Simultaneously assimilating multivariate data sets two-source evapotranspiration model Bayesian approach spring maize in an arid region of northwestern China
2014/12/19
Based on direct measurements of half-hourly canopy evapotranspiration (ET; W m−2) using the eddy covariance (EC) system and daily soil evaporation (E; mm day−1) using microlysimeters over ...
Paleoceanography of the South China Sea and the western equatorial Pacific: Testing linkages between Indonesian Seaway closure and sea level change during the Middle to Late Miocene (～13--5 Ma)
Paleoceanography the equator the equator of the south China sea west Pacific sea level climate change

Longmen Shan is located the special joint between the Qinghai-Tibetan Plateau in the west and the Yangtze craton in the east. Consisting of a series of parallel imbricated thrust, it develops, from th...
Impacts of spatial data resolution on simulated discharge, a case study of Xitiaoxi catchment in South China
simulated discharge Xitiaoxi catchment South China
2010/2/3
In this paper we analyse the effects of different spatial input data resolution on water balance simulation using a simple distributed hydrological model: PCR-XAJ model. A data set consisting of land ...
Hydrologic comparison between a lowland catchment (Kielstau, Germany) and a mountainous catchment (XitaoXi, China) using KIDS model in PCRaster
Hydrologic comparison Kielstau Germany
2010/2/3
The KIDS model (Kielstau Discharge Simulation model) is a simple rainfall-runoff model developed originally for the Kielstau catchment. To extend its range of application we applied it to a completely...
