Publikováno v: Earth Observing Systems XXVI.

The Multi-angle Imaging SpectroRadiometer (MISR) was launched in 1999 as part of NASA’s Terra satellite suite of instruments. Still operational, it makes use of observations from multiple view angles to retrieve aerosol abundance and particle prope

Publikováno v: Journal of Polymer Science, Part A: Polymer Chemistry, 38(3), 560-570. Wiley

Randomly branched bisphenol A polycarbonates (PCs) were prepared by interfacial polymerization methods to explore the limits of gel-free compositions available by the adjustment of various composition and process variables. A molecular weight distrib

Subsidence, mixing, and denitrification of Arctic polar vortex air measured during POLARIS

Publikováno v: Journal of Geophysical Research: Atmospheres. 104:26611-26623

We use the correlation between CH(sub 4) and N(sub 2)O as measured during the POLARIS campaign in spring 1997 to estimate the degree of mixing between descended air masses from the vortex and air masses from mid-latitudes.

Publikováno v: Journal of Geophysical Research: Atmospheres. 104:26419-26436

Observations made in the 1994 Antarctic vortex show that Cl y recovered completely into HCl following conversion of Cl y reservoir species to active radicals, and NO x constituted a 4-5 times higher fraction of NO y inside the vortex than outside. Me
