It is shown that uncertainties in remote sensing reflectance products have primarily Rayleigh-type spectral components, are associated with the variability of Rayleigh optical thickness and surface effects, and mostly explain the frequency of negative Rrs in coastal waters. The contributions of inaccuracies in aerosol models, which are usually considered as a major factor in uncertainties, were found to be small. The spectral term of water variability inside the pixel(s), which was considered proportional to Rrs, had also a pronounced peak in the green part of the spectrum in coastal waters. Uncertainties in Rrs were typically about 10\u20133<\/sup><\/span> sr\u20131<\/sup><\/span> at 412 nm for VIIRS, and about twice higher for OLCI. The impact of surface effects was estimated separately by accurate measurements of wave slopes variances in several ocean cruises using our multispectral polarimetric system together with a modified polarimetric slope-sensing technique. Several approaches are analyzed for the mitigation of Rrs uncertainties in the blue bands, showing possibilities of their significant reduction in coastal waters.<\/p>\n \n Alex Gilerson<\/b><\/a><\/span>, City College of New York<\/p>\n Eder Herrera-Estrella<\/a><\/span>, City College of New York<\/p>\n Jacopo Agagliate<\/a><\/span>, City College of New York<\/p>\n Mateusz Malinowski<\/a><\/span>, City College of New York<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ custom_padding_last_edited=”on|tablet” _builder_version=”4.14.7″ _module_preset=”default” background_enable_color=”off” background_image=”https:\/\/oceanopticsconference.org\/wp-content\/uploads\/2022\/01\/oo22-banner-bckd.jpg” custom_padding=”0px||11px||false|false” custom_padding_tablet=”0px||11px||false|false” custom_padding_phone=”||27px||false|false” global_module=”2766″ saved_tabs=”all” locked=”off” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_row _builder_version=”4.16″ _module_preset=”default” custom_padding=”0px||8px||false|false” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_social_media_follow use_icon_font_size=”on” icon_font_size=”19px” _builder_version=”4.16″ _module_preset=”default” custom_button=”on” text_orientation=”right” custom_margin=”-10px||11px||false|false” custom_margin_tablet=”-9px||5px||false|false” custom_margin_phone=”-9px||5px||false|false” custom_margin_last_edited=”on|tablet” global_colors_info=”{}” button_text_size__hover_enabled=”on|desktop” theme_builder_area=”post_content”][et_pb_social_media_follow_network social_network=”facebook” url=”https:\/\/www.facebook.com\/OceanOpticsConference\/” _builder_version=”4.16″ _module_preset=”default” background_color=”#9b9b9b” background_enable_color=”on” global_colors_info=”{}” background__hover_enabled=”on|hover” background_color__hover=”#0C71C3″ background_enable_color__hover=”on” theme_builder_area=”post_content” follow_button=”off” url_new_window=”on”]facebook[\/et_pb_social_media_follow_network][et_pb_social_media_follow_network social_network=”twitter” url=”https:\/\/twitter.com\/OceanOpticsConf” _builder_version=”4.16″ _module_preset=”default” background_color=”#9b9b9b” background_enable_color=”on” global_colors_info=”{}” background__hover_enabled=”on|hover” background_color__hover=”#0C71C3″ background_enable_color__hover=”on” theme_builder_area=”post_content” follow_button=”off” url_new_window=”on”]twitter[\/et_pb_social_media_follow_network][\/et_pb_social_media_follow][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_3,1_3,1_3″ use_custom_gutter=”on” gutter_width=”2″ _builder_version=”4.16″ _module_preset=”default” custom_padding=”13px||34px|0px||” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”1_3″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.16″ _module_preset=”default” header_font_size=”26px” header_2_font=”|||on|||||” header_2_text_align=”center” header_2_text_color=”#FFFFFF” header_2_font_size=”21px” text_orientation=”center” custom_margin=”||5px|||” global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.16″ _module_preset=”default” text_text_color=”#FFFFFF” link_font=”||||on||||” link_text_color=”#FFFFFF” header_2_text_color=”#FFFFFF” max_width=”300px” module_alignment=”center” custom_margin=”||||false|false” custom_margin_tablet=”||-3px||false|false” custom_margin_phone=”” custom_margin_last_edited=”on|tablet” custom_padding_tablet=”||||false|false” custom_padding_phone=”||32px||false|false” custom_padding_last_edited=”on|phone” global_colors_info=”{}” link_text_color__hover_enabled=”on|hover” link_text_color__hover=”#a8a8a8″ theme_builder_area=”post_content”]<\/p>\n Sign up to receive email updates to be sure to catch all the meeting news.
