MERRA2 InputData

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 (1979-1997 reprocessed data, 1997-1998 pulled additional files from CFSRR)
    • 1982-2000 added Vaisala correction (from original files processed by Chris Redder, adpupa_fixvai)
    • exclusion of NPN profiles data (we have separate files for npn profiler from NCAR)
• cdas (2001-present)
  • data from original MERRA

ASCAT (20090301-recent)

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

AVHRR polar winds (1982-recent)

• source: CIMSS
• ascii to prepbufr (code YK,DM)
  • (82-Sep09): ftp://stratus.ssec.wisc.edu/pub/winds/histavhrr/newversion
  • (Oct09-Jun10): ftp://stratus.ssec.wisc.edu/pub/winds/archive
• bufr format (code WC)
  • 20100701 we witch to bufr format for all AMV
  • (Jul10-recent): ftp://stratus.ssec.wisc.edu/pub/winds/archive

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.

ERS scatterometer

• ERS1 (19910805-19960525) lots of short gaps
• ERS2 (20030813-20110329) new version of data
  • The re-processing of ers-2 runs from from 1997-2003. 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
  • For the period from 2003 through the end, we have the fast delivery product (WSC.UWI).

QuikSCAT Data

• data from jpl (19990719-20091122; ms added 2003,2004)

SSMI Wind Speed

  • F14 SSM/I May 1997 Aug 2008
  • F15 SSM/I Dec 1999 present (do not use after Aug 2006 for climate study)
  • F16 SSMIS Oct 2003 present
  • F17 SSMIS Dec 2006 present
  • F18 SSMIS Oct 2009 present

NPN Profiler

• data from NCAR, gaps filled from original Jack Woolen's cdas files
• (19920510-20080731)(exluded from cdas and cdas0)

NO-preQC data

tcvitals

• (1980-present)
• data prior 2006 from Jack Woolen
