Outline
• NOAA/NESDIS snow mapping/monitoring activities
• Snow products: Application in mountainous regions
Snow cover: Needs and Requirements
Requirements to snow products
• Daily, Spatially continuous
• Continental or global scale coverage
• 1-4 km resolution
Surface observations are not enough, satellite data should be used
NOAA needs information on snow for
• Weather prediction
• Climate studies
• Hydrological forecasts, flood warnings
Snow cover: Techniques
Satellite-based snow mapping techniques used
• Interactive
• Automated
- Visible & infrared
- Passive microwave
- Combined visible-infrared-microwave
Focus on operational polar and geostationary satellites & sensors
