The calibration steps ensure that the data received from the space borne instrument are converted into meaningful and accurate radiance in physical units.

OCO-2 and OCO-3 use high resolution imaging spectrometers to measure solar radiance reflected by the Earth atmosphere and surface at high spectral resolution ( ...

The techniques developed for OCO-2 are being applied to the Orbiting Carbon Observatory 3, which completed in-orbit checkout in August 2019.

The OCO-2 measurement approach concentrates on gathering data near the Earth's surface, where almost all of the CO 2 sources and sinks are located.

It incorporates three high-resolution spectrometers that make coincident measurements ofreflected sunlight in the near-infrared CO2 near 1.61 and 2.06 ...
