Periodic Reporting for period 3 - MULTIPLY (MULTIscale SENTINEL land surface information retrieval PLatform)
Reporting period: 2018-07-01 to 2019-12-31
Our impacts occurred at multiple levels. First of all, we provided retrieval products that already has helped the scientific community and the companies active in space products. For instance, the emulators to speed up calculations have already been used in the FLEX mission, the atmospheric correction routine has been picked up by NASA and so on. Second, by involving key users from the start till the end of the project (from the moment of obtaining their key requirements, to demonstrating the beta-version till training them with e-learning materials in using the MULTIPLY platform), we have raised awareness in the community in the enhanced possibilities of retrieval of land surface features when using our state-of-the-art tools. Moreover, we have run various user demonstrator projects, e.g. we have shown how remote sensing information can be used to better understand the temporal dynamics in crop development (and thus to optimise crop yields). We have provided other satellite operators with an opportunity to cross-calibrate their data to the science-grade Sentinel standards. We have incorporated and validated multiple radiative transfer models using the platform and we have shown how land surface variables derived with the MULTIPLY platform can be used to better constrain global climate-vegetation models. Third, through our philosophy of open-access development, we have created software that can be used by the entire community as it is available on Github, including an e-learning environment for users to be trained in using and adapting the software. Moreover, the MULTIPLY platform is available as virtual machine on DIAS as one of the first validated platforms for retrieval of SENTINELS data. This has allowed for and will continue to stimulate the wider use of SENTINELS data.
