About the Role
UCAR is excited to announce the job opening for the Scientist IV role with the Cooperative Programs for the Advancement of Earth System Science (CPAESS) working with NOAA's Office of Model Development (OMD). This position will focus on enhancing coupled ocean and sea ice JEDI-based data assimilation system for the Global Forecasting System (GFS) by integrating critical marine observations. This may include transition from retrieved products to direct assimilation of Level 1b radiances for sea-surface-sensitive channels to improve atmosphere-ocean balance and sea surface temperature conditions, and integrating sea ice freeboard observations to address model biases and significantly improve sea-ice forecast skill.
CPAESS serves the Earth System Science community in three distinct areas of service. We partner with federal agencies and businesses to hire critical scientific staff enabling a more robust workforce. Through our scientific programs we seek to edify new research with our postdoctoral programs, our visiting scientist and internship programs, along with our interagency support programs. We also help build the Earth system science community by convening and managing summer schools and institutes, conferences, and advisory committees.

Office-based work typically involves maintaining concentration and focus on assigned tasks, extended periods of computer use, prolonged periods of sitting or standing, reviewing information on screens or documents, applying established protocols in a timely manner, communication with others regarding project assignments, and participating in meetings or collaborative activities.
This role and assigned projects may also include laboratory or field research activities that involve travel, work in variable environmental conditions such as weather and altitude (including extreme temperature changes, heat exposure, cold exposure, and other exposure to severe weather), and the use of specialized scientific instrumentation or equipment. Field assignments may occur in remote locations and may involve navigating uneven terrain, accessing elevated platforms, performing high-intensity manual tasks, or positioning oneself in constrictive spaces such as vehicles or aircraft.
Work may involve interaction with hazardous equipment and processes including electrical systems, heavy machinery, or chemicals that may lead to exposure to irritants or pollutants. Participation in workplace safety training is mandatory, and the use of personal protective equipment (PPE) may be required depending on the assignment.
Staff assigned to this role are expected to follow all applicable safety policies and procedures and must not pose a threat to the safety or wellbeing of themselves or others. Employees must be able to perform all mental and physical requirements necessary to carry out the responsibilities of the position and project assignments as outlined in the job description, which are considered essential functions of this position. All essential functions of the position must be performed with or without reasonable accommodation.
Preferred Qualifications
