CIRES / NOAA Physical Sciences Laboratory, Research Associate focused on the Impact of Snow in Streamflow and Water Resource Predictions

CIRES 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 (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.

• Develop and/or apply hydrologic modeling techniques and observations to further understanding of seasonal snowpack, streamflow, and related processes (30%).
• Establish data-processing workflows to obtain, manipulate, and visualize relevant observations and model output (20%).
• 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%).
• Provide scientific and technical direction for experimental designs to test hypothesis around snow, streamflow, and other related processes (20%).
• Prepare and present results to scientific audiences and to partners via journal publications, conference presentations, and/or user-group meetings (10%).
• Performs other relevant duties as necessary (Not to exceed 5%).

• This position will be rostered in CIRES at the University of Colorado Boulder but will be physically situated in the NOAA laboratory facility at the David Skaggs Research Center, 325 Broadway, Boulder, CO 80305.

• This position can accommodate a hybrid work modality.
• This position does not offer relocation.
• An opportunity to work on the next-generation hydrologic forecast models and produce information on water risks and opportunities to support water resource decisions and management.
• CIRES and the University of Colorado boulder offer a robust training curriculum, opportunities for professional development and a Mentorship Program.
• Boulder is a vibrant community with access to mountain parks, dog parks, miles of trails, rivers, lakes, cafes, restaurants, boutiques, theaters, museums, and sports venues.
• As an employee at CU Boulder, you will have free access to the regional public transit system, an outstanding network of buses, and light rail systems that service Boulder and connect to Denver, the Denver airport, and surrounding communities.

• A PhD in Watershed Science, Hydrology, Civil Engineering, or a related discipline.
• 2 years post-PhD experience.
• Hands-on knowledge or familiarity with state-of-the-art hydrologic models.
• Familiarity with state-of-the-art observational snow datasets in the western US.
• Knowledge of ways to estimate snow drought and the implications of snow processes for streamflow estimation.
• Ability to work and communicate effectively within a team environment and to facilitate communications across multiple teams and multiple organizational units.
• Experience using Linux and developing structured code in Python, R, and/or shell scripting.

• Expertise in hydrometeorology, hydroclimatology, statistics, or data science.
• Hands-on knowledge or familiarity with state-of-the-art snow datasets.
• Interest in hydrometeorological forecasting.
• Ability to work and communicate effectively within a team environment and to facilitate communications across multiple teams and multiple organizational units.
