The MACC Reanalysis production run  (experiment fbov) was started on 2010-03-17 for the analysis cycle 20021201. The month of December 2002 was used a spin-up and will not be part of the official output of the Reanalysis. The first official cycle, 20030101, was started on 2010-03-24. Main features are:

•  24 h long forecast at 00
• IFS cycle 36R1
• branch: stj_CY36R1_MACC_Reanalysis
• model resolution T255L60; CTM resolution 1.125 degrees x 1.125 degrees, L60
• Blacklist: ec:/stj/MACC/black_ds_maccrea_36r1, ec:/stj/MACC/black_mm_macc_reanalysis_CY36R1, and ec:/std/blacklist/black_ex_macc_nrt_36r1
• analysis resolution T159/T95, using 12h 4D-Var and VarBC
• time period 20030101 -20101231
• monitoring plots in /gpfs/scratchrd/ecgems/fbov/obtime/obtime_Retrieved_Gases
• obstat statistics plots in /ws/scratch/rd/ecgems/ps/

• The MOZART CTM (MACC V9) differs in the following points from the version used in the GEMS reanalysis (EXPVER=f026):
  
  • Higher horizontal resolution
  • New anthropogenic and biogenic emissions: MACC D-EMIS (RETRO in GEMS)
  • New fire emissions: GFEDv3/FRP (GFEDv2 in GEMS)
  • Time resolution of fire emissions: daily (8-day in GEMS)
  • Online NOx lightning emissions are slightly reduced
  • Slightly different tracer initialization at the start of the reanalysis

Changes introduced during production affecting the quality of the products are:

real date	exp date	description of change
20100324	2003010512	Added apak@reo3_body and obs_ak_error@errstat to ODBCMP.ddl file
20100324	2003010512	add archiving of 18 UTC mozart start file in archivectm
20100513	2003102200	Bugfix for Mopitt averaging kernel
20100519	2003112600	Include pressure level aerosol in archiving
20100519	2003112600	Include archiving of SCIAMACHY CH4 retrieval error in ODB
20100522	2003121200	Failed in first ifstraj because of MIPAS data. Removed MIPAS data and reran.
20100524	2003121512	Failed in first ifstraj because of MIPAS data. Removed MIPAS data and reran.
20100604	2004012800	Bug fix in MOPITT AK observation operator AD/TL
20100712	2004082712	Found bug in CH4 background statistics, which gave unrealistic high increments around model level 8. Background statistics file corrected (ec:/stj/MACC/Wavelet/wavelet_GEMS_CY36R1_T159_L60.cv) and CH4  level 1 - 20 in short model forecast reset to values from experiment f68c.
20100805	2005011800	MOZART-3 re-compilation with O. Stein's bugfix in the biomass burning emission routine.  The bug caused a shift in the date of the BB data by one day.
20100915	2005062100	Changed Obstream from DA to DCDA (check impact on previous year!)
20100927	20050081900	obstat_reo3 failed because of very high value in observation error of SCIAMACHY CO. Removed SCIAMACHY CO from fetchobs and reran cycle.
20101004	2005092812	Thinning for SCIA GO3 and O3 and MOPITT CO increased to 1deg. Now all datasets are thinned consistently. Change in mklinks to get thin_macc file.
20110202	2007060500	Introduce monitoring of IASI
20110207	2007070400	Activate IASI
20110217	2007082212	Problem with archiving of fbov to MARS. 12UTC and 18UTC have been temporarily stored elsewhere to enable continuation of experiment.
20110221	2007091100	Change path for SCIA NO2 data, to pick up V1.1 from /oparch/gems/sciamachy/knmi_no2/1p1/tropo_col/bufr_ext.  From 30030101-20070630 v1.04 was used, but no data available for that version after 20070630.
20110316	2008010100	Use OMI offline O3 data instead of NRT data. OMI O3 NRT data were used  from 2007032100-2007123118, but have larger departures and stdv of departures than the offline data used before 2007032100.
20110317	2008010100	Turn off varbc for MLS GO3 and O3 to reduce drift in tropospheric ozone values. Change to NAMVARBC_TO3 in ifstraj and ifsmin.
20110404	2008031500	Introduce IASI CO retrievals (with AKs) for passive montitoring. The plan is to use the data actively from 20080401 if they look ok. We will use varbc for IASI CO and MOPITT as anchor.
20110422	2008061512	fetchobs got stuck because of bad ecfs file  with OMI HCHO data for 2008061518. Removed data for the cycle.
20110426	2008070400	fetchobs got stuck because of bad ecfs file with SCIAMACHY HCHO data for 2008070406. Removed data for the 0z cycle.
20110428	2008071112	Minimization failure in 2nd ifsmin and subsequent failure of final ifstraj because of IASI radiance data. Removed IASI data for this cycle and reran 12z analysis.
20110503	20080800800	Changed IASI RTTOV file and used channel list to default from ECMWF operations, i.e., no variable CO2 and CH4. This will hopefully solve the minimization problem.
20110518	2008102400	Important bug fix to input of RTTOV. It solves the spurious SO2 and HCHO increments, but will probably also affect the other tracers, most likely CO2 and CH4. Parallel experiment has been started to test this.
	2009010100	Change emissions from GFED to gfasv1.
20110706	2009042600	Bug fix in grg_ak_op.F90 for IASI CO observation operator
20111017	2010110900	Problem with super-obbing script in CY66R1; not compatible with more than 1 SSMIS instrument. LSSMIS set to FLASE to remove all SMMIS observations.

 

Blacklist changes:

real date	expdate	description of change
20100317	20021201	Start with prepared blacklist
20110404	2008031512	Change blacklist to blacklist IASI CO before 20080401. Ds blacklist file is now ec:/std/blacklist/black_ds_maccrea_36r1. Old blacklist backed up as ec:/std/blacklist/black_ds_maccrea_36r1_before_20080315.
20110519	2008103012	Blacklist IASI CO data because their assimilation leads to lower CO columns and worse agreement with independent observations. Old blacklist backed up as ec:/std/blacklist/black_ds_maccrea_36r1_before_2008103012.
20110613	1009010100	Reactivate IASI CO. Blacklist IASI CO polewards of 70 deg. Old blacklist backed up as ec:/std/blacklist/black_ds_maccrea_36r1_before_20090101.
