چکیده
We are grateful to you for your very positive and constructive comments. Following the helpful suggestions from you and another reviewer, we believe our manuscript has been modified significantly. Below are our replies to your comments. RC = Referee’s Comments; AR = Authors’ Response RC 1: Why the SeaWiFS period is limited to 1997-2007 only? Good quality observations are available at least until 2009 and I think the extension of the period could

RC 2: Page 4364, line 25 ff.: Because in the Southern Ocean ocean color data are scarce, it is dangerous to base the analysis on monthly means of satellite data. These can be represented by very few observations especially in wintertime. I therefore recommend to first use the daily level-3 data and calculate from that monthly mean values in case a threshold for a reasonable amount of observatio...

AR 1: As you kindly suggested, the extension of the SeaWiFS period could strengthen our results. However, we have found that sufficient data are unavailable for statistics during January 2008 and December 2009 (i.e., 7 out of 24 month data are only available in the period. In addition, less than 2 daily data are available per month at the maximum). In particular, because SeaWiFS data from Janua...
متن کاملPutting Together the Big Picture: Remote-sensing Observations of Ocean Color SPECIAL ISSUE – JGOFS
Observations of ocean color from space have been part of the U.S. JGOFS strategy for discerning temporal and spatial variations in upper-ocean productivity on the global scale since the first planning workshops for a U.S. global ocean flux program (National Academy of Sciences, 1984). From the start, remote measurements of near-surface chlorophyll a concentrations were envisaged as the major to...
متن کاملAn assessment of optical properties and primary production derived from remote sensing in the Southern Ocean (SO GasEx)
[1] Optical properties and primary production were measured during the Southern Ocean (SO) Gas Exchange Experiment (GasEx) (March–April 2008). To assess and evaluate these properties derived from remote sensing, absorption coefficients derived from remote sensing reflectance (Rrs) with the quasi‐analytical algorithm were compared with those from in situ measurements from both an ac‐9 optical in...
متن کاملAssessment of uncertainties of ocean color parameters for the ocean Carbon-based Productivity Model
With the developments of ocean color remote sensing technology, some ocean color parameters can be derived by satellite globally. These terms, including chlorophyll concentration (Chl), particulate backscattering coefficients (bbp), photosynthetically available radiation (PAR), have been proved to be related to NPP of phytoplankton. Based on these parameters with other auxiliary data, a carbon-...
