VISSS Raw data from SAIL at Gothic from November 2022 to June 2023
A Video in situ Snowfall Sensor (VISSS) records shadow images of precipitating hydrometeors from two perspective at a 90 degree angle with a frequency of 140 Hz. From this, hydrometeor properties such as particle size, shape, complexity, degree of riming, and fall velocity can be derived. The VISSS
Green Light for Adaptive Policies on the Colorado River
The Colorado River is a critical source of water supply for 40 million people in nine states spanning two nations in western North America. Overallocated in the 20th century, its problems have been compounded by climate change in the 21st century. We review the basin’s hydrologic and water managemen
Yampa River-Colorado River Drainage Divide Origin Determined from Topographic Map Evidence, Southern Routt County, Colorado, USA
Detailed topographic map evidence and a new Cenozoic geologic and glacial history paradigm are used to determine the previously unexplained Yampa River-Colorado River drainage divide origin. The Yampa River now flows in a north direction away from the Colorado River (between the Park Range to the ea
Using Remote Sensing Data Fusion Modeling to Track Seasonal Snow Cover in a Mountain Watershed
Seasonal snowfall is the largest component of the water budget in many mountain headwater regions around the world. In addition to sustaining biological water needs in drier, lower elevation areas throughout the year, mountain snowpack also provides essential water inputs to the Critical Zone (CZ) -
Energy Fluxes of Terrestrial and Aquatic Invertebrates in the East River
Climate change is increasing temperatures globally including aquatic habitats like rivers, directly affecting the biology of many invertebrate species. In freshwater ecosystems, snow melt drives rivers in the Rocky Mountains of Colorado. Increasing river temperatures can result in increasing metabol
Comparing pollen distribution on pollinators to floral community composition in the East River Valley
While plant-pollinator networks are salient markers of biodiversity, their mechanisms remain poorly understood. One theory describing pollination interactions is the Neutral Theory of Biodiversity, which asserts that plant-pollinator interactions are neutral, random processes based on species’ abund
Improving predictions of stream CO2 concentrations and fluxes using a stream network model: A case study in the East River watershed, CO, USA
Abstract Inland waters are an important component of the global carbon budget. However, our ability to predict carbon fluxes from stream systems remains uncertain, as p CO 2 varies within streams at scales of 1–100 m. This makes direct monitoring of large‐scale CO 2 fluxes impractical. We incorporat
Modeling the Impact of Riparian Hollows on River Corridor Nitrogen Exports
Recent studies in snowmelt-dominated catchments have documented changes in nitrogen (N) retention over time, such as declines in watershed exports of N, though there is a limited understanding of the controlling processes driving these trends. Working in the mountainous headwater East River Colorado
