SICE: Sentinel-3 Snow and Ice Properties Retrieval

Latest operational SICE version developed by @RasmusBahbah.
It uses PTEP2, SentinelHub and pySICEv2.1.

SICE: Sentinel-3 Snow and Ice Properties Retrieval

This release contains the script used for @AdrienWehrle 's NRT processing active in 2021, 2022 and 2023 and the so-called "showcase" reprocessing. It is being replaced by https://github.com/GEUS-SICE/SICE-EDC that uses PTEP2, SentinelHub and pySICEv2.1. The present release is for archiving purpose.

This data was used for the following study:

Box, J. E., Wehrlé, A., van As, D., Fausto, R. S., Kjeldsen, K. K., Dachauer, A., et al. (2022). Greenland ice sheet rainfall, heat and albedo feedback impacts from the mid-August 2021 atmospheric River. Geophysical Research Letters, 49, e2021GL097356. https://doi.org/10.1029/2021GL097356

This release is an improvement from SICEv2.3.1.

This toolchain does the following:

• Fetch S3 OLCI & SLSTR products
• Process OLCI & SLSTR using SNAP GPT
• Process using pySICE
• Build daily mosaic

Specificities of this release:

• Designed for SNAP8 and tie-point geocoding
• Using pySICEv1.4

SICE: Sentinel-3 Snow and Ice Properties Retrieval

This release is for archiving purpose.
This release archives the branch called "bav-dev".

This release is an improvement from SICEv2.4 but was never used operationally.
It has been ported successfully to PTEP2 by Sinergise but reprocessing was put on hold because a new version of pySICE was underway.

This toolchain does the following:

• Fetch S3 OLCI & SLSTR products
• Process OLCI & SLSTR using SNAP GPT
