The role of soil states in medium-range weather predictability
soil states medium-range weather predictability
2009/11/12
Current day operational ensemble weather prediction systems generally rely upon perturbed atmospheric initial states, thereby neglecting the eventual effect on the atmospheric evolution that uncertain...
The UV-A and visible solar irradiance spectrum: inter-comparison of absolutely calibrated, spectrally medium resolution solar irradiance spectra from balloon- and satellite-borne measurements
UV-A and visible solar irradiance spectrum spectrally medium resolution solar irradiance spectra
2009/2/12
Within the framework of the ENVISAT/-SCIAMACHY satellite validation, solar irradiance spectra are absolutely measured at moderate resolution in the UV/visible spectral range (in the UV from 316.7-418...
Isolated lower mesospheric echoes seen by medium frequency radar at 70° N, 19° E
Isolated lower mesospheric echoes medium frequency radar
2009/1/20
We have noted sporadic instances of strong isolated reflections of medium frequency (MF) radar waves from the mesosphere from as low as 50 km altitude and have devised a set of criteria for isolating ...
Medium-range mid-tropospheric transport of ozone and precursors over Africa: two numerical case studies in dry and wet seasons
mid-tropospheric transport ozone Africa dry wet seasons
2008/12/23
A meso-scale model was used to understand and describe the dynamical processes driving high ozone concentrations observed during both dry and monsoon season in monthly climatologies profiles over Lago...
Short- and medium-term atmospheric constituent effects of very large solar proton events
atmospheric constituent solar proton
2008/10/29
Solar eruptions sometimes produce protons, which impact the Earth's atmosphere. These solar proton events (SPEs) generally last a few days and produce high energy particles that precipitate into the E...
