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

real date exp date description of change
20091109 2009110812 Introduced aerosol updates in branch stj_CY36R1_MACC_NRT. This also changes the archiving of AOD slightly.
20091201 2009120100 Fix IFS to CTM feedback bug in MOZART. restart files should be ok now.
20100108 2010010800 Changed default fire emissions from 2003 to 2004
20100330 2010033000 Code changes to monitor MOPITT V4 data passively. MOPITT V4 data included in fetchobs.
20100426 2010042600 Change to GFAS fire emissions
20100512 2010051200 Change for assimilation of GOES-13 AMVs
20100519 2010051900 No IASI CO data available after Eumetsat data format change.
20100520 2010052000 Include aerosol in pressure level archiving
20100623 2010062200 Prereo3 failed because of new NOAA-19 SBUV data. Included NOAA-19 (ID=223) SBUV (ID=624) in prereo3. Data will be monitored passively at first.
20100714 2010071400 Add GOME-2 tropospheric NO2 data in fetchobs to monitor passively.
20100728 2010072700 Screening trajectory failed with Memory kill. Problem likely to be caused by aerosol, but not clear why. Reconfiguration took some time, but new configuration with THREADS increased to 16 worked.
20100801 2010080100 AOD archiving was changed to archive every 3 hours for the whole forecast range (up to 96 hours)
20100817 2010081600 IASI CO data back. Run 20100816 and 20100817 without varqc and fg-check for CO, so that data with high CO over Russia don't get rejected.
20100913 2010091300 Corrected missing archiving of model level cloud fields (introduced in restart at 2010090100)
20101004 2010100400 Thinning for SCIA O3 and GO3 and MOPITT CO increased to 1deg. Now all datasets are thinned consistently. Change in mklinks to get thin_macc file.
20101109 2010110900 Change mklinks to get 3 extra IASI channels (2908, 3050, 3056) for SO2 diagnostics.
20101110 2010110900 Problem with super-obbing script in CY36R1; not compatible with more than 1 SSMIS instrument. LSSMIS set to FALSE to remove all SMMIS observations.
20101216 2010111512 Problem with bad data in operational IASI bufr file. Removed IASI data from for this cycle. For future cycles correction will take place in operational data stream itself.
20101223 20101222, 0z Failure due to presence of MTSAT-2 data (ident=172). Milan introduced a fix in pregeos to filter data out from the bufr files.
20101226 2010122400 Ifstraj failed because of bad data in operational IASI bufr file. Removed IASI data for this cycle.
20101229 2010122812 Ifstraj failed because of bad data in operational IASI bufr file. Removed IASI data for this cycle.
20110107 2011010700 Edited the pregeos script to allow MTSAT winds to enter the assimilation. They were removed in December together with the radiances. Only the radiances caused problems though.
20110113 2011011300 Start monitoring of NRT OMI SO2 (mid troposphere product).
20110207 2011020700 Switched the near-real-time acquisition of MODIS aerosol from Nanuk to LANCE. LANCE products have been acquired from 20110206 onwards. Starting from 2011020700  the experiment will contain MODIS aerosol data from LANCE only.
20110509 2011050900 New version of KNMI SCIAMACHY ozone retrieval (TOSOMI v2).
20110706 2011070600 Bug fix in the IASI CO observation operator
20120222 20120221 MLS instrument offline after suspected Single Event Upset event that shut down the on-board computer at 18:39UTC on Sunday 19th February 2012. The current plan is for the instrument to return to normal science operations around Friday February 24th 2012. No data will be available during this period.
20120301 2012022900 Final trajectory failed because Mozart had archvied output for 29 Feb as 1 March. Files have been copied back to correct date.
20120315 2012031500 NO MLS data. AURA MLS Instrument has encountered an anomaly as of DOY 074 1834z and MLS has been off since 14/03. Due back on 21/03 according to JPL website
20120321
20120305 No MOPITT CO data (passive) because of hot calibration event between 5-16 March.
20120322 2012032200 MLS back. MLS Instrument has been stored to "Nominal" scan mode and it is now back on-line.
MLS Level 2 NRT Data are available again starting from 2012-03-21 18:10.
20120330 20120330 NO IASI CO data between ~14:00 - 21.00 because of problems with LATMOS data server.
20120416 20120408 No Envisat data (e.g. SCIAMACHY, MIPAS) since 8 April after contact with satellite was lost.
20120416 20120423 No IASI CO data. The IASI CO NRT processing will stop Monday, 23 April at 7 UTC because of a power outage. If all goes well, this will only last 48 to 72 hours and data will come back on Wednesday, 25 April.
20120612

20120524-

20120612

Reduced MOPITT CO data numbers (passive) between 20120524-20120612 because bug in MOPITT processing chain led to many (but not all) files being generated with no data inside.
20120612

20120601 -

20120611

No MLS data. Tightening of security on NASA's EOSDIS User Registration System required a password change on 1 June 2012. By mistake this was not applied to the acquisition of MLS ozone until 11 June, and not data were picked up during this period.
20120627 20120627- LANCE-MLS Registered Users: Please expect gaps in the MLS Level 2 NRT data. There has been a resurgence in activity by the existing anomaly on the spacecraft, that Aura has been experiencing for the past couple years. GES DISC team continues to investigate the cause(s) of the gaps to recover as much NRT data as possible.
20120701 20120702 Planned OMI data outage between July 02, 2012 , 1749 UTC and
July 03, 2012, 1749 UTC
20120704 20120703 Bugfix for IASI CO observation errors. The errors had been read as relative error in % and set to max(5%, obserr)  in the BUFR software. They are however given as relative error in the original data files. This meant that prior to today all errors were a factor 100 too small and set to 5%. First observation with proper relative error is for 20120703 13:17:57.
