A grid network version of the two-layer Variable Infiltration Capacity (VIC-2L) macroscale hydrological model is described. The VIC-2L model is a hydrologically-based SVAT (Soil Vegetation Atmospheric Transfer) scheme designed to represent the land surface in numerical weather prediction and climate models. It is coupled to a linear routing scheme which is optimized with measured precipitation ...

Land surface albedo is a key parameter representing the outgoing solar flux fractions reflected by earth surface . It is widely used as an input parameter for numerical radiation budget models, the hydrological cycle and climate modeling studies. Urban’s high albedo changes the original land surface radiation balance, high thermal diffusivity insulates the ground, and thus it represents a dry, ...

In the past, water resources in Australia have been over-allocated and this has led to the implementation of water reforms. An integrated assessment project is underway in the Namoi Catchment, located in New South Wales, Australia, that aims to assess the social, economic and ecological impacts of reductions in water allocations under current and future environmental conditions. Surface and gro...

The factors determining the spatial and temporal distribution of West Nile virus (family Flaviviridae, genus Flavivirus, WNV) activity are not well understood. Here, we explore the effects of hydrological and meteorological conditions on WNV infection among Culex genus mosquitoes collected during 2001-2009 in Suffolk County, Long Island, NY. We show that WNV infection rates in assayed pools of ...

The understanding of land surface hydrology is critical for planning human activities involving freshwater 10 resources. We assess how atmospheric forcing data uncertainties affect land surface model (LSM) simulations by means of an extensive evaluation exercise using a number of state-of-the-art remote sensing and station-based datasets. For this purpose, we use the CO2-responsive ISBA-A-gs LS...

In the Peruvian Andes, water infiltration from tropical wetlands, called páramo, generates headwaters for downstream rivers. The hydrological processes of these wetlands are not well understood within the larger hydrological system, impeding efforts to mitigate the rapid environmental changes anticipated due to regional population growth and climate change. This study constructed and calibrated...

Recent studies have drawn attention to a significant weakening trend of the South Asian monsoon circulation and an associated decrease in regional rainfall during the last few decades. While surface temperatures over the region have steadily risen during this period, most of the CMIP (Coupled Model Intercomparison Project) global climate models have difficulties in capturing the observed decrea...
