Inter-comparison OCI
The radiance measured by the SPEXone instrument is compared to the radiance measured by the OCI instrument. This is done for specific regions, listed in the table below. Only pixels with a solar zenith angle below 60 degrees and a homogeneous cloud-region of 50×50 km2 are chosen. For the pixels passing these requirements and the region-specific requirements the radiance is taken from both instruments and the SPEXone radiance is divided by the OCI instrument. A monthly mean is
taken of this fraction and is shown in the plots. A separate plot is made for each region and each plot has a separate line for each chosen wavelength.
| Region id | General location | Latitude range | Longitude range | Requirements |
| 0 | Pacific Ocean | TBD | TBD | • Clear sky |
| 1 | Pacific Ocean | TBD | TBD | • Fully cloudy • Cloud optical thickness > 10 |
| 2 | Sahara Desert | TBD | TBD | • Clear sky |
| 3 | Antarctica | TBD | TBD | • Clear sky |
| 4 | Railroad Valley | TBD | TBD | • Clear sky |

About
SPEXone is being developed by a Dutch consortium consisting of SRON Netherlands Institute for Space Research (SRON) and Airbus Defence and Space Netherlands (Airbus DS NL), supported by optical expertise from the Netherlands Organisation for Applied Scientific Research (TNO). SRON and Airbus DS NL are responsible for the design, manufacturing and testing of the instrument. The scientific lead is in the hands of SRON. SPEXone is a public-private initiative funded by the Netherlands Space Office (NSO), the Netherlands Organization of Scientific Research (NWO), SRON, and Airbus DS NL.
