Job Summary

The Cooperative Institute for Research in Environmental Sciences (CIRES) is seeking a Research Associate within the Physical Sciences Laboratory in Boulder, Colorado. The candidate will work alongside federal and university employees to conduct research within a collaborative team toward enhancing NOAA's hydrologic predictions at weather to seasonal timescales and contribute to advancing the use of machine learning methods for hydrologic prediction within this context. The project's outputs will serve a diverse community of users including fellow researchers in hydrometeorological forecasting communities, operational streamflow forecasting entities, and water resource decision-makers.

CU is an Equal Opportunity Employer and complies with all applicable federal, state, and local laws governing nondiscrimination in employment. We are committed to creating a workplace where all individuals are treated with respect and dignity, and we encourage individuals from all backgrounds to apply, including protected veterans and individuals with disabilities.

Who We Are

CIRES (https://cires.colorado.edu/) is an internationally recognized leader in innovative environmental science and research and is located at the University of Colorado Boulder. At CIRES, more than 900 environmental science professionals work to understand the dynamic Earth system, including people's relationship with the planet. CIRES has partnered with NOAA since 1967, and our areas of expertise include weather and climate, changes at Earth's poles, air quality and atmospheric chemistry, water resources, solid Earth sciences, and more. Our vision is to be instrumental in ensuring a sustainable future environment by advancing scientific and societal understanding of the Earth system.

The NOAA-Physical Sciences Laboratory (http://psl.noaa.gov/) (PSL) mission is to conduct scientific research to observe, understand, model, predict and forecast weather, water and climate extremes and their impacts. Our vision is an informed society that uses science-based environmental intelligence to effectively anticipate and respond to threats and opportunities related to weather, water, and climate extremes. Our research goals are as follows:

+ Rigorously characterize and predict weather, water, and climate extremes and their uncertainties to support NOAA's mission.

+ Develop new process-understanding, observing, and modeling capabilities to predict conditions associated with too much or too little water for early warning, preparedness, resource management, and adaptation.

+ Improve monitoring and prediction of weather, climate, and water conditions impacting marine resources.

What Your Key Responsibilities Will Be

+ Develop and/or apply machine learning based hydrologic modeling techniques and observations to improve ensemble streamflow forecasts (30%).

+ Establish data-processing workflows to obtain, manipulate, and visualize relevant observations and model output (15%).

+ Work with a team of scientists to improve skill, reliability, and interpretability of hydrometeorological forecasts for targeted applications (e.g., water availability, floods, droughts, etc.) (15%).

+ Conduct research to complement and enhance predictions from existing operational hydrological models. (10%).

+ Prepare and present results to scientific audiences and to stakeholders via journal publications, conference presentations, participation in professional societies, and/or user-group meetings. (15%).

+ Provide scientific and technical direction for experimental designs to test hypotheses and better understand limitations of machine learning methods for hydrologic simulation (10%).

+ Performs other relevant duties as necessary (Not to exceed 5%).
