Impact of biomass burning aerosol on the monsoon circulation transition over Amazonia  

DOE Green Energy (OSTI)

Ensemble simulations of a regional climate model (RegCM3) forced by aerosol radiative forcing suggest that biomass burning aerosols can work against the seasonal monsoon circulation transition, thus re-enforce the dry season rainfall pattern for Southern Amazonia. Strongly absorbing smoke aerosols warm and stabilize the lower troposphere within the smoke center in southern Amazonia (where aerosol optical depth > 0.3). These changes increase the surface pressure in the smoke center, weaken the southward surface pressure gradient between northern and southern Amazonia, and consequently induce an anomalous moisture divergence in the smoke center and an anomalous convergence occurs in northwestern Amazonia (5°S-5°N, 60°W-40 70°W). The increased atmospheric thermodynamic stability, surface pressure, and divergent flow in Southern Amazonia may inhibit synoptic cyclonic activities propagated from extratropical South America, and re-enforce winter-like synoptic cyclonic activities and rainfall in southeastern Brazil, Paraguay and northeastern Argentina.

Evaluation of the carbon content of aerosols from the burn- ing of biomass in the Brazilian Amazon using thermal, op- tical and thermal-optical analysis methods  

DOE Green Energy (OSTI)

Aerosol samples were collected at a pasture site in the Amazon Basin as part of the project LBA-SMOCC-2002 (Large-Scale Biosphere-Atmosphere Experiment in Amazonia - Smoke Aerosols, Clouds, Rainfall and Climate: Aerosols from Biomass Burning Perturb Global and Regional Climate). Sampling was conducted during the late dry season, when the aerosol composition was dominated by biomass burning emissions, especially in the submicron fraction. A 13-stage Dekati low-pressure impactor (DLPI) was used to collect particles with nominal aerodynamic diameters (D{sub p}) ranging from 0.03 to 0.10 m. Gravimetric analyses of the DLPI substrates and filters were performed to obtain aerosol mass concentrations. The concentrations of total, apparent elemental, and organic carbon (TC, EC{sub a}, and OC) were determined using thermal and thermal-optical analysis (TOA) methods. A light transmission method (LTM) was used to determine the concentration of equivalent black carbon (BC{sub e}) or the absorbing fraction at 880 nm for the size-resolved samples. During the dry period, due to the pervasive presence of fires in the region upwind of the sampling site, concentrations of fine aerosols (D{sub p} < 2.5 {mu}m: average 59.8 {mu}g m{sup -3}) were higher than coarse aerosols (D{sub p} > 2.5 {mu}m: 4.1 {mu}g m{sup -3}). Carbonaceous matter, estimated as the sum of the particulate organic matter (i.e., OC x 1.8) plus BC{sub e}, comprised more than 90% to the total aerosol mass. Concentrations of EC{sub a} (estimated by thermal analysis with a correction for charring) and BCe (estimated by LTM) averaged 5.2 {+-} 1.3 and 3.1 {+-} 0.8 {mu}g m{sup -3}, respectively. The determination of EC was improved by extracting water-soluble organic material from the samples, which reduced the average light absorption {angstrom} exponent of particles in the size range of 0.1 to 1.0 {mu}m from > 2.0 to approximately 1.2. The size-resolved BC{sub e} measured by the LTM showed a clear maximum between 0.4 and 0.6 m in diameter. The concentrations of OC and BC{sub e} varied diurnally during the dry period, and this variation is related to diurnal changes in boundary layer thickness and in fire frequency.

