1. Ocean Optics Protocols for Satellite Ocean Color Sensor Validation: Planning for Revision 3 James L. Mueller SDSU CHORS SIMBIOS Science Team Working Group 7 NASA GSFC 31 January 2001

2. Ocean Optics Protocols: Revision 3 Schedule • 31 Jan. 2001: Revise Table of Contents to retain only NEW CHAPTERS for which authors are committed. Also identify changes planned to existing chapters and responsible authors/co-authors. • 15-21 Feb. 2001: Clark and Mueller meet in Hawaii to prepare initial draft of Buoy Radiometry Array chapter. • 30 Jun. 2001: Drafts of Revisions/Updates and of New Chapters due to Mueller – Materials for which drafts are not in hand by this date will be deferred to Rev. 4 in 2002. • 1 Oct. 2001: Final Draft of Rev. 3 to GSFC • 1 Dec. 2001: Publication of Rev. 3

6. Ocean Optics Protocols: Tables of Contents (cont’d 4 of 4)

7. Chapter 8 : Overview of Measurement and Data Analysis Protocols (Mueller) Chapter 3: Instrument Specifications, Characterization and Calibration Overview (Mueller) • Update Specifications, especially for IOP instruments • Overview significant changes to chapters 5-7 (if any) • If one or more new IOP chapters are added to Rev. 3, overview their contents and replace the material in Sect. 3.7 (Rev. 2) • Overview significant changes to Rev. 3 chapters 9-14. • Abstracts of new chapters on Radiometric Arrays on Buoys (12) and Normalized Water-Leaving Radiance (15), and of any other new chapters.

8. Chapter (10): Radiometric Arrays on Buoys: Measurement and Data Analysis Protocols. (Clark, Mueller, tbd..) • Clark and Mueller produce first draft based on MOBY protocols for radiometric measurements and data analysis (15-21 Feb. in Hawaii) • Initial draft will be circulated to potentially interested co-authors (Chavez, Dickey, Lewis, McLean, others tbd) for suggested additions, modifications, etc. Those responding by 30 June 2001 will be included as co-authors. • Bio-optical measurement protocols (Chl fluorometry, IOP’s, etc) on moored and drifting buoys will comprise a separate chapter

9. Chapter 10(11): Above-Water Radiance and Remote Sensing Reflectance Measurement and Data Analysis Protocols • Update to reflect recent progress (Hooker, Zibordi, Morel, etc.) • Include and emphasize methods and criteria for filtering measurements to remove glint, foam, and other noisy data from measurement records. In a slightly broader context, the protocols should address quality control and methods for rejecting measurement sets of overall poor quality.

10. Chapter (13): Normalized Water-Leaving Radiance and Remote Sensing Reflectance: Bidirectional Reflectance and Other Factors (Morel, Mueller, others) • Expand on and update material in Sect. 8.3 of Rev. 2. • Emphasize importance of scattering phase function, and outline procedures which an investigator must use to compute BRDF corrections using new phase functions (e.g. in Case-2 waters). • Provide physics background (link to IOP’s, importance of scattering phase function, etc.).

11. Chapter 13(17): HPLC Phytoplankton Pigments: Sampling, Laboratory Methods and Quality Assurance Procedures (Bidegare, Trees and van Heukelem) • Update as necessary to appropriately incorporate recently published van Heukelem, et al. methods.

12. Other Possibly Significant Modifications to Existing Rev. 2 Protocol Chapters • Ch. 4: IOP specifications are probably outdated. • Ch. 5: Consider including protocols for solar-based calibrations. Requires careful consideration of choice of extraterrestrial flux spectrum. • Ch. 5: Spectralon plaque uncertainties • Ch. 5: Protocols for hyperspectral monochromator based radiometers might well be strengthened. • Ch. 5 and 6: Redundancies? • Ch. 15(24) & App. B: Update to reflect current SeaBASS protocols.

13. Possible New Chapters, if Lead Authors and Co-authors Volunteer to write them (slide 1 of 2) • : In Situ Absorption and Beam Attenuation Meter Calibration (If no volunteers, will be included in Rev. 4 in 2002) • : Scattering Meter Calibration (If no voluteers, will be included in Rev. 5 in 2003, following ONR sponsored workshop planned for late 2002). • Ch. 15: Airborne Radiometric Measurement and Data Analysis Protocols (Harding? Others. Will defer to Rev. 4 or 5 otherwise).

14. Possible New Chapters, if Lead Authors and Co-authors Volunteer to write them (slide 2 of 2) • Ch. (15): LIDAR Aerosol Profile Measurements and Data Analysis Protocols. (If recommended and authors identified by WG5 – else defer for future revision) • Ch. : In Situ Absorption and Beam Attenuation Measurement and Data Analysis Protocols (same as Ch. 8) • Ch. : Scattering Measurement and Data Analysis Protocols (Same as Ch. 9). • Ch. 19: Bio-Optical Arrays on Moored and Drifting Buoys: Measurement and Data Analysis Protocols (Will discuss with F. Chavez, T. Dickey and others in Feb 01 to decide whether to include in 3 or defer to Rev. 4)
