Research on the crustal structure of Princess Elizabeth Land (PEL) is of great importance for studying the composition and tectonic evolution of East Antarctica, and the structure and property feature given by gravity and magnetic anomalies is an effective way to analyze the subglacial crust structure. We collected digital elevation data, satellite gravity data and aeromagnetic data from PEL, and established the density and magnetic susceptibility structure of the crust in the study area through gravity and magnetic inversion methods.

Sea ice concentration is important because it helps in determining important climate variables. Together with sea ice thickness, important fluxes between air and sea as well as heat transfer between the atmosphere can be determined. We designed an adapted bootstrap algorithm called SARAL/AltiKa Sea Ice Algorithm (SSIA) with some tunings and segregated the algorithm into winter and summer algorithms to estimate daily sea ice concentration (SIC) in the Arctic.

When considering urban growth in metropolitan areas, polycentric urban structures have been significantly observable everywhere, both in developing and developed nations. Morphological urban developments have been considered in many studies, and recently, attention has been paid to polycentric cities. Polycentricism is a collective concept that works at local, regional, and national levels. However, the development of polycentric urban spaces includes a multitude of decentralized morphologies and functional properties that have significant impacts.
