Undercatch of tipping-bucket gauges in high rain rate events
Undercatch of tipping-bucket gauges high rain rate events
2010/9/10
We have investigated differences in rainfall accumulations for seven high rain rate events from three gauges: a Geonor T-200B vibrating-wire weighing gauge and two MetOne tipping-bucket gauges. The Ge...
Dual-polarization C-band weather radar algorithms for rain rate estimation and hydrometeor classification in an alpine region
Dual-polarization C-band weather rain rate
2010/2/3
Dual polarization is becoming the standard for new weather radar systems. In contrast to conventional weather radars, where the reflectivity is measured in one polarization plane only, a dual polariza...
The knowledge of the crustal strain rate tensor provides a description of geodynamic processes such as fault strain accumulation, which is an important parameter for seismic hazard assessment, as well...
Rate of Iceland Sea acidification from time series measurements
Rate Iceland Sea acidification time series measurements
2010/1/21
The Iceland Sea is one part of the Nordic Seas. Cold Arctic Water prevails there and the deep-water is an important source of North Atlantic Deep Water. We have evaluated time series observations of m...
Increased rate of acceleration on Pine Island Glacier strongly coupled to changes in gravitational driving stress
Increased rate acceleration Pine Island Glacier gravitational driving stress
2010/2/3
Pine Island Glacier, Antarctica, has been undergoing several related changes for at least two decades; these include acceleration, thinning and grounding line retreat. During the first major ground-ba...
Triggered creep rate on the Ismetpasa segment of the North Anatolian Fault
creep rate Ismetpasa segment North Anatolian Fault
2010/1/4
The Ismetpasa segment of the North Anatolian Fault is one of the rare places in the world where aseismic creep event has been observed. This segment was ruptured during both the 1944, Mw=7.2, Gerede a...
Anthropogenic and biophysical contributions to increasing atmospheric CO2 growth rate and airborne fraction
Anthropogenic and biophysical contributions atmospheric CO2 growth rate airborne fraction
2010/1/18
We quantify the relative roles of natural and anthropogenic influences on the growth rate of atmospheric CO2 and the CO2 airborne fraction, considering both interdecadal trends and interannual variabi...
Spatial variation in N2-fixation rate and diazotroph activity in the Tropical Atlantic
Spatial variation N2-fixation rate diazotroph activity Tropical Atlantic
2010/1/14
A variety of N2-fixers occur in oligotrophic waters and these diazotrophs make a substantial contribution to the nitrogen budget of the upper water column. A synthesis of previously published and new ...
Statistical and neural classifiers in estimating rain rate from weather radar measurements
Statistical and neural classifiers rain rate weather radar measurements
2010/1/26
Weather radars are used to measure the electromagnetic radiation backscattered by cloud raindrops. Clouds that backscatter more electromagnetic radiation consist of larger droplets of rain and therefo...
Precipitation rate spectra as dependent on dynamic forcing:application to probabilistic forecasting
Precipitation rate spectra dynamic forcing pplication probabilistic forecasting
2010/1/26
Occurrence frequencies, OF, of 12-h precipitation amounts, P, at stations in the former European USSR are displayed as dependent on dynamic forcing of vertical motions. The dynamic forcing is describe...
Rainfall rate retrieval in presence of path attenuation using C-band polarimetric weather radars
Rainfall rate path attenuation C-band polarimetric weather radars
2009/12/29
Weather radar systems are very suitable tools for the monitoring of extreme rainfall events providing measurements with high spatial and temporal resolution over a wide geographical area. Nevertheless...
The effect of temperature,salinity and growth rate on the stable hydrogen isotopic composition of long chain alkenones produced by Emiliania huxleyi and Gephyrocapsa oceanica

2010/1/13
Two haptophyte algae, Emiliania huxleyi and Gephyrocapsa oceanica, were cultured at different temperatures and salinities to investigate the impact of these factors on the hydrogen isotopic compositio...
