Abstract

Remotely sensed data are generally analyzed assuming flat terrain. As the spectral signature of the ground depends upon the orientation of the surface slope, the topography has to be considered for efficient radiometric corrections in mountainous regions. In this paper, we present a modelization of the atmospheric downward radiance at the ground level which gives us the relative contributions of the direct solar beam and of the diffused radiation for different atmospheric turbidities and different solar incidence angles. Lastly, we estimate the influence of the topography on these contributions to show up which effects can be neglected.

Synthesizing long-term satellite imagery consistent with climate data: Application to daily snow cover
2024, Remote Sensing of Environment
High-resolution daily snow cover estimation is challenging due to irregular satellite data availability. In this study, we create synthetic 30 m snow cover images for dates with no satellite data. It is based on the relationship between meteorological predictors and available clear sky 30 m Landsat/Sentinel-2 snow cover images. Our approach relies on the fact that while snow cover can vary in a matter of days, its patterns may repeat from year to year if meteorological characteristics are similar. In this context, we apply a K-nearest neighbor algorithm with a similarity metric tailored to estimating snow cover.
The approach is tested with different data availability scenarios to generate twenty years of daily synthetic snow cover images for two regions of interest in Switzerland. The results are assessed based on a leave-one-out analysis, comparisons with PlanetScope, MODIS, and Copernicus High Resolution Snow & Ice Fractional Snow Cover On Ground (HRSI-FSCOG) images, comparisons with data collected at ground stations, and a comparison with a simple snow accumulation and melt model.
The performance of our mapping approach suggests that it is possible to use recurrent snow patterns and climate reanalysis to generate missing data that are virtually and statistically indistinguishable from real observations. The results also indicate that low-resolution climate data, such as in the ERA5-Land reanalysis dataset, provide sufficient performance in the generated synthetic snow maps, opening possibilities for applications in areas with limited in situ snow or climatic data. Our approach could be used to create historical snow cover images for Pre-Satellite periods, or even for future periods by using climate projections.
Estimating global downward shortwave radiation from VIIRS data using a transfer-learning neural network
2022, Remote Sensing of Environment
In recent years, machine learning (ML) has been successfully used in estimating downward shortwave radiation (DSR). To achieve global estimations, traditional ML models need sufficient ground measurements covering various atmospheric and surface conditions globally, which is difficult to accomplish. Training on the simulated data of a radiative transfer model (RTM) is a possible solution, but widely used RTMs ignore some complex cloud conditions which brings bias to simulations. In this study, a neural network applied with the transfer-learning (TL) concept is introduced to utilize both radiative transfer simulations and ground measurement data, achieving global DSR estimation with only top-of-atmosphere and surface albedo at local solar noon as inputs. The proposed method estimates both instantaneous and daily DSR from Visible Infrared Imaging Radiometer Suite (VIIRS) data at 750-m resolution, and both the estimates are validated by 40 independent stations globally. The root mean-square error and relative root mean square error of instantaneous DSR validation over 25 Baseline Surface Radiation Network, seven Surface Radiation Network, and eight Greenland Climate Network stations in 2013 were 91.2 (16.1%), 106.3 (18.3%), 75.0 (24.2%) W/m², respectively, and the daily validation achieved 30.8 (15.5%), 33.5 (17.6%), and 31.3 (14.4) W/m², respectively. The proposed method presents significant high accuracy over polar regions and similar performances over other areas compared with traditional ML models, physics models (e.g., look-up tables and direct estimations), and existing DSR products. The algorithm is also applied to VIIRS swath data to test its global efficacy. Instantaneous mapping captures the spatial pattern of the cloud-mask product, and daily mapping shows spatial patterns similar to the Clouds and the Earth's Radiant Energy System Synoptic TOA and surface fluxes and clouds product, but with more detail. Further analysis indicates that model performance is less sensitive to the quantity of training data after TL has been incorporated. This study demonstrates the advantages of TL on boosting both the generality and accuracy of DSR estimation, which can potentially be applied to other variable retrievals.
Spatial Analysis and Modeling in Geomorphology
2022, Treatise on Geomorphology
Rapid advancements in remote sensing and geospatial information technologies provide Earth scientists new opportunities to utilize high-resolution geospatial datasets for investigating and mapping landforms and geomorphological systems. Advances in spatial analysis and modeling algorithms, approaches and parameterization schemes also enable scientists to better characterize landscape biophysical and structural conditions, morphometric properties of the topography, process mechanics and system dynamics. This article describes the fundamentals of spatial analysis and modeling techniques and approaches, in the context of current capabilities and research opportunities. Issues associated with analysis and modeling efforts are also highlighted. Challenges include concept representation and formalization, empiricism, spatial information synthesis, data volume and computational issues. Nevertheless, rigorous spatial analysis and modeling efforts that quantitatively formalize spatial, temporal and geomorphic concepts can significantly improve our understanding of the characteristics of geomorphological systems and the complex nature of topographic evolution.
Numerical Modeling Issues for Understanding Complex Debris-Covered Glaciers
2022, Treatise on Geomorphology
Debris-covered glaciers play a critical role in governing mountain geodynamics and relief production. Numerous process and system couplings regulate glacier dynamics at various spatial and temporal scales, and understanding glacier sensitivity to climate change is notoriously difficult. Consequently, numerical models are needed to investigate the ablation, accumulation and sediment-transport dynamics that govern glacier geomorphological responses to climate forcing. This chapter addresses glacier modeling issues for characterizing surface energy balance, ablation, meltwater production, supraglacial debris fluxes, ice-flow dynamics and glacial erosion. We highlight numerous modeling issues regarding specific processes, subsystem coupling and feedbacks, model input and validation, and identify research directions for future studies.
