2010/8/12
The chemical and physical differences of secondary organic aerosol (SOA) formed at select isothermal temperatures (278 K, 300 K, and 313 K) are explored with respect to density, particle volatility, p...
The effect of misleading surface temperature estimations on the sensible heat fluxes at a high Arctic site – the Arctic Turbulence Experiment 2006 on Svalbard (ARCTEX-2006)
misleading surface temperature sensible heat fluxes ARCTEX
2010/1/18
The observed rapid climate warming in the Arctic requires improvements in permafrost and carbon cycle monitoring, accomplished by setting up long-term observation sites with high-quality in-situ measu...
Direct measurements of the effect of biomass burning over the Amazon on the atmospheric temperature profile
biomass burning Amazon atmospheric temperature profile
2009/11/19
Aerosols suspended in the atmosphere interact with solar radiation and clouds, thus change the radiation energy fluxes in the atmospheric column. In this paper we measure changes in the atmospheric te...
Discriminating low frequency components from long range persistent fluctuations in daily atmospheric temperature variability
