TL;DR: As part of the ChArMEx project (Chemistry-Aerosol Mediterranean Experiment, http://charmex.ipsl.fr ), one year of continuous filter sampling was conducted from August 2012 to August 2013 at a rural (coastal) site in Algeria aiming to better document fine aerosol seasonal variability and chemical composition in the Southern parts of the Mediterranean.
Abstract: As part of the ChArMEx project (Chemistry-Aerosol Mediterranean Experiment, http://charmex.lsce.ipsl.fr
), one year of continuous filter sampling was conducted from August 2012 to August 2013 at a rural (coastal) site in Algeria aiming to better document fine aerosol seasonal variability and chemical composition in the Southern part of the Mediterranean. Over 350 filters have been collected, weighted, and analyzed for the main ions and organic and elemental carbon. The obtained mass concentrations varied between 2.5 and 50.6 μg/m3 for PM2.5. The annual modulations of PM2.5 showed higher concentrations in the end summer 2012 and the early summer 2013 (28.50 μg/m3 in August 2012, 20.23 μg/m3 in September 2012, 20.19 μg/m3 in July 2013, and 17.88 μg/m3in August 2013). The particulate organic matter (POM) presented the greatest contribution (50%), followed by the secondary inorganic aerosols (SIA, 27%). The average organic carbon OC concentrations ranged from 1.66 to 6.05 μgC/m3. The average elemental carbon EC concentrations ranged from 0.92 to 3.49 μgC/m3 and contributed 7% of the PM2.5 mass to Bou-Ismail. The average value of the OC /EC ratio was close to 5.1 in Bou-Ismail, and was close to that found in Finokalia 4 (Greece 2004, 2006) but was lower than that of Montseny 11 (Spain 2002–2007) Western Mediterranean Basin (WMB). The concentrations of water-soluble organic carbon WSOC in the PM2.5 ranging from 0.66 to 3.70 μg/m3 recorded the minimum level in March 2013, and the maximum level in August 2012, with an average of 2.02 μg/m3.

TL;DR: In this article, the authors present the first incorporation of the Common Representative Intermediates version 2.2 tropospheric chemistry mechanism, CRI v2.2, into the global chemistry-climate United Kingdom Chemistry and Aerosols (UKCA) model to give the CRI-Strat-2 fixmemechanism.
Abstract: . We present the first incorporation of the Common Representative
Intermediates version 2.2 tropospheric chemistry mechanism, CRI v2.2,
combined with stratospheric chemistry, into the global chemistry–climate
United Kingdom Chemistry and Aerosols (UKCA) model to give the CRI-Strat 2
mechanism. A rigorous comparison of CRI-Strat 2 with the earlier version,
CRI-Strat, is performed in UKCA in addition to an evaluation of three
mechanisms, CRI-Strat 2, CRI-Strat and the standard UKCA chemical mechanism,
StratTrop v1.0, against a wide array of surface and airborne chemical data. CRI-Strat 2 comprises a state-of-the-art isoprene scheme, optimized against
the Master Chemical Mechanism v3.3.1, which includes isoprene peroxy radical isomerization,
HO x recycling through the addition of photolabile hydroperoxy aldehydes
(HPALDs), and isoprene epoxy diol (IEPOX) formation. CRI-Strat 2 also features updates to several
rate constants for the inorganic chemistry, including the reactions of
inorganic nitrogen and O(1D) . The update to the isoprene chemistry in CRI-Strat 2 increases OH over the
lowest 500 m in tropical forested regions by 30 % –50 % relative to
CRI-Strat, leading to an improvement in model–observation comparisons for
surface OH and isoprene relative to CRI-Strat and StratTrop. Enhanced
oxidants also cause a 25 % reduction in isoprene burden and an increase in
oxidation fluxes of isoprene and other biogenic volatile organic compounds
(BVOCs) at low altitudes with likely impacts on subsequent aerosol formation, atmospheric
lifetime, and climate. By contrast, updates to the rate constants of O(1D) with its main
reactants relative to CRI-Strat reduces OH in much of the free troposphere,
producing a 2 % increase in the methane lifetime, and increases the
tropospheric ozone burden by 8 % , primarily from reduced loss via
O(1D)+H2O . The changes to inorganic nitrogen reaction rate
constants increase the NO x burden by 4 % and shift the distribution
of nitrated species closer to that simulated by StratTrop. CRI-Strat 2 is suitable for multi-decadal model integrations and the
improved representation of isoprene chemistry provides an opportunity to
explore the consequences of HO x recycling in the United Kingdom Earth
System Model (UKESM1). This new mechanism will enable a re-evaluation of the
impact of BVOCs on the chemical composition of the atmosphere and further probe
the feedback between the biosphere and the climate.

TL;DR: In this article, the authors consider the problem of limiting what levels of insight that can be derived from a small number of scenarios, modelled with proprietary models and closed data-sets.

01 Mar 2010TL;DR: In this paper, laser-induced infrared photocarrier radiometry (PCR) was used to characterize industrial polycrystalline silicon solar cells and the ac photovoltage was measured simultaneously with the PCR signal.
Abstract: Laser-induced infrared photocarrier radiometry (PCR) was used to characterize industrial polycrystalline silicon solar cells. The ac photovoltage was measured simultaneously with the PCR signal. The PCR and ac photovoltage signals were investigated as functions of modulation frequency, excitation intensity, external dc illumination and load resistance. The interrelation and interpretation of PCR signal, ac photovoltage and static (dc) electrical parameters of solar cells are discussed.
