Summary: This study aims to monitor the spatial-temporal pattern of deformation over landfast ice in the Arctic using InSAR. Different sensors showed consistent temporal and spatial patterns of deformation, with horizontal and vertical deformations monitored using a multi-dimensional SBAS technique. The results demonstrated horizontal deformation ranging from -95 to 85 cm, and vertical deformation ranging from -41 to 63 cm in Cambridge Bay, Nunavut, Canada during February-April 2019. The coherence over ice from C-band was maintained over a shorter time interval compared to L-band due to temporal decorrelation.

Summary: With global warming, the degradation of permafrost is causing various issues including thawing subsidence, collapse, and emission of greenhouse gases. Monitoring the permafrost status in the Qinghai-Tibet Plateau is significant for global change and local development. Using satellite data, this study assessed the spatial and temporal permafrost deformation in the northern QTP and found that subsidence is concentrated in braided stream plains and thermokarst lakes. The research also highlighted the sensitivity of L-band ALOS-2 in detecting thermal collapse of permafrost.

Summary: Active landslides along the Jinsha River corridor pose serious threats and attract widespread attention due to their large scale, number, and potential disaster chain characteristics. Conventional InSAR-based methods face challenges in mapping landslides efficiently in this region, leading to the development of a new procedure integrating surface deformation and geomorphological features for large-area landslide mapping.

Summary: Due to the complex terrain, intense tectonic activity, and harsh climate in the Qinling-Daba Mountains, landslides pose a serious threat to local residents. InSAR has been widely used for landslide detection, but its effectiveness is challenged by the steep terrain and dense vegetation in the area. This study compared ALOS/PALSAR-2 and Sentinel-1A data for landslide detection and found that ALOS/PALSAR-2 is more suitable for detecting landslides in areas with high vegetation coverage, meeting over 90% of the monitoring needs. The study provides important scientific support for future landslide monitoring in the area and the accuracy evaluation methods of InSAR monitoring.

Summary: The rapid growth of Sydney has led to the development of residential and transportation infrastructure, but it also brings the issue of land subsidence, which needs to be carefully managed. A new processing framework called Pol-TS-InSAR was developed to analyze land subsidence using Sentinel-1 data and GPS measurements. The analysis revealed that the main factors contributing to subsidence in Sydney are groundwater extraction, mining activities, underground tunnel construction, landfill, and high-rise building construction.

Summary: Seasonal surface deformation is related to groundwater extraction and recharge, and plays a role in guiding groundwater management and subsidence mitigation. In the Taiyuan basin, Northern China, seasonal ground displacement in response to aquifer compaction and expansion was observed, with a one-year periodicity. The deformation showed a correlation with groundwater levels and precipitation patterns.

Summary: InSAR time series analysis is a crucial tool for nationwide land deformation monitoring. With Sentinel-1 SAR data, it is possible to accurately and precisely measure and monitor ground deformation globally. Previous limitations in data quality, analysis techniques, data policy, and processing capacity hindered comprehensive deformation monitoring. However, the availability of ALOS InSAR products and LiCSBAS tool have allowed for easy derivation of deformation data from 2006 to 2011. This study compared the deformation time series and velocity in major urban areas in Japan from 2006 to 2011 with the deformation detected by Sentinel-1 data from 2014 to 2020, revealing various long-term deformation histories and transitions.

Summary: Remote sensing tools have been effective in detecting petroleum hydrocarbons in continental areas. While NIR-SWIR range has been widely used for PHC detection, the use of MWIR and TIR data has been underexplored. This study used SEBASS system to map PHC-impregnated soil substrates and found that PHC features are subtle but increase the emissivity of background features, indirectly highlighting contaminated sites.

Summary: Georeferencing accuracy is crucial for high-quality remote sensing data. The georeferencing of nighttime thermal satellite imagery is challenging due to the complexity of thermal radiation patterns and the coarse resolution of thermal sensors. This paper introduces a novel approach for improving georeferencing using land cover classification products, specifically by using water body edges as matching objects. The results show that this method improves georeferencing by an average of 12.0 pixels.
