TITLE: New Insights into Volatile Organic Compounds from Urban and Biomass Burning Sources

PRESENTER: Joost de Gouw, University of Colorado Cooperative Institute for Research in Environmental Sciences

ABSTRACT: Volatile organic compounds (VOCs) in the atmosphere can react to form important pollutants such as ozone and secondary organic aerosol, and can also have direct effects on human health. In this seminar, I will present several new insights into the sources and chemistry of VOCs in urban air and in biomass burning emissions. New analyses of VOC measurements in the Los Angeles basin made during the NOAA CalNex study will be presented with a focus on separating the effects of emissions and chemical transformations. Output from the 3-D chemistry-transport model WRF-Chem is used to evaluate our methods for data analysis. Emissions of several compounds were higher than explained by motor vehicle sources, and are attributed to emissions from the use of volatile chemical products, such as cleaners, glues, coatings, solvents and personal care products. These fugitive sources are now estimated to be one of the largest sources of reactive VOCs in urban air. Measurements of VOCs in biomass burning emissions were made at the Fire Sciences Laboratory in Missoula, MT during the NOAA FIREX study. It will be shown how different processes such as distillation, and high- and low-temperature pyrolysis can explain the composition of VOC emissions for different fuels and phases of a burn. Finally, I will briefly discuss the development and characterization of new instrumentation for VOC measurements that have led to a new discovery phase in our science.

Title: Internal climate variability and potentially avoided impacts of the projected future regional sea level rise

Speaker: Aixue Hu, NCAR

Tuesday, January 23, 2018 - 11:00 a.m.
Mesa Lab, Main Seminar Room

Abstract:
Observational evidence points to a warming global climate accompanied by rising sea levels. This sea level rise (SLR) imposes significant impacts on island and coastal communities, especially compounded with storm surges. Here, by analyzing two sets of ensemble simulations from a climate model, we investigate potential SLR that may be avoided if a lower emission scenario is followed instead of business-as-usual one over the 21st Century and how it may be modulated by internal climate variability. Results show almost no statistically significant difference in thermosteric and dynamic SLR on both global and regional scales in the near-term between the two scenarios, but statistically significant SLR reduction for the global mean and many regions later in the century (2061-2080). However, there are regions where the reduction is insignificant, such as the Philippines and west of Australia, associated with ocean dynamics and intensified internal variability due to external forcing.

The city of Boulder has notified UCAR that the multi-use path east of Center Green will be closed for approximately two weeks beginning Monday, Jan. 22. The path, which crosses under Foothills Parkway, will be closed from Valmont Road to 47th Street.

The closure is necessary to allow the city's contractor to complete additional construction related to the ongoing Wonderland Creek Project. For more information on the project, see https://bouldercolorado.gov/flood/wonderland-creek-greenways-improvements.

Precipitation variability — the swing from dry to wet and back again — will continue to increase across the majority of the world's land area as the climate warms, according to a new study led by scientists at NCAR. The researchers expect precipitation variability to become greater from day to day, year to year, and even decade to decade.

Facing a medical challenge can be stressful enough without worrying whether you have the right diagnosis or the most effective treatment—especially when you consider that, according to the Institute of Medicine, it is likely that most of us will experience at least one diagnostic error in our lifetime.

UCAR is pleased to offer you the innovative medical benefit called Best Doctors.

Best Doctors is a better kind of second opinion service. It lets you get advice from the world’s leading physicians on everything from minor surgery and maternity challenges to more serious issues like cancer and heart disease. If you’re uncertain about a diagnosis or treatment, a Best Doctors clinician will take another look at your case and provide a confirmation or recommend a change.

What’s more: Best Doctors is 100% confidential and cost-free. It’s included in your benefits package and available at no charge to you and any of your dependents enrolled in the UCAR health plans – both Cigna and Kaiser throughout the United States. You don’t even have to make doctors’ appointments or travel. All of the Best Doctors services are provided over the phone or the Internet.

Please review the Best Doctors Web Page and Guide for additional information.
