Undercatch of tipping-bucket gauges in high rain rate events
Undercatch of tipping-bucket gauges high rain rate events
font style='font-size:12px;'>
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

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

font style='font-size:12px;'>
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
font style='font-size:12px;'>
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 ...
