Operational Sentinel-3 snow and ice products (SICE)

derived Data olci on-demand polar products sentinel hub sentinel-3


Operational Sentinel-3 snow and ice products (SICE) is a modification of the original algorithm developed by the Geological Survey of Denmark and Greenland (GEUS) which is available here. The algorithms were originally developed after the work from Kokhanovsky et al. (2018, 2019, 2020). The EDC SICE algorithm produces the same results but it's integrated with the Sentinel Hub infrastructure which allows the user to obtain the results much faster and at higher resolutions. The algorithm uses the already geopositioned and orthorectified S3 - Ocean and Land Color Instrument (OLCI) data provided by Sentinel Hub API in order to calculate different snow optical properties such as snow spectral and broadband albedo and also snow microstructure (snow specific surface area and effective optical grain size). Theoretical basis of the algorithm can be obtained here and here. Since the algorithm relies heavily on the sun zenith angle (SZA), the best results for the northern polar regions can be obtained for the periods between May and September (depending on the location Latitude). To generate the SICE data, navigate to EDC Browser, select the required input parameters and follow the check-out wizard to complete your order. Produced data will be uploaded directly into your JupyterLab environment on EDC.
