OU-Led Study Links Deep-Time Dust with Major Impacts on Carbon Cycling
OU-Led Deep-Time Dust Carbon Cycling
2015/12/7
A University of Oklahoma-led study links vast amounts of iron-rich dust deposits from the late Paleozoic period of 300 million years ago with implications for major ecosystem fertilization and a massi...
A Bayesian method for the analysis of deterministic and stochastic time series
methods:statistical brown dwarf
2012/11/23
I introduce a general, Bayesian method for modelling univariate time series data assumed to be drawn from a continuous, stochastic process. The method accommodates arbitrary temporal sampling, and tak...

2016/3/25
Air quality data collected at 8 monitoring stations located in the central Taiwan Air Quality Total Quantity Control
District were analyzed using multivariate statistical factor analyses. Based on th...
Characterization of the sources and processes of organic and inorganic aerosols in New York city with a high-resolution time-of-flight aerosol mass apectrometer
organic and inorganic aerosols New York city a high-resolution time-of-flight aerosol mass apectrometer
2011/2/25
Submicron aerosol particles (PM1) were measured in-situ using a High-Resolution Time-of-Flight Aerosol Mass Spectrometer during the summer 2009 Field Intensive Study at Queens College in New York, NY....
Global distributions of methanol and formic acid retrieved for the first time from the IASI/MetOp thermal infrared sounder
formic acid the IASI/MetOp thermal infrared sounder
2011/2/24
Methanol (CH3OH) and formic acid (HCOOH) are among the most abundant volatile organic compounds present in the atmosphere. In this work, we derive the global distributions of these two organic species...

Ozone carbon monoxide nitrogen oxides four alpine GAW mountain stations central Europe
2010/12/28
Long-term, ground based in-situ observations of ozone (O3) and its precursor gases nitrogen dioxide (NO2) and carbon monoxide (CO) from the four sites Hohenpeissenberg and Zugspitze (D), Sonnblick (A)...
Polar organic marker compounds in atmospheric aerosols during the LBA-SMOCC 2002 biomass burning experiment in Rondônia, Brazil: sources and source processes, time series, diel variations and size distributions
Polar organic marker atmospheric aerosols the LBA-SMOCC 2002 biomass burning experiment time series diel variations size distributions
2010/10/11
Measurements of polar organic marker compounds were performed on aerosols that were collected at a pasture site in the Amazon basin (Rondônia, Brazil) using a high-volume dichotomous sampler (HV...
Sensitivity of ensemble Lagrangian reconstructions to assimilated wind time step resolution
ensemble Lagrangian reconstructions wind time step resolution
2010/8/12
We study the impact of temporal and spatial resolution and changes in modelled meteorological winds in the context of diffusive ensemble Lagrangian reconstructions. In situ tracer measurements are mod...
Toward real-time measurement of atmospheric mercury concentrations using cavity ring-down spectroscopy
real-time measurement atmospheric mercury concentrations cavity ring-down spectroscopy
2010/8/12
Cavity ring-down spectroscopy (CRDS) is a direct absorption technique that utilizes path lengths up to multiple kilometers in a compact absorption cell and has a significantly higher sensitivity than ...

Time-dependent limb-darkening calibration solar occultation instruments
2010/1/18
Solar occultation has proven to be a reliable technique for the measurement of atmospheric constituents in the stratosphere. NASA's Stratospheric Aerosol and Gas Experiments (SAGE, SAGE II, and SAGE I...
VOC measurements within a boreal forest during spring 2005: on the occurrence of elevated monoterpene concentrations during night time intense particle concentration events
VOC measurements boreal forest monoterpene concentrations
2009/11/19
In this study we present measurements of selected trace gases and aerosols made in a boreal forest during the BACCI-QUEST IV intensive field campaign in Hyytiälä, Finland in April 2005. Spri...
Lagrangian structures in time-periodic vortical flows
Lagrangian structures time-periodic vortical flows
2009/11/9
The Lagrangian trajectories of fluid particles are experimentally studied in an oscillating four-vortex velocity field. The oscillations occur due to a loss of stability of a steady flow and result in...
