Climate change is profoundly transforming the carbon-rich Arctic tundra landscape, potentially moving it from a carbon sink to a carbon source by increasing the thickness of soil that thaws on a seaso...
Assimilation of surface NO2 and O3 observations into the SILAM chemistry transport model
surface NO2 chemistry transport model
2015/3/5
This paper describes the assimilation of trace
gas observations into the chemistry transport model SILAM
(System for Integrated modeLling of Atmospheric coMposition) using the 3D-Var method. Assimil...
“Probabilistic calibration of a Greenland Ice Sheet model using spatially resolved synthetic observations: toward projections of ice mass loss with uncertainties” published in Geosci. Model Dev., 7, 1933–1943, 2014
Greenland Ice Sheet spatially resolved synthetic observations
2014/12/19
Due to an oversight in the production process, the article “Probabilistic calibration of a Greenland Ice Sheet model
using spatially resolved synthetic observations: toward projections of ice mass lo...
Intercomparison of temperature trends in IPCC CMIP5 simulations with observations, reanalyses and CMIP3 models
temperature trends IPCC CMIP5 simulations observations reanalysis CMIP3 models
2014/12/12
On the basis of the fifth Coupled Model Intercomparison Project (CMIP5) and the climate model simulations covering 1979 through 2005, the temperature trends and their uncertainties have been examined ...
The global middle-atmosphere aerosol model MAECHAM5-SAM2: comparison with satellite and in-situ observations
global middle-atmosphere aerosol model ECHAM5-SAM 2 comparison with satellite in-situ observations
2014/12/9
In this paper we investigate results from a three-dimensional middle-atmosphere aerosol-climate model which has been developed to study the evolution of stratospheric aerosols. Here we focus on the st...
Climate and Environmental Change in Arctic Canada: Observations from Upper and Lower Murray Lakes, Ellesmere Island, Nunavut
Arctic Climate Holocene Lakes
2014/10/22
This study was designed with the overriding goal of improving our understanding of the nature, causes, and impacts of past climatic conditions in the High Arctic and to evaluate the potential impacts ...
Earth to data: Making sense of environmental observations（图）
sense environmental observations Earth
2014/12/1
As with the proverbial canary in the coal mine, birds serve as an indicator of the health of our environment. Many common species have experienced significant population declines within the last 40 ye...
Adjustment of Gravity Observations towards a Microgal Precision
Calibration Gravimeter Gravity Network Adjustment Modeling
2013/3/11
Gravity observations adjustment is studied having in view to take full advantage of the modern technology of gravity measurement. We present here results of a test performed with the mathematical mode...
Maastrichtian Rudist Fauna from Tarbur Formation (Zagros Region, SW Iran): Preliminary Observations
Tarbur Formation Preliminary Observations
2010/12/20
The uppermost Cretaceous Tarbur Formation of the Zagros region (SW Iran) is mainly siliciclastic in composition, though it also incorporates some carbonate units including several rudist lithosomes.
Estimation of the Degree of Saturation of Shallow Soils from Satellite Observations to Model Soil Slips Occurred in Emilia Romagna Region of Northern Italy
Degree of Saturation Soil Slip Satellite Observations
2013/3/6
For the development of alert systems for soil slip occurrence, it is important to evaluate the degree of saturation of shallow soils (Sr) over wide areas. Taking into account the possibility to estima...
The use of products from ground-based GNSS observations in meteorological nowcasting
The use products from ground-based GNSS observations meteorological nowcasting
2010/9/10
Convective rainfall is often focalized in areas of moisture convergence. A close relationship between precipitation and fast variations of vertically-integrated water vapour (IWV) has been found in nu...
Mobile MAX-DOAS observations of tropospheric trace gases
Mobile MAX-DOAS observations tropospheric trace gases
2010/2/8
From Multi-Axis- (MAX-) DOAS observations, information on tropospheric trace gases close to the surface and up to the free troposphere can be obtained. Usually MAX-DOAS observations are performed at f...
Forecasting temperate alpine glacier survival from accumulation zone observations
Forecasting temperate alpine glacier survival accumulation zone observations
2010/2/3
Temperate alpine glacier survival is dependent on the consistent presence of an accumulation zone. Frequent low accumulation area ratio values, below 30%, indicate the lack of a consistent accumulatio...
On the potential of sub-mm passive MW observations from geostationary satellites to retrieve heavy precipitation over the Mediterranean Area
sub-mm passive MW geostationary satellites
2010/1/27
The general interest in the potential use of the mm and sub-mm frequencies up to 425 GHz resolution from geostationary orbit is increasing due to the fact that the frequent time sampling and the compa...
