BABAR-ERI: Black Array of Broadband Absolute Radiometers - Earth Radiation Imager

September 22, 2023
Author(s)
Chris Yung, Cameron Straatsma, Nathan Tomlin, David Harber, Odele Coddington, John H. Lehman, Michelle Stephens
BABAR-ERI is being developed for a CubeSat capable of imaging the Earth's outgoing longwave radiation with a 1 km ground sample distance (GSD) using a push-broom imager. The detector is a silicon micromachined 32-pixel linear array of electrical

… ground state X 1 Σ + (υ 11 = 0) by storing a CH + beam at 7.1 MeV in the heavy-ion storage ring TSR for up to 30 s, … spacings we determine the dissociation energy D0 = (32946.7 1.1) cm -1 (with respect to the lower fine-structure limit) …

The persistence of smoke VOCs indoors: partitioning, surface cleaning, and air cleaning in a smoke-contaminated house

October 13, 2023
Author(s)
Jienan Li, Michael F. Link, Shubhrangshu Pandit, Marc Webb, Cholaphan Deeleepojananan, Kathryn Mayer, Lauren Garofalo, Katelyn Rediger, Dustin Poppendieck, Stephen Zimmerman, Marina Vance, Vicki Grassian, Glenn Morrison, Barbara Turpin, Delphine Farmer
Wildfires are increasing in frequency, raising concerns that smoke can permeate indoor environments and expose people to chemical air contaminants. To study smoke transformations in indoor environments and evaluate mitigation strategies, we added smoke to
