CIRES/NOAA PSL Postdoctoral Associate on Characterizing the Impact of Model Error and Bias on Subseasonal-to-Seasonal Forecast Skill Using a Hybrid Numerical Model-Machine Learning Approach
Posting Close Date:
The issue of improving subseasonal-to-seasonal forecast skill inherently relies on enhancing our understanding of how model bias and forecast error associated with the simulation of specific dynamical modes of climate degrade forecasts. The University of Colorado's Cooperative Institute for Research in Environmental Sciences (CIRES) and the Physics Sciences Laboratory (PSL) at the NOAA Earth System Research Lab in scenic Boulder, Colorado, seeks an enthusiastic and capable postdoc to help us better understand these interactions in the context of temperature and precipitation forecasts over North America on subseasonal timescales. The hire will work on the development of several machine learning-based dynamical climate mode filtering techniques that will be subsequently integrated into the existing NOAA Physical Science Laboratory (PSL) Unified Forecast System (UFS) “nudging” framework, to determine the relative contribution of ENSO, the MJO, and various stratospheric processes to model errors and biases. The candidate will use additional empirical modeling techniques (e.g., Markov models) trained on UFS model output in order to determine which dynamical modes contribute most to forecast lead-dependent tropical errors and downstream extratropical errors, aiming to develop UFS model diagnostics and/or post-processing techniques for forecast improvement.
The candidate should have excellent technical and communication skills and be comfortable working in a team environment. This is a two-year position with the possibility of extension to a third year based on performance and achievement of project goals and the availability of funding.
The University of Colorado Boulder is committed to building a culturally diverse community of faculty, staff, and students dedicated to contributing to an inclusive campus environment. We are an Equal Opportunity employer, including veterans and individuals with disabilities.
Who We Are Cooperative Institute for Research in Environmental SciencesThe Cooperative Institute for Research in Environmental Sciences (CIRES)
is an internationally recognized leader in innovative environmental science and research and is located at the University of Colorado Boulder. At CIRES, the Cooperative Institute for Research in Environmental Sciences, more than 800 environmental scientists work to understand the dynamic Earth system, including people’s relationship with the planet. CIRES is a partnership of NOAA and the University of Colorado Boulder, and our areas of expertise include weather and climate, changes at the Earth’s poles, air quality and atmospheric chemistry, water resources, and solid Earth sciences. Our vision is to be instrumental in ensuring a sustainable future environment by advancing scientific and societal understanding of the Earth system.Physical Sciences Laboratory
Our mission is to conduct scientific research to observe, understand, model, predict and forecast weather, water and climate extremes and their impacts. 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.
