PhD position: Remote Sensing in Hydrology Georgia Institute of Technology




PhD position: Remote Sensing in Hydrology Georgia Institute of Technology

Start date: January 2021.

A PhD position is available in the School of Civil and Environmental Engineering at the Georgia Institute of Technology (Georgia Tech). The position is part of the project "Soil Moisture Dynamics And Water Fluxes In The Amazon Basin During Dry Periods And Droughts-An Application of SMAP Observations" funded by NASA. The successful applicant will join the Prof. Jingfeng Wang research group and will collaborate with project partners at JPL (Andreas Colliander) and the LBNL (Robinson Negron-Juarez).

The main objective of the project is to produce process-based algorithms to improve SMAP soil moisture observations in the Amazon using extensive field data. Experience in field campaigns, excellent communication and writing skills, and programing knowledge (Fortran and python) are needed for this position. Trips to the Amazon rain forest will be part of this position too.

Please check the Georgia Tech home page for details about the graduate student program requirements ([http://grad.gatech.edu/degree-programs](http://grad.gatech.edu/degree-programs)). For specific details about the position please contact Prof. Jingfeng Wang at [Jingfeng.wang@ce.gatech.edu](mailto:Jingfeng.wang@ce.gatech.edu)

Atmospheric Window

The atmospheric window in remote sensing refers to specific wavelength ranges within the electromagnetic spectrum that can pass through the Earth's atmosphere relatively unimpeded. These windows are crucial for remote sensing applications because they allow us to observe the Earth's surface and atmosphere without significant interference from the atmosphere's constituents. Key facts and concepts about atmospheric windows: Visible and Near-Infrared (VNIR) window: This window encompasses wavelengths from approximately 0. 4 to 1. 0 micrometers. It is ideal for observing vegetation, water bodies, and land cover types. Shortwave Infrared (SWIR) window: This window covers wavelengths from approximately 1. 0 to 3. 0 micrometers. It is particularly useful for detecting minerals, water content, and vegetation health. Mid-Infrared (MIR) window: This window spans wavelengths from approximately 3. 0 to 8. 0 micrometers. It is valuable for identifying various materials, incl

DRA Disaster Risk Assessment

Disaster Risk Assessment (DRA): A Professional Overview Disaster Risk Assessment (DRA) is a systematic process used to identify, analyze, and evaluate the potential hazards, vulnerabilities, and risks posed by disasters to people, property, infrastructure, and the environment. It is a critical tool for effective disaster risk management, enabling communities, organizations, and governments to make informed decisions and implement appropriate mitigation measures. Key Components of DRA Hazard Identification: Identifying the types of hazards that could potentially affect a specific area, such as natural disasters (earthquakes, floods, cyclones), technological disasters (industrial accidents, infrastructure failures), or man-made disasters (conflicts, pandemics). Vulnerability Assessment: Evaluating the susceptibility of people, infrastructure, and the environment to the identified hazards. This involves assessing factors such as location, construction quality, socio-economic co

Linear Arrays Along-Track Scanners or Pushbroom Scanners

Multispectral Imaging Using Linear Arrays (Along-Track Scanners or Pushbroom Scanners) Multispectral Imaging: As previously defined, this involves capturing images using multiple sensors that are sensitive to different wavelengths of electromagnetic radiation. Linear Array of Detectors (A): This refers to a row of discrete detectors arranged in a straight line. Each detector is responsible for measuring the radiation within a specific wavelength band. Focal Plane (B): This is the plane where the image is formed by the lens system. It is the location where the detectors are placed to capture the focused image. Formed by Lens Systems (C): The lens system is responsible for collecting and focusing the incoming radiation onto the focal plane. It acts like a camera lens, creating a sharp image of the scene. Ground Resolution Cell (D): As previously defined, this is the smallest area on the ground that can be resolved by a remote sensing sensor. In the case of linear array scanne

Discrete Detectors and Scanning mirrors Across the track scanner Whisk broom scanner.

Multispectral Imaging Using Discrete Detectors and Scanning Mirrors (Across-Track Scanner or Whisk Broom Scanner) Multispectral Imaging:  This technique involves capturing images of the Earth's surface using multiple sensors that are sensitive to different wavelengths of electromagnetic radiation.  This allows for the identification of various features and materials based on their spectral signatures. Discrete Detectors:  These are individual sensors that are arranged in a linear or array configuration.  Each detector is responsible for measuring the radiation within a specific wavelength band. Scanning Mirrors:  These are optical components that are used to deflect the incoming radiation onto the discrete detectors.  By moving the mirrors,  the sensor can scan across the scene,  capturing data from different points. Across-Track Scanner or Whisk Broom Scanner:  This refers to the scanning mechanism where the mirror moves perpendicular to the direction of flight.  This allows for t

Hazard Vulnerability Exposure Risk

Key Concepts in Hazard Identification, Vulnerability Assessment, Exposure Assessment, and Risk Analysis Hazard-Exposure-Vulnerability-Risk (HEVR) Framework: Hazard: A potential event or phenomenon that can cause harm. Exposure: People, assets, or environments in harm's way. Vulnerability: Susceptibility to damage or harm from a hazard. Risk: The potential for loss or damage resulting from the interaction of hazards, exposure, and vulnerability. Risk as a Function: Risk can be calculated using the formula: Risk = Hazard × Vulnerability × Exposure. Reducing any of these factors can decrease overall risk. Types of Hazards: Natural hazards: Earthquakes, floods, tsunamis, landslides, hurricanes. Anthropogenic hazards: Industrial accidents, pollution, infrastructure failure, climate change. Technological hazards: Nuclear accidents, chemical spills. Vulnerability Dimensions: Physical: Infrastructure quality, building codes, location. Social: Age, income, disability, gender, acces
