Improving the ISBACC land surface model simulation of water and carbon fluxes and stocks over the Amazon forest
water and carbon fl uxes surface model simulation
2015/8/6
We evaluate the ISBACC (Interaction Soil Biosphere Atmosphere Carbon Cycle) land surface model
(LSM) over the Amazon forest, and propose a revised parameterization of photosynthesis, including new so...
DISCHARGE ESTIMATION FOR THE INVISIBLE AMAZON RIVER BRANCHES IN SAR IMAGES
Forestry Geomorphology Monitoring Visualization SAR
2015/7/30
Recently, desertification and degradation of water cycle by deforestation in the Amazon, South America, have become a serious
problem. In this study, it was attempted to estimate the discharge of th...
CHANGES IN THE LAND COVER AND LAND USE OF THE ITACAIúNAS RIVER WATERSHED, ARC OF DEFORESTATION, CARAJáS, SOUTHEASTERN AMAZON
Landsat, change detection, object based image analysis
2015/5/7
Human actions are changing the Amazon’s landscape by clearing tropical forest and replacing it mainly by pasturelands. The focus of this work is to assess the changes in the Itacaiúnas River watersh...
A COMPLEMENTARY USE OF INFORMATION FROM SPACE-BASED DINSAR AND FIELD MEASURING SYSTEMS FOR OPERATIONAL MONITORING PURPOSES IN OPEN PIT IRON MINES OF CARAJáS MINING COMPLEX (BRAZILIAN AMAZON REGION)
rock slope monitoring open pit iron mine
2015/5/7
Now spanning five simultaneous open-pit operations with exploration carried out through open pit benching, Carajás complex encompasses the world′s largest iron reserves. Open pit mining operations i...
Predicting the response of the Amazon rainforest to persistent drought conditions under current and future climates: a major challenge for global land surface models
major challenge global land surface models
2014/12/19
While a majority of global climate models project drier and longer dry seasons over the Amazon under higher CO2 levels, large uncertainties surround the response of vegetation to persistent droughts i...
Testing conceptual and physically based soil hydrology schemes against observations for the Amazon Basin
Testing conceptual physically based soil hydrology
2014/12/18
This study analyzes the performance of the two
soil hydrology schemes of the land surface model ORCHIDEE in estimating Amazonian hydrology and phenology for five major sub-basins (Xingu, Tapajó...
Disentangling the origins of branched tetraether lipids and crenarchaeol in the lower Amazon River: Implications for GDGT-based proxies
Disentangling the origins branched tetraether lipids crenarchaeol in the lower Amazon River Implications GDGT-based proxies
2014/4/2
To trace the origin of branched glycerol dialkyl glycerol tetraethers (brGDGTs), their distribution in soils and suspended particulate matter (SPM) of Amazonian rivers and floodplain lakes (va′ rzeas)...
Past terrestrial water storage (1980–2008) in the Amazon Basin reconstructed from GRACE and in situ river gauging data
water storage Amazon Basin GRACE
2011/2/9
Terrestrial water storage (TWS) composed of surface waters, soil moisture, groundwater and snow where appropriate, is a key element of global and continental water cycle. Since 2002, the Gravity Recov...

2010/11/30
Efficient data management is a key component in achieving good performance for scientific workflows in distributed environments. Workflow applications typically communicate data between tasks using fi...
Emission and dry deposition of accumulation mode particles in the Amazon Basin
mode particles the Amazon Basin
2010/11/3
Size-resolved vertical aerosol number fluxes of particles in the diameter range 0.25–2.5 μm were measured with the eddy covariance method from a 53 m high tower over the Amazon rain forest, 60 km NNW ...
Impact of Manaus City on the Amazon Green Ocean atmosphere: ozone production, precursor sensitivity and aerosol load
Manaus City the Amazon Green Ocean atmosphere ozone production precursor sensitivity aerosol load
2010/10/1
We used a Single Column Chemistry and Transport Model (SCM) to infer the urban pollution emission fluxes of Manaus City, implying observed mixing ratios of CO, NOx and VOC. The model can reproduce the...

North African dust the Bodélé depression the Amazon Basin
2010/8/16
This case study follows the dust events of 11–16 and 18–27 February 2008, from the emission in the Bodélé over West Africa (most likely with contribution from other dust sources in the region) the cro...
A comparison of dry and wet season aerosol number fluxes over the Amazon rain forest
dry and wet season aerosol number the Amazon rain forest
2010/3/31
Vertical number fluxes of aerosol particles and vertical fluxes of CO2 were measured with the eddy covariance method at the top of a 53 m high tower in the Amazon rain forest as part of the LBA (The L...
A contribution to understanding the turbidity behaviour in an Amazon floodplain
contribution turbidity behaviour Amazon floodplain
2010/2/22
Observations of turbidity provide quantitative information about water quality. However, the number of available in situ measurements for water quality determination is usually limited in time and spa...
