The variations of gravity field have been analyzed in this article, in order to find disturbances in the vicinity of recent great earthquakes epicenters including Chile (February 27, 2010), Tohoku-Oki...
The long-lasting activity of 3C 454.3. GASP-WEBT and satellite observations in 2008-2010
galaxies: active – galaxies: quasars: general – galaxies: quasars: individual: 3C 454.3 – galaxies: jets
2011/9/28
We present multiwavelength observations of 3C 454.3 from April 2008 to March 2010. The radio to optical data are mostly from the GASP-WEBT, UV and X-ray data from Swift, and gamma-ray data from the AG...
Experimental simulation of satellite observations of 100 kHz radio waves from relativistic electron beams above thunderclouds
satellite observations 100 kHz radio waves relativistic electron beams thunderclouds
2011/2/24
Relativistic electron beams above thunderclouds emit 100 kHz radio waves which illuminate the Earth's atmosphere and near-Earth space. This contribution aims to clarify the physical processes which ar...
A very high-resolution (1 km×1 km) global fossil fuel CO2 emission inventory derived using a point source database and satellite observations of nighttime lights
a point source database satellite observations nighttime lights
2011/1/20
Emissions of CO2 from fossil fuel combustion are a critical quantity that must be accurately given in established flux inversion frameworks. Work with emerging satellite-based inversions requires spat...
Estimating European volatile organic compound emissions using satellite observations of formaldehyde from the Ozone Monitoring Instrument
European volatile organic compound satellite observations the Ozone Monitoring Instrument
2010/12/20
Emission of non-methane Volatile Organic Compounds (VOCs) to the atmosphere stems from biogenic and human activities, and their estimation is difficult because of the many and not fully understood pro...
Nitrogen oxides and PAN in plumes from boreal fires during ARCTAS-B and their impact on ozone: an integrated analysis of aircraft and satellite observations
Nitrogen oxides and PAN boreal fires ARCTAS-B aircraft and satellite observations
2010/10/21
We determine enhancement ratios for NOx, PAN, and other NOy species from boreal biomass burning using aircraft data obtained during the ARCTAS-B campaign and examine the impact of these emissions on t...
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...
Satellite observations of long range transport of a large BrO plume in the Arctic
Satellite observations a large BrO plume the Arctic
2010/8/16
In this study, BrO measurements from the satellite instrument GOME-2 are used together with model calculations with the dispersion model FLEXPART to study an arctic BrO event in March 2007, which coul...
Optimal estimation retrieval of aerosol microphysical properties from SAGE~II satellite observations in the volcanically unperturbed lower stratosphere
Optimal estimation aerosol microphysical properties SAGE~II satellite observations lower stratosphere
2010/8/12
Stratospheric aerosol particles under non-volcanic conditions are typically smaller than 0.1 μm. Due to fundamental limitations of the scattering theory in the Rayleigh limit, these tiny particles are...
Global atmospheric budget of acetaldehyde: 3-D model analysis and constraints from in-situ and satellite observations
Global atmospheric budget acetaldehyde 3-D model analysis and constraints in-situ and satellite observations
2010/8/12
We construct a global atmospheric budget for acetaldehyde using a 3-D model of atmospheric chemistry (GEOS-Chem), and use an ensemble of observations to evaluate present understanding of its sources a...
Smoke injection heights from fires in North America: analysis of 5 years of satellite observations
