The Water, Energy, and Biogeochemical Model now available

Feb. 13, 2017

WEBMOD model "buckets." Image: USGS NRP The USGS NRP recently released the Water Energy and Biogeochemical Model (WEBMOD) that simulates water and solute fluxes through watersheds. More specifically, the semi-distributed water-scale water-balance model simulates hydrologic and geochemical storages and fluxes on a daily time step. The model framework utilizes the...

The recent “atmospheric river” weather pattern that pummeled California with storms from late December to late-January may have recouped 37 percent of the state’s five-year snow-water...

CO Wildfire

Aridity and wildfires driving hazier Western US skies

Jan. 13, 2017

2016 wildfire in Beaver Creek, CO As the Western US is projected to get dryer, research suggests a correlated increase in wildfire-derived aerosol loading. Yet the feedback between these factors and climate warming pose uncertainties in predicting future climate. A new study detailing the the relationships between aridity, aerosol loading,...
