NASA's Dr. Ott Drives Greenhouse Gas Integration into Weather Forecasting
Scientists have made significant strides in integrating greenhouse gas data into weather forecasting systems. Dr. Ott, a NASA researcher, plays a crucial role in enhancing global models and providing vital information on greenhouse gases.
Over the past decade, the field of greenhouse gas modeling and observation has witnessed remarkable growth. Key breakthroughs include improved prior information, operational integration, and adaptive numerical methods. Dr. Ott finds the complexity of greenhouse gases intriguing, as they interact with various parts of the Earth system.
NASA's Orbiting Carbon Observatory (OCO) has contributed to this progress by delivering denser and higher-quality data, reducing biases between land and ocean measurements. However, despite these advances, GHG modeling remains one of the most challenging problems in Earth science due to small atmospheric gradients and uncertainty in vertical transport processes.
Dr. Ott envisions modeling centers supporting mitigation and adaptation efforts by providing actionable information on 10- to 30-year timescales. International cooperation is vital in this field, with initiatives like G3W fostering collaboration and open data sharing. The Task Team on Modelling (TT-G3W-Modelling) is transforming GHG modeling into a trusted operational, decision-supporting system.
