==Files to be updated== | ==GSI Updates== | ||
* | ===Files to be updated/In Progress=== | ||
* | * GSI_GridComp.rc.tmpl (WM) | ||
* | **Initial version available on discover: | ||
* gsi.rc.tmpl | ***/gpfsm/dnb31/wrmccart/merra2/gsi/GSI_GridComp.rc.tmpl.merra2 | ||
* GSI_GridComp.rc.tmpl | **Issues/Questions: | ||
***airs/mhs .blk suffix & consistency w/ obsys.rc | |||
***Which data stream for EOS/Aqua AMSU-A | |||
***TMI rainrate bufr: separate ocean/land sources or combined file? | |||
***SSMI rain rates - unsure if we assimilated all SSMI's in MERRA | |||
***Ensure prepbufr configured correctly | |||
***Needs file structure for AVHRR winds - will need to be consistent w/ obsys.rc | |||
***Entries needed for MLS - T & O3? | |||
***Entry (entries?) needed for TOMS? | |||
***Not updated for cbkg != NONE | |||
* gsi.rc.tmpl (WM) | |||
**Initial version available on discover at: | |||
***/gpfsm/dnb31/wrmccart/merra2/gsi/gsi.rc.tmpl.merra2 | |||
**Issues/Questions: | |||
***All changes above w/ GSI_GridComp.rc.tmpl need to be consistent with and probably to this file | |||
***Reorganized based on Obs type (like GSI_GridComp.rc.tmpl) to ensure dvals/dthins are consistent | |||
***Ozone not organized - defer to Kris/Larry to tidy this up/make dthin&dvals consistent - '''DONE!''' | |||
***Single FOV GOES Sounder only exists from 2007-onward. GOES-08,10 need only sndr_gXX entry, GOES-13,14,15 need only sndrDN_gXX (N=1,4) entries, GOES-11,12 need both | |||
***GOES-14 included w/ numbers fudged from GOES-13 in case future implementation is desired | |||
* all *.arc | * all *.arc | ||
* satbang/satbias restart | * obsys.rc (DM: $NOBACKUP/merra2/run/obsys.rc)) | ||
* | **GPS Startdate need to be confirmed/adjusted. We have data that preceeds the obsys.rc start date | ||
* sac.nl.tmpl | **MetOp-A observations need to be adjusted. | ||
***IASI files start rougly Sept 2008, but the AMSUA/MHS/HIRS streams may start earlier | |||
* update sat-db: | |||
**ozone - as soon as TOMS data are moved to the proper place - edit obsys.rc (Kris) | |||
*** edit ozinfo-db 'active.tbl' to facilitate a switch from SBUV to MLS O3 in 2004 (Kris) - '''DONE''', file sent to RT | |||
**sat | |||
*** GOES Sounders need to be consistent w/ end of 5x5 prep stream (''gXX_prep'' entries in gsi.rc) and 1x1 (''gXX'' entries) | |||
* update conv-db (presently being considered to control conventional obs)-added to tag (JG), will be used as additional tool to stream obs (diverting METEOSAT * AMV's , ERS data for Andrew huricane etc) (DM) | |||
===Files Updated/hopefully completed=== | |||
* gmao_global_satinfo.rc (WM) '''DONE''' | |||
** Template for use w/ satinfo.db: /gpfsm/dnb31/wrmccart/merra2/gsi/gmao_global_satinfo.rc.merra2 | |||
* gmao_global_scaninfo.rc (WM) '''DONE''' | |||
** Updated at: /gpfsm/dnb31/wrmccart/merra2/gsi/gmao_global_scaninfo.rc.merra2 | |||
* <s>gmao_global_pcpinfo.rc</s> - no update needed | |||
* gmao_global_ozinfo.rc - '''DONE!''' | |||
** Available on discover at: /gpfsm/dnb31/wrmccart/merra2/gsi/gmao_global_ozinfo.rc.merra2 | |||

**Should be acceptable for scout runs. Sources of error values/bias coefficients/etc [https://gmao.gsfc.nasa.gov/intranet/personnel/wmccarty/20130708-MERRA2-satfile-sources.xlsx available here]. | |||
* sac.nl.tmpl '''DONE''' | |||

==Observations to be Acquired and/or Processed== | |||
* SSMI Radiances v7 (YK processing data-in progress, DM-testing) | |||
* SSMI v7 wind speed (processed YK, tested DM) '''DONE!''' | |||
* ERS2 scat. (DM-testing) '''DONE!''' | |||
* AVHRR AMVs | |||
** <s>Issue at hand for recent (post-2010) data stream. Infrastructure developed, but base observations may not actually exist (observations used for development may be from an antiquated algorithm).</s> | |||
*** <s> WM - Awaiting further guidance from D. Santek</s> | |||
*** WM - Will proceed forward - working with Rob to determine best way to acquire data | |||
*** bufr files (2010-Oct2013) DONE (DM) | |||
** prepbufr AVHRR winds(1982-2010) (reprocessing files for 1982-1990 due change in input data, DONE (DM) | |||
* Consolidated prepbufr for 79-97 - ncep2013 (DM) | |||
* GPS - preCOSMIc era ? (DM) (from Jack Woollen:gps data starting in 2002 is from the CHAMP instrument, reprocessed by the Boulder folks. Reprocessed COSMIC starts in around 2006) | |||
* IASI (2008-now) (DONE) | |||
* ASCAT (2009-now) DONE | |||
* GOES 1x1 (2007-now) (Done) | |||
* (Question from Mike B.) VAD data prior 2001? (DM) getting data from Jack Woolen (Rob) | |||
**getting new prepbufr data from J. Woolen. DONE | |||
* AIRCRFT data prior cdas prepbufr (2001) can we get reprocessed data? (DM) yes, DONE | |||
* Preprocessed TOMS data need to be moved to a proper place on archive (Kris & Rob)(DONE) | |||
* Get and process OMI and MLS v2.2 for 2012 - present (Kris). The same for MLS Temperature (Larry C.?) DONE | |||
* Set up automatic processing of new MLS T, MLS O3 and OMI data | |||
* tcvitals files (filling gap for 2005 and get some preop 2004 data?) (DM) -Jack Woolen provided 2000-2006 tcvitals (Rob has access to aquired data) DONE , getting additional data for 1980-1999. | |||
==Issues to address== | |||
* Infrastructure to bring in "spun-up" satbias/satbang files. Specific issues: (WM) | |||
** Restart satbias/satbang files created for scout. Question remaining is how will values be adjusted for full M2 (if at all): | |||
*** satbang coefficients & tlapmean values - spin up from scout diags | |||
*** satbias coefficients - substitute in from "spun-up" scout satbias_rst (some delta-time in the future) | |||
* (Question from Austin) How much of the data currently used as 'passive' do we need? E.g. SBUV N16 has been 'passive' in FP for some time; should it be just turned off in MERRA-2? It's bad data |
