PhD Position (f/m/x) – Remote Sensing of Biodiversity Helmholtz-Gemeinschaft Deutscher Forschungszentren https://recruitingapp-5128.de.umantis.com/Vacancies/2019/Description/2 The Helmholtz Centre for Environmental Research (UFZ) with its 1,100 employees has gained an excellent reputation as an international competence centre for environmental sciences. We are part of the largest scientific organisation in Germany, the Helmholtz association. Our mission: Our research seeks to find a balance between social development and the long-term protection of our natural resources. The newly established Remote Sensing Centre for Earth System Research (RSC4Earth) - a joint initiative of UFZ and the Faculty of Physics and Earth Sciences at Leipzig University - conducts innovative research to advance the understanding of the Earth system via the integration of various remote sensing, data science, and process-oriented modelling techniques. It has extensive research experience in quantifying land sur

Snow Geophysics and Remote Sensing Graduate Opportunities starting January 2021 Boise State University The Department of Geosciences at Boise State University (Boise, Idaho, USA) has immediate openings for MSc and PhD geophysics applications on a project funded by the U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) entitled "Advancement of snow monitoring for water resources, vehicle mobility, and hazard mitigation: using optical, microwave, acoustic, and seismic techniques". This project aims to improve our ability to map snow properties related to hydrology and vehicle mobility, and to monitor avalanche events, using remote sensing and geophysics.   Graduate positions are currently available to focus on 1) LiDAR and optical remote sensing of snow, 2) ground-based and InSAR radar remote sensing of snow, and 3) seismo-acoustic sensing of snow. All three projects involve data acquisition with state-of-the-art instrumentation, numerical modeling, interpretati

Difference between Kriging and IDW. What does kriging mean? least squares estimate. Kriging is a type of regression that gives a least squares estimate of data (Remy et. ... Unlike linear regression or inverse distance weighted interpolation, kriging interpolation is based primarily on empirical observations, the observed sample data points, rather than on a pre-assumed model. What is GIS IDW? Inverse Distance Weighted (IDW) is a method of interpolation that estimates cell values by averaging the values of sample data points in the neighborhood of each processing cell. ... Specifying a lower power will give more influence to the points that are farther away, resulting in a smoother surface. Which interpolation method is best? The most used and promising techniques are universal Kriging and linear regression models in combination with Kriging (residual Kriging) or IDW. E.g.: Air temperature data – Kriging is most likely to produce the best estimation of a continuous surface, followed by

Postdoc in remote sensing and ecosystem modelling Swiss Federal Institute for Forest, Snow and Landscape Research Swiss Federal Institute for Forest, Snow and Landscape Research WSL The Swiss Federal Institute for Forest, Snow and Landscape Research WSL is part of the ETH Domain. Approximately 600 people work on the sustainable use and protection of the environment and on the handling of natural hazards. The Research Unit Forest Dynamics assesses the effects of changing environmental conditions on forest ecosystem functioning. We are offering for 7 months a position as Postdoc in remote sensing and ecosystem modelling You will investigate ecosystem photosynthesis and impacts of extreme cold temperature events in the early season. The challenge is to identify causes, understand mechanisms, and to quantify effects at the continental scale. To achieve this, you will work with ecosystem eddy covariance flux measurements from a large number of sites, develop model parametrisations to resolv

PhD Student Position in SAR Interferometry/Tomography ETH Zürich https://www.jobs.ethz.ch/job/view/JOPG_ethz_z8iB6dwPZotqZhGZ9t The Earth Observation and Remote Sensing Group, Institute of Environmental Engineering, at ETH Zurich is seeking a PhD student for a research project on Interferometric / Tomographic Techniques in Synthetic Aperture Radar (SAR) Remote Sensing to Monitor Surface Displacements starting from autumn/winter 2020/2021. Job description The research focuses on investigating methods and algorithms in the context of synthetic aperture radar (SAR) multibaseline interferometry and SAR tomography for space-based monitoring of ground-surface displacements. By using repeat-pass SAR interferometry, deformation measurements at cm/mm level over longer time spans can be obtained for extended areas. SAR interferometry therefore complements point-based measurement techniques such as observations with total station theodolites, Global Navigation Satellite System (GNSS)-based, or le

Postdoc position on mass changes of mountain glaciers (1.0 FTE) Utrecht University http://ssl1.peoplexs.com/Peoplexs22/CandidatesPortalNoLogin/Vacancy.cfm?PortalID=4063&VacatureID=1129928&Vacancy=Postdoc%20position%20on%20mass%20changes%20of%20mountain%20glaciers%20%281%2E0%20FTE%29#top Functie The ice volume stored in mountain glaciers is only a fraction of that in the Greenland and Antarctic ice sheets. Yet, combined they represent the largest land ice contributor to sea level rise in the 20th century, and will continue to play a prominent role in the decades to come. Although it is well established that mountain glaciers are losing mass rapidly, quantification of the processes driving these changes remains challenging. Surface mass balance (SMB) processes - such as snowfall and melt - are driven by the atmosphere, whereas glacier discharge through ice dynamics are predominantly modulated by ice-ocean interaction and internal processes. Clearly, the physics driving the two pr
