Can semi-continuous carbon dioxide measurements taken from an instrument placed on top of a mobile light rail tram usefully improve urban emission estimates? Researchers, funded in part by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program, demonstrate not only that the measurements improve emission estimates but also that the measurements better capture spatial differences in emissions. 

A research team, funded in part by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program, participated in the 2018 WE-CAN field campaign and used resulting emission samples from 23 wildfires to better understand reactive nitrogen in wildfire plumes in order to improve air quality forecasts.

New study by researchers supported by CPO’s Climate Variability & Predictability (CVP) program investigates how the wet and dry seasons of the Maritime Continent impact daily precipitation cycles in the region. 

Funded in part by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate program, this study analyzed trends in two well-known precursors of ozone and their relationship to high ozone events in the Los Angeles basin over the last two decades. In particular, continued heat events will probably be associated with more high ozone events. 

A study funded by both CPO’s COM and MAPP programs shows the newest version of the NOAA-CIRES-DOE 20th Century Reanalysis Product produces useful estimates for past atmospheric variables as far back as 1806.
