Assessing methane emissions from global space-borne observations.
In the past two centuries, atmospheric methane has more than doubled and now constitutes 20% of the anthropogenic climate forcing by greenhouse gases. Yet its sources are not well quantified, introducing uncertainties in its global budget. We retrieved the global methane distribution by using spaceborne near-infrared absorption spectroscopy. In addition to the expected latitudinal gradient, we ...

Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract The causes of high tropospheric column ozone values over the Tropical Atlantic Ocean during September, October, and November (SON) are investigated by examining lightning during 1998–2001. The cause for high tropospheric column ozone in the hemisphere opp...
متن کاملSpace Weather Studies Using Low-frequency Interplanetary Scintillation Observations
Plasma disturbances originating on the Sun, such as coronal mass ejections (CMEs), are a major factor in determining ‘space weather’ in the near-Earth environment. Virtually the only current source of routine observations of these disturbances as they propagate through the interplanetary medium are interplanetary scintillation (IPS) data. We review current work on time-dependent tomographic rec...
متن کاملStellar Evolutionary Models: challenges from observations of stellar systems
We briefly review some constraints† for stellar models in various mass regimes and evolutionary stages as provided by observational data from spectroscopy to multi-wavelenghts photometry. The accuracy of present generation of stellar models can be significantly improved only through an extensive comparison between theory and observations.
متن کاملGlobal Ocean Surface Vector Wind Observations from Space
The global ocean surface vector wind is a key climate and operational observation, achievable from proven space-borne scatterometer systems. Science and operational requirements for sampling frequency, record length, spatial resolution, and global coverage are described in a climate context, using explicit examples in physical oceanography and air-sea interactions. A loosely coordinated assembl...
