Catastrophic drainage of glacial Lake Missoula through the Columbia River Gorge, USA, produced some largest floods ever known. However, erosion gorge during flooding has not been quantified, hindering discharge reconstructions and our understanding landscape change by megafloods. Using a neural network field observations, we reconstructed topography found ?7.4 km3 rock was eroded from walls. Ac...

Abstract. Biomass burning aerosol is a major source of PM2.5, and significantly affects Earth's radiative budget. The magnitude its effect poorly quantified due to uncertainty in the optical properties formed from biomass burning. Using broadband cavity-enhanced spectrometer with recently increased spectral range (360–720 nm) coupled size-selecting inlet, we retrieve complex refractive indices ...
A study was conducted in Missoula, Montana to compare local pollen counts from 1978 with those measured nearly 30 years later in 2006 using two different measurement techniques (Durham gravimetric sampler and a Burkard volumetric sampler). Trends in peak pollen times measured during the spring, summer and autumn, respectively, were compared between the two years by Pearson's correlation and fre...
