Special Issue Information

Dear Colleagues,

Snow and ice cover, which are key components of the cryosphere, are crucial for regulating Earth’s energy balance due to their high albedo. Their high reflectivity causes a significant portion of incoming solar radiation to be reflected back into space, contributing to cooler global temperatures. Crucially, even small changes in snow and ice albedo can significantly impact the climate system, accelerating melting, raising sea levels, and initiating complex feedback loops. Therefore, understanding and accurately monitoring the factors controlling snow and ice albedo variations are paramount for climate research and prediction.

This Remote Sensing Special Issue seeks to compile cutting-edge research advancements in remote sensing regarding snow cover, snow albedo, and their influencing factors (e.g., light-absorbing particles). Aligned with the journal’s scope, encompassing the application of remote sensing technologies to understand cryospheric processes and land surface–atmosphere interactions, this issue will facilitate interdisciplinary collaboration, contributing to enhanced predictive capabilities in climate change studies and improving our ability to monitor and model these critical cryospheric parameters.

We invite submissions covering a range of relevant themes, including, but not limited to, the following:

  • Novel remote sensing techniques and algorithms for detecting snow cover and retrieving snow albedo.
  • Analysis of the spatial and temporal variability of snow cover and snow albedo from local to global scales.
  • The influence of surface characteristics (e.g., grain size, snow morphology) on albedo.
  • The impact of light-absorbing particles (LAPs), such as black carbon and dust, on snow and ice albedo reduction.
  • Field campaigns and in situ measurements validating remote sensing albedo products.

High-resolution optical remote sensing imagery plays a crucial role in monitoring the Earth’s surface. However, cloud obstruction and spectral confusion between clouds and snow significantly compromise data quality and application reliability, leading to persistent cloud overestimation in optical remote sensing products. To address this challenge, this study developed an enhanced multi-threshold cloud detection algorithm based on AVHRR surface reflectance data, which incorporates dynamic threshold optimization within a multi-level decision tree framework. Utilizing Landsat 5 SR as reference data, the algorithm demonstrated superior cloud-snow discrimination capability, achieving an overall accuracy (OA) of 82.08%, with the user’s accuracy (UA) and F-score reaching 79.41% and 82.55%. Comparative evaluation demonstrates that the proposed algorithm outperforms two existing algorithms, with OA improvements of 17.42% and 7.93%, respectively. A particularly notable enhancement is the significant reduction in cloud misidentification, as reflected by UA increases of 21.02% and 13.21%. These improvements are most pronounced in high-altitude mountainous regions with snow cover. The algorithm maintains computational efficiency while providing reliable cloud masking, thereby offering enhanced support for snow cover monitoring and broader environmental applications.

By combining the Maxwell–Garnett mixing rule, Mie scattering, and the four-stream discrete ordinates adding method, a snow albedo model with explicit consideration of water content was constructed, and the influence of snow water content on snow albedo simulation was systematically analyzed. The results indicate that liquid water content is the key factor contributing to significant changes in albedo in the near-infrared band. The albedo of snow with small particle sizes is more sensitive to water content. The water content in the surface layer of snow has a more pronounced effect on reducing albedo. The actual measurement cases at the stations on the Tibetan Plateau, Xinjiang, and Northeast China show that the model established here provides a good simulation of albedo accuracy, with a bias of −0.0069 and a Root Mean Square Error (RMSE) of 0.0583 compared to the observations. This indicates that the model has a strong ability to express physical mechanisms and performs stably in complex environments, thereby demonstrating good regional applicability. This model can also be applied to wet snow containing impurities in the future. Full article
