.. _intro: .. raw:: latex \listoffigures \listoftables ============ Introduction ============ Project background ================== The SEOM Sentinel-3 for Science, Land Study 1: SNOW (referred as 'S3-SNOW' in the following) is “to develop, implement and validate algorithms for deriving several key snow parameters from Sentinel 3 optical satellite data, appropriate for addressing ESA’s Cryosphere challenge C3 : "Seasonal snow, lake/river ice and land ice, their effect on the climate system, water resources, energy and carbon cycles: the representa`_ which have been developed in the frame of the S3-SNOW project and its successor SICE. Its purpose is to describe in detail how to obtain, install and operate these processors. Also, a comprehensive overview of the related data products (input as well as intermediate and final products) is provided. The explicit structure of the document is as follows: * Chapter 1 is this introduction. * `Chapter 2 `_ gives an overview of the SNAP S3-SNOW and SICE processors. * `Chapter 3 `_ describes all relevant S3-SNOW and SICE products. * `Chapter 4 `_ explains how to get and install the processing software. * `Chapter 5 `_ explains how to run the processing software.
