Postdoc Researcher (Hydrological Modeling)

Boulder, CO, United States 🇺🇸

This is a full-time, 2-year term position with possibility of an extension.  Initial consideration will be given to applications received prior to March 2nd 2017. Thereafter, applications will be reviewed on an as-needed basis.

NCAR – Research Applications Laboratory (RAL) – Hydrometeorology Applications Program (HAP)

No relocation package is offered for this position.

UCAR/NCAR will sponsor a work visa to fill this position.

Where You Will Work

Located in Boulder, Colorado, the National Center for Atmospheric Research (NCAR) is one of the world’s premier scientific institutions, with an internationally recognized staff and research program dedicated to advancing knowledge, providing community-based resources, and building human capacity in the atmospheric and related sciences

What You Will Do

NCAR is searching for a Postdoctoral Researcher whom will conduct research on the application of hydrologic models spanning a range of complexity within two contexts: (1) medium-range ensemble streamflow prediction; and (2) characterization of uncertainties and sensitivities in flood frequency estimation.  The overarching goal of the position is to investigate the sensitivity and performance of a range of ensemble-based approaches for quantifying and predicting hydrologic extremes.  The research will involve hydrologic model implementation (e.g., the Structure for Unifying Multiple Modeling Alternatives, SUMMA;, as well as other simpler modeling frameworks) and diagnostic hydrologic model evaluation across a large number of watersheds in the western US.

  • Implement a large-ensemble approach across hydrologic model structures, parameters, and initial conditions to more comprehensively understand flood frequencyuncertainties and sensitivities across watersheds.
  • Implement and assess a range of medium-range hydrologic prediction strategies employing ensemble meteorological inputs and forecasts and watershed models ofvarying complexity.
  • Participate in research development with internal and external collaborators across disciplines, including contribution to research funding proposals.
  • Communicate research results through publication in peer-reviewed journals, meeting proceedings, and presentations at scientific meetings.

What You Need

  • PhD degree in hydrologic sciences or closely related discipline.
  • Experience in physically-oriented hydrologic modeling on UNIX-based platforms.
  • Demonstrated record of research and publication.
  • In-depth knowledge of process-based hydrologic modeling.
  • Skill in developing and implementing statistical and simulation techniques (e.g., meteorological forcing, hydrologic model parameter estimation,parameter sensitivity analyses, etc).
  • Ability to conduct graphical and statistical analyses and post-processing of model output.
  • Ability to establish and maintain a nationally recognized publication record.
  • Ability to participate in and interact productively with hydrologic analysis and prediction groups, statisticians and hydrometeorological scientistsat NCAR and among the hydrometeorological forecasting community. 
  • Strong skills in written and oral communication of research results, including in an interdisciplinary context.  
  • Technical/computational skills:
    • Strong competence with data, program and file management in UNIX
    • Strong competence in FORTRAN
    • Demonstrated skill in working with large and heterogeneous datasets
    • Demonstrated skill in managing large computationally intensive model simulations
    • Competence with scripting languages such as Python and UNIX shell
    • Competence with analysis and scripting in R, Matlab, or similar analysis language
    • Familiarity with GIS or GIS-equivalent (e.g., gdal)
    • Familiarity with code sharing environments such as Github
    • Familiarity with super-computing environments (e.g., computing clusters)
