Effects of lightning and other meteorological factors on fire activity in the North American boreal forest: implications for fire weather forecasting
meteorological factors fire activity the North American boreal forest fire weather forecasting
2010/8/16
The effects of lightning and other meteorological factors on wildfire activity in the North American boreal forest are statistically analyzed during the fire seasons of 2000–2006 through an integratio...
Factors influencing zooplankton size structure at contrasting temperatures in coastal shallow lakes: Implications for effects of climate change
Factors influencing zooplankton size structure at contrasting temperatures in coastal shallow lakes: Implications for effects of climate change
2014/4/17
We assessed the importance of temperature, salinity, and predation for the size structure of zooplankton and provided insight into the future ecological structure and function of shallow lakes in a wa...
Measured and modeled humidification factors of fresh smoke particles from biomass burning: role of inorganic constituents
humidification factors fresh smoke particles biomass burning inorganic constituents
2010/8/16
During the 2006 FLAME study (Fire Laboratory at Missoula Experiment), laboratory burns of biomass fuels were performed to investigate the physico-chemical, optical, and hygroscopic properties of fresh...
Factors influencing the contribution of ion-induced nucleation in a boreal forest, Finland
ion-induced nucleation a boreal forest Finland
2010/8/12
We present the longest series of measurements so far (2 years and 7 months) made with an Ion-DMPS at the SMEAR II measurement station in Hyytiälä, Southern Finland. We show that the classifi...
Particle number, particle mass and NOx emission factors at a highway and an urban street in Copenhagen
Particle number particle mass NOx emission factors an urban street Copenhagen
2010/8/12
This paper presents measurements of traffic-generated gas and particle pollution at two sites, one near a major highway and one near a busy urban street in Copenhagen, Denmark. Both sites were equippe...
Measured and predicted aerosol light scattering enhancement factors at the high alpine site Jungfraujoch
aerosol light enhancement factors high alpine site Jungfraujoch
2010/3/16
Ambient relative humidity (RH) determines the water content of atmospheric aerosol particles and thus has an important influence on the amount of visible light scattered by particles. The RH dependenc...
Biomass burning aerosol emissions from vegetation fires: particle number and mass emission factors and size distributions
Biomass burning aerosol vegetation fires mass emission factors
2010/2/21
Aerosol emissions from vegetation fires have a large impact on air quality and climate. In this study, we use published experimental data and different fitting procedures to derive dynamic particle nu...
Fractional release factors of long-lived halogenated organic compounds in the tropical stratosphere
Fractional release factors halogenated organic compounds tropical stratosphere
2010/2/21
Fractional release factors (FRFs) of organic trace gases are time-independent quantities that influence the calculation of Global Warming Potentials and Ozone Depletion Potentials. We present the firs...
Deciphering the effect of climate change and separating the influence of confounding factors in sediment core records using additive models
Deciphering the effect of climate change separating the influence of confounding factors sediment core records using additive models
2014/4/17
We describe a new approach to modeling sediment core records, one that uses additive models (AMs) incorporating a serial correlation structure to model residual autocorrelation. Species assemblages, f...

2009/11/13
Simulations based on random multiplicative cascade models are used to investigate the uncertainty in estimates of parameters characterizing the multiscaling nature of rainfall time series. The princip...
Factors controlling contrail cirrus optical depth
Factors controlling contrail cirrus optical depth
2009/9/2
Aircraft contrails develop into contrail cirrus by depositional growth and sedimentation of ice particles and horizontal spreading due to wind shear. Factors controlling this development include tempe...
