This document summarizes the availability and market readiness of the MONOCLE reference sensor collection, which consists of high-end radiometry sensors and supporting platforms for field deployment to register hyperspectral reflectance (water colour) and atmospheric conditions. The original targets for each of the three sensor systems were met in two cases (HSP-1 and So-Rad) whereas the WISP-M is still under development, with a timeline to completion provided for marketing purposes. The demonstration of this deliverable is provided through the project website, which provides user guidance, cost/pricing (where available) or information on the pathway to market. Additional materials targeted at specific user groups, such as instructional videos, build guides, manuals and software tools, are also collected there, either as part of this deliverable or the associated D8.5 “Set of MONOCLE documentation per stakeholder audience” and D6.3 “Software library for data inspection and statistical information extraction”. Despite some production issues, often related to the 2020/2021 COVID-19 pandemic, prototypes of each of the three systems (the WISPStation representing the WISP family of sensor systems) has had long-term field exposure, generating data sets and supporting the development of operational, standardardized data flows. This has resulted in the achievement of TRLs near, at or beyond the initially planned targets. All sensor systems now move forward into the last phase of the project which is focussed on demonstrating new and improved capabilities in the in situ segment of Copernicus, with and for selected end-user communities.
