研究目的
To document the physical characteristics of snow and ice-covered surfaces and their spatial and temporal variability using satellite remote sensing data.
研究成果
The article concludes that satellite remote sensing is a powerful tool for studying snow and ice-covered surfaces, offering insights into their physical characteristics and spatio-temporal variability. It highlights the importance of multi-sensor approaches, the processing of large satellite data archives, the assimilation of satellite data into models, and the definition of future satellite missions for cryosphere monitoring.
研究不足
The limitations include the need for in situ measurements to calibrate certain remote sensing data, the challenge of automating the identification and mapping of glacier contours, especially when covered by debris or in shadowed areas, and the difficulty in modeling the interactions between electromagnetic radiation and sea ice due to its complex nature.
