News:
I've reprocessed the BBOP MicroPro data with the calibrations listed below - as specified in the timeline.
I then compared the newly reprocessed profiles (where different calibration files were used) with the former data.

BBOP RE-PROCESSING RESULTS: a comparison of the data - REPROCESSED/ORIGINAL (2009 - 2010)

UV channels - ED

visible channels - ED

BBOP CALIBRATIONS: a closer look at the changes that have occurred with the MicroPro (2008 - 2011)

DATA EDITS AND SUBMISSIONS
- The sample times for all the MicroPro data have been edited. All times are GMT.
- All MicroPro data have been RE-submitted to SeaBASS to ensure correct sample times. Jermey has been notified
- PAR values have been calculated from all in-water SPMR & MicroPro irradiance profile data 18.10.2012
- I've asked for a Microsoft operating system to be installed - along with VMware Fusion 02.10.2012
- I've found the "underway" irradiance data associated with the MER.
- I've extracted (and formatted) these Es data and have calculated daily PAR values based on the sampling interval of 1.4 seconds.
- These daily PAR values are now available on-line: ftp://ftp.eri.ucsb.edu/pub/org/oceancolor/BBOP/BBOP_PAR/BBOP_daily_PAR_1992_2011.txt

Global Matchups (In-Situ Data + Remotely Sensed Data Products)
- WEBPAGE: http://www.icess.ucsb.edu/~dcourt/MATCHUPS/

MEaSUREs
- Plan to build some web-tools per Stéphane's needs

Current Projects:

Re-organization of the BBOP database
Purpose:
- To increase the performance of the (in-situ) matchups
Methods:
- Imported all pigment measurements from SeaBASS
- Organized all radiometric data (MER, SPMR, & MicrPro)
- Organized all absorption data (ag, ad, ap & aph)
- Cross-referencing all measurements with BATS log sheets
Issues:
- The chlorophyll values in the original database were incorrect. The chlorophyll values were taken from the IOP bottle-files that had been submitted to SeaBASS. These were labeled as "chl_a", which is defined by SeaBASS as an HPLC product. However, these are Flourometric measurements. At some point, a script needs to be written to re-format these files and a they must then be re-submitted to SeaBASS.
- Many of the sample times are incorrect. This creates inaccuracies when trying to match-up the different measurements. Most of the problems are a result of submitting the data in local (Bermuda) time rather than GMT - as required by SeaBASS. Other issues exist as a result of the technician's computer clock being incorrectly set - sometimes by an order of years. Again, these data will ultimately have to edited and re-submitted to SeaBASS.
