Radiometric Stability
The radiance measured by the SPEXone instrument is collected for specific regions where this radiance is expected to be relatively stable. The exact coordinates of the center points of these regions and the extent of these regions is TBD. Two different analyses are done: one for all (near-)cloud-free pixels and one for all (near-)cloud-filled pixels. Glint pixels are excluded from this analysis. The mean and median radiance are plotted as a monthly average. A separate plot is made for each region and viewport and each plot has a separate line for each chosen wavelength.

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.
