Comparison of areal extent of snow as determined by AVHRR and SSM/I satellite imagery by Robert W. Maxson Download PDF EPUB FB2

Advanced Very High Radiometric (AVHRR) and Special Sensor Microwave Imager (SSM/I) imagery are compared to determine the areal extent of snow. A multi-spectral AVHRR algorithm, utilizing channels 1 (um), 2 ( am), 3 (um), and 4 (Oum), creates a synthetic image that classified land, snow, water and clouds.

7 Weather and Air Quality: Minutes to Subseasonal INPUT SUMMARY. Weather and air quality simulations have greatly improved over the past decade. These advances are in large part due to improved data assimilation, atmospheric physics and chemistry models, faster computers, and observations that improve, validate, evaluate, and initialize deterministic and ensemble forecast models.

The Arctic is a region in transformation. Warming in the region has been amplified, as expected from ice-albedo feedback effects, with the rate of warming observed to be ~ ± °C/decade in the Arctic (>64°N) compared to ~°C/decade globally during the last three decades.

This increase in surface temperature is manifested in all components of the cryosphere. You can write a book review and share your experiences.

Satellite Remote Sensing and GIS Applications in Agricultural Meteorology Observing System to include appropriate Research and Development (R&D) satellite missions. The recently established WMO Consultative Meetings on High-Level Policy on Satellite Matters have acted as a catalyst in each of these interwoven and important areas.

Improved estimates of snow extent, and thereby of the behavior of albedo, provide essential information for climate research, numerical weather prediction (NWP) and hydrological forecasting.

Long-term time series of satellite data estimates of seasonal snow cover are needed for constructing climate data records (CDR) essential for climate research.
