Comparison of in situ and satellite ocean color determinations of particulate organic carbon concentration in the global ocean

Oceanologia, 2015
Ocean color satellite missions have provided more than 16-years of consistent, synoptic observations of global ocean ecosystems. Surface chlorophyll concentrations (Chl) derived from satellites have been traditionally used as a metric for phytoplankton ...

iMarNet: an ocean biogeochemistry model intercomparison project within a common physical ocean modelling framework [PDF]

, 2014
Ocean biogeochemistry (OBGC) models span a wide variety of complexities, including highly simplified nutrient-restoring schemes, nutrient–phytoplankton–zooplankton–detritus (NPZD) models that crudely represent the marine biota, models that represent a ...

Improvement of GOCI-II Water Vapor Absorption Correction through Fusion with GK-2A/AMI Data

Remote Sensing, 2023
In remote sensing of the ocean color, in particular, in coarse-resolution global model simulations, atmospheric trace gases including water vapor are generally treated as auxiliary data, which create uncertainties in atmospheric correction.

Multiband Atmospheric Correction Algorithm for Ocean Color Retrievals

Frontiers in Earth Science, 2019
National Aeronautics and Space Administration's (NASA's) current atmospheric correction (AC) algorithm for ocean color utilizes two bands and their ratio in the near infrared (NIR) to estimate aerosol reflectance and aerosol type.

Ocean Color Image Sequences Reveal Diurnal Changes in Water Column Stability Driven by Air–Sea Interactions

Journal of Marine Science and Engineering, 2023
The southward propagation of cold-air frontal boundaries into the Gulf of Mexico region initiates a cascade of coupled air–sea processes that manifests along the coastlines as an apparent brightness anomaly in the ocean color signals.

Estimation of phytoplankton pigments from ocean-color satellite observations in the Senegalo–Mauritanian region by using an advanced neural classifier [PDF]

Ocean Science, 2020
We processed daily ocean-color satellite observations to construct a monthly climatology of phytoplankton pigment concentrations in the Senegalo–Mauritanian region.

A Decade of Satellite Ocean Color Observations [PDF]

Annual Review of Marine Science, 2009
After the successful Coastal Zone Color Scanner (CZCS, 1978–1986) demonstration that quantitative estimations of geophysical variables such as chlorophyll a and diffuse attenuation coefficient could be derived from top of the atmosphere radiances, a number of international missions with ocean color capabilities were launched beginning in the late ...

The Use of VGPM to Estimate Oceanic Primary Production: A “Tango” Difficult to Dance

Journal of Remote Sensing, 2022
One of the primary goals of launching an ocean color satellite is to obtain over the global ocean synoptic measurements of primary production (PP), a measure of phytoplankton photosynthesis.

Evaluation of the CALIPSO Lidar-observed particulate backscattering coefficient on different spatiotemporal matchup scales

Frontiers in Marine Science, 2023
The satellite lidar-derived ocean particulate backscattering coefficient (bbp) has rarely been validated globally with in situ observations, and we need to understand how well the satellite CALIPSO lidar bbp approach performs.

Inversion of multiangular polarimetric measurements from the ACEPOL campaign: an application of improving aerosol property and hyperspectral ocean color retrievals [PDF]

Atmospheric Measurement Techniques, 2020
NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission, scheduled for launch in the time frame of late 2022 to early 2023, will carry the Ocean Color Instrument (OCI), a hyperspectral scanning radiometer, and two multiangle polarimeters (MAPs ...
