Measuring CO2 across the Atlantic

Royal Research Ship James Clark Ross started its roughly 4000 miles, 40 days voyage across the Atlantic Ocean at the end of September.

It has been carrying out in situ measurements with an array of instruments including above-water radiometric optical sensors that measure upwelling radiance from the sea surface for validation of satellite ocean colour, infrared radiometers that measure the skin temperature of the ocean used to validate satellite sea-surface temperature, C-band radar which characterises wave properties that are detected by the Copernicus Sentinel 1 satellite, and eddy covariance which is a measure of the carbon dioxide (CO2) flux between the atmosphere and the ocean.