Aerosol samples were collected at a pasture site in the Amazon Basin as part of the project LBA-SMOCC-2002 (Large-Scale Biosphere-Atmosphere Experiment in Amazonia - Smoke Aerosols, Clouds, Rainfall and Climate: Aerosols from Biomass Burning Perturb Global and Regional Climate). Sampling was conducted during the late dry season, when the aerosol composition was dominated by biomass burning emissions, especially in the submicron fraction. A 13-stage Dekati low-pressure impactor (DLPI) was used to collect particles with nominal aerodynamic diameters (D{sub p}) ranging from 0.03 to 0.10 m. Gravimetric analyses of the DLPI substrates and filters were performed to obtain aerosol mass concentrations. The concentrations of total, apparent elemental, and organic carbon (TC, EC{sub a}, and OC) were determined using thermal and thermal-optical analysis (TOA) methods. A light transmission method (LTM) was used to determine the concentration of equivalent black carbon (BC{sub e}) or the absorbing fraction at 880 nm for the size-resolved samples. During the dry period, due to the pervasive presence of fires in the region upwind of the sampling site, concentrations of fine aerosols (D{sub p} aerosols (D{sub p} > 2.5 {mu}m: 4.1 {mu}g m{sup -3}). Carbonaceous matter, estimated as the sum of the particulate organic matter (i.e., OC x 1.8) plus BC{sub e}, comprised more than 90% to the total aerosol mass. Concentrations of EC{sub a} (estimated by thermal analysis with a correction for charring) and BCe (estimated by LTM) averaged 5.2 {+-} 1.3 and 3.1 {+-} 0.8 {mu}g m{sup -3}, respectively. The determination of EC was improved by extracting water-soluble organic material from the samples, which reduced the average light absorption {angstrom} exponent of particles in the size range of 0.1 to 1.0 {mu}m from > 2.0 to approximately 1.2. The size-resolved BC{sub e} measured by the LTM showed a clear maximum between 0.4 and 0.6 m in diameter. The concentrations of OC and BC{sub e} varied diurnally during the dry period, and this variation is related to diurnal changes in boundary layer thickness and in fire frequency.

Foreign Influences and Consequences on the Nuragic Culture of Sardinia  

E-Print Network (OSTI)

Although it is accepted that Phoenician colonization occurred on Sardinia by the 9th century B.C., it is possible that contact between Sardinia?s indigenous population and the Levantine region occurred in the Late Bronze Age (LBA). Eastern LBA goods found on the island are copper oxhide ingots and Aegean pottery. Previously, it has been suggested that Mycenaeans were responsible for bringing the eastern goods to Sardinia, but the presence of Aegean pottery shards does not confirm the presence of Mycenaean tradesmen. Also, scholars of LBA trade have explained the paucity of evidence for a Mycenaean merchant fleet. Interpretations of two LBA shipwrecks, Cape Gelidonya and Uluburun, indicate that eastern Mediterranean merchants of Cypriot or Syro-Canaanite origin, transported large quantities of oxhide ingots from the Levant towards the west. It remains possible that similar itinerant merchants conducted ventures bringing eastern goods to Sardinia while exploring the western Mediterranean. Trade in eastern goods may have stimulated the advancement that occurred in Nuragic culture in the LBA, resulting in the emergence of an elite social stratum in the Nuragic society. Archaeological evidence, such as elitist burials and increasingly complex architecture, supports the idea of cultural change due to internal competition. This „peer-polity? effect may have been incited because of limited accessibility to the exotic eastern goods and the „ownership? to the rights of this exchange.

Sic et non en el Libro de buen amor  

E-Print Network (OSTI)

