Polarimetric Zero-Point
A selection of the smallest DoLP (degree of linear polarization) measurements is collected for the verification over bright clouds (cloud optical thickness > 30) and a scattering angle between 160 and 180 degrees. In these cases, it is expected that the DoLP is near-zero (within 0.001). From the pixels that pass the requirements the mean and median value of the smallest 1% of DoLP values is taken. The mean and median are shown as a monthly average. A separate plot is made for each 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.
