About this technology

Overview

NASA-JPL's OCO-3 is an instrument onboard the International Space Station that measures carbon dioxide in the Earth's atmosphere. OCO-3 is similar in design to its predecessor, OCO-2, with the addition of the Pointing Mirror Assembly (PMA) which essentially allows the instrument to focus its observations on the area surrounding a given location of interest on a single overflight. This is called a Snapshot Area Map, or SAM, and is the focus of this software. This software takes daily OCO-3 CO2 input, isolates SAM captures, and fits the data to a global, fixed grid for a level 3 output product.
