Fields (talk) 11:12, 14 September 2015 (PDT) got reprocessed aqua vgpm npp data from Dr O'Malley. "A result of the r2014 reprocessing was a switch to the new default chlor variable. I have also opted to go back to using the 11-micron daytime SST data rather than the 4-micron. While the cloud penetration is worse, the high latitude coverage matches up with the chlor data for all seasons. Given the increased emphasis on high latitude data, this seemed like a good time to make the switch. Also took the opportunity to tweak the gap fill algorithm on how it covers high latitude values (it now goes to the max latitude of the input chlor data and no further for any 8day period). "

Fields (talk) 12:34, 15 July 2015 (PDT) updated merged operational chlor_a with R2014 Aqua. New arrays were included, chlor_a_err and chlSAM. chlor_a_err is the error, based on "fuzzy" membership to optical water types (see A class-based approach to characterizing and mapping the uncertainty of the MODIS ocean chlorophyll product, Moore et. al. 2009 Remote Sensing of Environment Volume 113, Issue 11, 16 November 2009, Pages 2424–2430) . chlSAM stores chlor_a from the individual sensors (in SeaWiFS, Aqua, Meris order).

Fields 22:20, 9 May 2011 (UTC) replaced Aqua and Merged with Version 6. This is still R2009 Aqua, but uses 6 bands. Also added Aqua4km products. Old 5 bands stuff was relocated to AquaV5 and MergedV5.

• 2011-04-11 I neglected to note that we are transitioning from version 5 to 6.

Version 5, associated with the R2009.1 reprocessing effort (http://oceancolor.gsfc.nasa.gov/forum/oceancolor/board_show.pl?bid=27). Version 6 refers to SeaWiFS R2010.1 (http://oceancolor.gsfc.nasa.gov/forum/oceancolor/topic_show.pl?pid=15555;hl=R2010#pid15555) with the 670 band included, so that 6 wavelengths rather than five were used. For the Merged data, V5 is composed of V5 Aqua and V6 SeaWiFS. We have been waiting for word about what part of the Aqua mission will be reprocessed. When there is version 6 Aqua products they will from 6 bands. V6 Merged will be both V6 Aqua and V6 SeaWiFS. V6 Aqua will likely only differ from V5 after 2007, but will incorporate a additional 6th band (667nm).

• 2011-01-25 Removing Mar-Sep 2010 modis-based vgpm NPP. There was a problem with the aqua sst4 used. Dr O'Malley is reproducing the NPP with the corrected Aqua sst4 input.

• 2011-01-21 R2010 8-day SeaWiFS CBPM2 replaced with an improved product. Robert O'Malley added "a trap on the maximum growth rate" and some NPP gap-filling to the process.

• 2010-12-22 R2010 CBPM2 added. Note CBPM will no longer be produced. Here after NPP produced after 2010 will be the spectral variety and the 2 will be dropped from the name.

note there is an R2010 area. It was waiting for Aqua and Merged products to be made public, but that might be a couple more months.

• actual link to CbPM2 model results added. [Sorry]

• 2010-10-26 CBPM2 NPP model results added.

• 2010-10-18 replaced NPP with new data derived after the R2009.1 reprocessing.

• 2010-09-17 add composite data GSMbin added. Like the daily GSMbin counterpart, except GSMcovMask replaced with the number of pixels composited per bin. The confidence intervals (GSMchl_sig, GSMbbp_sig, GSMacdm_sig) for composite data were also added (actually back in July). These were calculated from composite_sig=sqrt(sum(daily_sig.^-2))

• 2010-08-16 all products (Aqua, SeaWiFS, Merged) have been were reprocessed in June using R2009. Today those were swapped in. The new data have the version "5", in the file name.

• 2009-10-23 an issue has been discovered with the NIR water-leaving radiance model and iteration process as employed in the SeaWiFS 2009.0 reprocessing. "...we know it will have some effect on coastal retrievals, so we anticipate a 2009.1 reprocessing of SeaWiFS in the near future.

• Orbview 2 has been in Safe Haven since the end of August 2009. No SeaWiFS data have been available.

• site updated 12 Oct 2009: new SeaWiFS R2009 was inverted to make new SeaWiFS GSM products. Processing version number incremented to 5.

• Site update 9 Jun 2009: NPP product family page and links to data added.

• SeaWiFS has been in safe haven since 4/23/2009 (day 113). It is not collecting data, so there will be a gap in SeaWiFS and Merged products. 12:34, 26 May 2009 (PDT)

• Site updates 25 May 2009 -- some features not yet implemented.

• Note on missing data (22 Apr 2009)