This thesis studies the concept of sic et non (the paradox of systematically acting in a way which contradicts one's beliefs or of simultaneously holding two contradictory beliefs) in the LBA and its cultural milieu, demonstrating how the author and his work reveal themselves to be products of their particular time and place. After setting forth the philosophical foundation of the concept, it goes on to show how sic et non permeates the society, demonstrating how the antagonism between the two-swords--the ecclesiastic and the civil authorities--has a profound effect on the way of life and on the beliefs of the intellectuals and of the ruling classes. Spain is shown to be just as European as the societies which produced Chaucer or Boccaccio. Special attention is devoted to the relations between the sexes, as this is pertinent to the study of the LBA. Sic et non manifests itself in a meaning not always easy to apprehend as well as in a literary form marked by a duality of significants which do not appear to always point to the same signifies. This instability--shifting reality--is a refection of the everyday reality observed by the writers. An analysis of that reality should explain the simultaneous preaching of been amor and appealing presentation of loco amor. The protagonist is not a hypocrite but, rather, one aware of what goes on around him. That awareness determines the form as well as the meaning, even if we cannot agree about what the latter is. In order for the audience to capture the subtleties of which the author warns (LBA 1988 65, 67, 68, 70), it, too, must share this awareness. Whether or not we identify him with the author, the protagonist is the conscious artist who values his art for its own sake.

Ela atua como uma das fontes indispensáveis de calor para a atmosfera global por meio da evaporação do vapor d'água na superfície e liberação de calor na média e alta troposfera pelo calor latente de condensação em nuvens convectivas tropicais. A evaporação ao longo do ano é de aproximadamente 3 a 3,5 mm d -1 . Mas, em regiões de savana na fronteira com a floresta amazônica, a evaporação

Challenges to estimating carbon emissions from tropical deforestation  

E-Print Network (OSTI)

An accurate estimate of carbon fluxes associated with tropical deforestation from the last two decades is needed to balance the global carbon budget. Several studies have already estimated carbon emissions from tropical deforestation, but the estimates vary greatly and are difficult to compare due to differences in data sources, assumptions, and methodologies. In this paper, we review the different estimates and datasets, and the various challenges associated with comparing them and with accurately estimating carbon emissions from deforestation. We performed a simulation study over legal Amazonia to illustrate some of these major issues. Our analysis demonstrates the importance of considering land-cover dynamics following deforestation, including the fluxes from reclearing of secondary vegetation, the decay of product and slash pools, and the fluxes from regrowing forest. It also suggests that accurate carbon-flux estimates will need to consider historical land-cover changes for at least the previous 20 years. However, this result is highly sensitive to estimates of the partitioning of cleared carbon into instantaneous burning vs. long-timescale slash pools. We also show that carbon flux estimates based on ‘committed flux ’ calculations, as used by a few studies, are not comparable with the ‘annual balance ’ calculation method used by other studies.

Carbon emissions and sequestration in forests: Case studies from seven developing countries  

SciTech Connect

Deforestation in Brazilian Amazonia in 1990 was releasing approximately 281--282 X 10{sup 6} metric tons (MT) of carbon on conversion to a landscape of agriculture, productive pasture, degraded pasture, secondary forest and regenerated forest in the proportions corresponding to the equilibrium condition implied by current land-use patterns. Emissions are expressed as committed carbon,'' or the carbon released over a period of years as the carbon stock in each hectare deforested approaches a new equilibrium in the landscape that replaces the original forest. To the extent that deforestation rates have remained constant, current releases from the areas deforested in previous years will be equal to the future releases from the areas being cleared now. Considering the quantities of carbon dioxide, carbon monoxide, methane, nitrous oxide, NO{sub x} and non-methane hydrocarbons released raises the impact by 22--37%. The relative impact on the greenhouse effect of each gas is based on the Intergovernmental Panel on Climate Change (IPCC) calculations over a 20-year time period (including indirect effects). The six gases considered have a combined global warming impact equivalent to 343 to 386 million MT of C0{sub 2}-equivalent carbon, depending on assumptions regarding the release of methane and other gases from the various sources such as burning and termites. These emissions represent 7--8 times the 50 million MT annual carbon release from Brazil's use of fossil fuels, but bring little benefit to the country. Stopping deforestation in Brazil would prevent as much greenhouse emission as tripling the fuel efficiency of all the automobiles in the world. The relatively cheap measures needed to contain deforestation, together with the many complementary benefits of doing so, make this the first priority for funds intended to slow global warming.
