A stochastic Forest Fire Model for future land cover scenarios assessment
Forest Fire Model future land scenarios assessment
2010/10/21
Land cover is affected by many factors including economic development, climate and natural disturbances such as wildfires. The ability to evaluate how fire regimes may alter future vegetation, and how...
Peering through the OH Forest: public release of sky-residual subtracted spectra for SDSS DR7
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/29
The Sloan Digital Sky Survey (SDSS) automated spectroscopic reduction pipeline provides >1.5 million intermediate resolution, R~2000, moderate signal-to-noise ratio (SNR), SNR~15, astronomical spectra...
Minimally Parametric Power Spectrum Reconstruction from the Lyman-alpha Forest
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
Current results from the Lyman alpha forest assume that the primordial power spectrum of density perturbations follows a simple power law form. We present the first analysis of Lyman alpha data to stu...
Observations of elevated formaldehyde over a forest canopy suggest missing sources from rapid oxidation of arboreal hydrocarbons

To better understand the processing of biogenic VOCs (BVOCs) in the pine forests of the US Sierra Nevada, we measured HCHO at Blodgett Research Station using Quantum Cascade Laser Spectroscopy (QCLS) ...
Composition and temporal behavior of ambient ions in the boreal forest
ambient ions the boreal forest
2010/9/21
A recently developed atmospheric pressure interface mass spectrometer (APi-TOF) measured the negative and positive ambient ion composition at a boreal forest site. As observed in previous studies, the...
Impact of climate change on water balance of forest sites in Rhineland-Palatinate, Germany
climate change water balance forest sites Rhineland-Palatinate
2010/9/10
It is expected that the biomass productivity of forest stands will be influenced by global climate change. In order to adapt forest management to this fact a model based approach was developed in coo...
Nanoparticles in boreal forest and coastal environment: a comparison of observations and implications of the nucleation mechanism
Nanoparticles boreal forest coastal environment the nucleation mechanism
2010/8/16
The detailed mechanism of secondary new particle formation in the atmosphere is still under debate. It is proposed that particle formation happens via activation of 1–2 nm atmospheric neutral molecula...
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...
Measurement of atmospheric nitrous acid at Bodgett Forest during BEARPEX2007
atmospheric nitrous acid Bodgett Forest BEARPEX2007
2010/8/16
Nitrous acid (HONO) is an important precursor of the hydroxyl radical (OH) in the lower troposphere. Understanding HONO chemistry, particularly its sources and contribution to HOx (=OH+HO2) production...
Turbulent exchange and segregation of HOx radicals and volatile organic compounds above a deciduous forest
