Long-Term Field Observations Lead to New Insights in the Formation of Organic Aerosols 24 November 2020

Long-Term Field Observations Lead to New Insights in the Formation of Organic Aerosols

Research funded by two AC4 awards used observations from three long-term networks to update or “constrain” the chemical transport model mechanisms to more accurately represent the indirect formation and month-to-month variability of organic aerosol in the US southeast. 

Reducing Temperature Biases in Tropical Ocean Models 24 November 2020

Reducing Temperature Biases in Tropical Ocean Models

This work, funded by CPO’s Climate Variability & Predictability (CVP) program as part of NOAA’s contributions to the Tropical Pacific Observing System (TPOS) process studies, demonstrates how increasing the vertical resolution of ocean models can reduce commonly observed biases in the two regions.

Uncovering the Links between Surfactants, Sea Spray, and Tropical Cyclone Intensification 17 November 2020

Uncovering the Links between Surfactants, Sea Spray, and Tropical Cyclone Intensification

This study, supported by Climate Variability & Predictability, is the first to study how surfactants impact sea spray in regards to cylcones, the understanding of which could help improve model microphysics, leading to better forecasts that are more likely to capture rapid intensification of cyclones.

Predicting the Mass Concentration of Black Carbon in the Atmosphere 17 November 2020

Predicting the Mass Concentration of Black Carbon in the Atmosphere

Relying on both classical statistical techniques as well as new machine learning approaches, this project funded in part by Atmospheric Chemistry, Carbon Cycle, & Climate presents a new model for predicting the mass of black carbon in the atmosphere that can be used with inputs commonly collected at most long-term monitoring sites. 

Are Sea Surface Temperature Indices the Right Proxy for 100-year Trends in AMOC? 17 November 2020

Are Sea Surface Temperature Indices the Right Proxy for 100-year Trends in AMOC?

Research supported by the Climate Variability & Predictability program suggests that a common proxy for understanding AMOC trends, sea surface temperature indices, are not the best choice at the centennial scale, opening the door for new indices to be developed.
