Presentation Transcript

  1. Fluorescence Line Height (FLH) and Fluorescence Quantum Yield (FQY)

  2. Fluorescence Line Height (FLH) • Histograms of individual monthly L3 composites, 7/2002-2/2010 (black dotted lines) • Mean of individual distributions = distribution of all data pooled together (red line) • Distribution of “deep water” data nearly identical to all data (small differences at high end) • Shallow water distribution shifted towards higher values (as expected)

  3. Fluorescence Quantum Yield (FQY) • Histograms of individual monthly L3 composites, 1/2003-12/2007 (black dotted lines) • Mean of individual distributions = distribution of all data pooled together (red line) • Distribution of data somewhat independent of depth. In fact, median “deep water” value is slightly higher than “shallow”

  4. FLH Percentiles (units of mW cm-2mm-1 sr-1) - NOMAD FLH (N=1143) was calculated assuming Lw(748)=0;

  5. FQY Percentiles (unitless) * this is fsat as in Behrenfeld et al. (2009) # using R2009.1 MODIS data

  6. Particulate backscattering (bbp)

  7. - Distribution of individual datasets from OSU and UCSB Solid – GSM Dotted – QAA Blue – in situ

  8. Distribution of overall in situ dataset and satellite-retrieved bbp • Satellite bbp is from GSM and QAA and has also been • evaluated for shallow v. deep water Solid – GSM Dotted – QAA Blue – in situ

  9. Percentiles (units of m-1) *wrt in situ data, "shallow" refers to the PnB dataset, while "Deep" reflects the OSU dataset. Otherwise they refer to depths <100m and >1000m, respectively

  10. Percentile ranges • 1%, 5%, 10%, 50%, 90%, 95%, 99% • Mean of percentile ranges of individual monthly distributions = percentile ranges of mean distribution

  11. Particulate backscattering (bbp443) • Histograms of individual monthly L3 composites (from GSM), 7/2002-2/2010 (black dotted lines) • Mean of individual distributions = distribution of all data pooled together (red line - GSM; cyan line - QAA) • Percentile ranges • 1%, 5%, 10%, 50%, 90%, 95%, 99% • Mean of percentile ranges of individual monthly distributions = percentile ranges of mean distribution
