Introduction

Need for timely and accurate snow cover mapping: - May cover up to 40% of the Earth's surface,

- Energy and water cycle of Earth,

- High reflectance and low thermal conductivity,

- A significant determinant of the Earth's radiation budget,

- A vital source of irrigation and drinking water supply,

- A major input component of General Circulation Models.
