MSI is a reflectance measurement, sensitive to increases in leaf water content using the forumla MSI=b11/b8. See Rock et al. (1985) DOI: As water content in vegetation canopy leaves increases, the absorbtion at wavelengths around 1599 nm also increases. Absorption at 819nm is used as a reference, since it’s nearly unaffected by changes in water content. Applications of the MSI include canopy stress analysis, productivity prediction and modelling, fire hazard analysis, and studies of ecosystem physiology. The index is inverted relative to the other water vegetation indices; higher values indicate greater water stress and less water content. The values of this index range from 0 to more than 3. The common range for green vegetation is 0.4 to 2. Values are provided as integer and multiplied by 1000 Metrics: annual (_annual) and seasonal (_spring; _summer; _autumn; _winter) mean (_nanmean), standard dev (_nanstd), min (_nanmin), max (_nanmax), median (_nanmedian), and amplitude (_range) Data format: GeoTiff Gregory Giuliani UNIGE/GRID gregory.giuliani@unige.ch Denisa Rodila UNIGE/GRID denisa.rodila@unepgrid.ch Bruno Chatenoux UNIGE/GRID bruno.chatenoux@unepgrid.ch vegetation msi landscape model raster data nature geocat.ch 2022-09-28 geonetwork.thesaurus.external.theme.geocat.ch Creative Commons Attribution 4.0 International 25000 eng imageryBaseMapsEarthCover environment geoscientificInformation 5.9548 10.467 45.821 47.801 2016-01-01 2021-12-31 https://doi.org/10/gqvjk6 DOI Moisture Stress Index (MSI) - Switzerland [2016] https://doi.org/10/gqvjk3 DOI Moisture Stress Index (MSI) - Switzerland [2017] https://doi.org/10/gqvjk4 DOI Moisture Stress Index (MSI) - Switzerland [2018] https://doi.org/10/gqvjk5 DOI Moisture Stress Index (MSI) - Switzerland [2019] https://doi.org/10/gqvjk2 DOI Moisture Stress Index (MSI) - Switzerland [2020] https://doi.org/10/gqvjk8 DOI Moisture Stress Index (MSI) - Switzerland [2021] This dataset has been produced using Sentinel-2 data from the Swiss Data Cube
