Modeled ocean life and chemistry (monthly)

NASA Ocean Biogeochemical Model assimilating satellite chlorophyll data global monthly VR2017 (NOBM_MON) at GES DISC
biosphere NASA GES_DISC Level 4
In plain English

What it measures. Offers a monthly modeled picture of ocean life and chemistry, including several groups of phytoplankton and nutrients plus dissolved organic and inorganic carbon, across the open ocean.

How it's made. Produced by the NASA Ocean Biogeochemical Model, which couples ocean biology, circulation, and light, and is nudged toward reality using satellite chlorophyll observations.

How & where you'd use it. Helps researchers study how ocean ecosystems and the carbon cycle work and change over time on a global scale.

Official description

This is the assimilated monthly data from NASA Ocean Biogeochemical Model (NOBM). The NOBM is a comprehensive, interactive ocean biogeochemical model coupled with a circulation and radiative model in the global oceans (Gregg and Casey, 2007). It spans the domain from -84 to 72 degree latitude in increments of 1.25 degree longitude by 2/3 degree latitude, including only open ocean areas where bottom depth >200m. NOBM contains 4 phytoplankton groups, 4 nutrient groups, a single herbivore group, and 3 detrital pools, and the major ocean carbon components, dissolved organic and inorganic carbon (DOC and DIC).
