar2020 GOES-15 Sounder data ends in operational stream. No sounder on GOES-R (GOES-16, GOES-17 satellites)
