Research Primer

Background

Mountain snowpack is the lifeblood of the western United States. In the Upper Colorado River Basin (UCRB), which includes the East River watershed near Gothic, Colorado, snow that accumulates each winter melts in spring and early summer to supply roughly 40 million people downstream. Yet for decades, hydrologists have struggled with a stubborn mismatch: even when snowpack measurements look healthy, the streamflow that follows is often lower than expected. Understanding why requires tracking water through the full mountain system — from the clouds that deliver snowfall, through the snowpack on the ground, into soils and streams, and back to the atmosphere through evaporation and plant uptake. This neighborhood of research focuses on the observations, models, and monitoring networks that make such tracking possible.

A few key concepts thread through the findings below. Snow water equivalent (SWE) is the depth of water you would get if you melted the snowpack in place; it is the single most important number for forecasting summer water supply. Sublimation is the direct conversion of snow to water vapor without melting, and it can quietly remove a large share of winter snowfall before it ever reaches a stream. Surface albedo describes how much sunlight a surface reflects — fresh snow reflects most of it (around 0.8–0.9), while bare or dust-covered ground absorbs much more, accelerating melt. Cloud radiative forcing measures how clouds change the energy reaching the surface relative to clear skies, which depends strongly on whether the ground beneath is snowy or bare.

Researchers also rely on aerosols (tiny airborne particles that seed cloud droplets and ice crystals), eddy covariance (a method for measuring water and energy exchange between the surface and atmosphere using high-frequency wind and humidity sensors), and lidar (laser-based remote sensing that maps snow depth and forest structure). Together, these tools let scientists describe the complex terrain of the Gunnison Basin — the mountain ridges, valleys, and forests that make precipitation, wind, and snow distribution so spatially variable, and so hard to predict from coarse climate models.

Foundational work

Early skill assessments of operational water-supply forecasts in the Colorado River Basin established a baseline understanding of what monitoring could and could not predict. Forecast accuracy improves steadily through the snow season as more snowpack data accumulate, but middle-of-the-road runoff years remain stubbornly hard to predict, and forecast skill correlates very strongly with seasonal precipitation rather than basin elevation (Harrison & Bales, 2015). These results pointed to a clear need: better, denser, more vertically integrated observations of precipitation and snow across mountain landscapes.

That need motivated community-driven monitoring efforts in the Colorado headwaters. The Roaring Fork soil-moisture and weather network, built between 2012 and 2020 along an elevational gradient from 1,800 to 3,680 meters, demonstrated how locally rooted observation networks could provide the long-term, multi-variable records that mountain hydrology research and adaptation planning require (Osenga et al., 2021). Together, these foundational efforts framed the central scientific question driving the field today: where exactly does mountain water go between snowfall and streamflow?

Key findings

The most ambitious answer to that question has come from a pair of overlapping field campaigns in the East River watershed. The Surface Atmosphere Integrated Field Laboratory (SAIL), deployed from September 2021 to June 2023, brought a Department of Energy atmospheric observatory into complex mountain terrain to measure precipitation, clouds, winds, aerosols, radiation, and snowpack interactions simultaneously (Feldman et al., 2023). Alongside SAIL, NOAA's SPLASH campaign installed five surface observing sites plus airborne and remote sensors to track how mountain precipitation becomes streamflow (de Boer et al., 2023). Continuous surface energy and meteorological observations from SPLASH now provide a benchmark dataset for the seasonally snow-covered high-elevation watershed (Cox et al., 2025).

These campaigns have begun to quantify the missing water. A dedicated sublimation experiment with more than 100 instruments on four flux towers showed that sublimation can remove 10%–90% of snowfall, with blowing snow playing a major role and surface albedo strongly modulating energy balance (Lundquist et al., 2024). Forest structure also matters: airborne lidar combined with deep learning at Grand Mesa, Colorado revealed that complex, vertically arranged canopies intercept more snow and produce shallower snowpack beneath them (Hojatimalekshah et al., 2023). Mapping snow itself has improved dramatically — a convolutional neural network applied to PlanetScope satellite imagery, augmented with vegetation indices and elevation data, produces meter-scale snow-cover maps in forested terrain (John et al., 2022), while integrating ground-penetrating radar with airborne lidar at Grand Mesa now yields spatially distributed snow density and SWE with median uncertainty around 13% (Meehan et al., 2024).

Clouds and aerosols complete the picture. Over a 21-month record at high elevation in the UCRB, longwave warming from clouds dominates in winter (raising net surface radiation by up to +34.7 W/m²), but clouds switch to a strong cooling effect once snow recedes — a pattern that depends critically on surface albedo and suggests cloud effects will intensify as snow cover declines (Rudisill et al., 2025). Regional climate modeling at 1-km resolution over three decades shows reasonably low cool-season precipitation bias against SNOTEL stations but larger warm-season errors (Rudisill et al., 2023), and the choice of cloud microphysics scheme can shift watershed precipitation by a few percent overall and up to 15% locally (Rudisill et al., 2024). Aerosol observations across SAIL-Net's six measurement nodes have begun quantifying how variable cloud-seeding particles are across the mountain landscape (Gibson et al., 2025).

Current frontier

With 22 of the 23 publications in this neighborhood appearing since 2020, the field is in a moment of rapid expansion. Recent work is moving from describing what happens at single points toward characterizing spatial variability across the watershed. Studies are now probing the fine details of mountain weather: why thermally driven up-valley winds in the East River often reverse unexpectedly by midmorning during the warm season (Adler et al., 2025), how snow microphysical processes like riming and aggregation evolve inside orographic clouds (Kotsche et al., 2025), and how mechanical properties of the snowpack itself vary in space (Tedesche et al., 2025). Long-term measurements of ice-nucleating particles across global atmospheric observatories, including UCRB sites, are beginning to constrain how biological and dust aerosols influence snowfall (Creamean et al., 2025).

Methodologically, the frontier is increasingly defined by data fusion — combining radar, lidar, satellite imagery, and machine learning to extract quantities that no single instrument can measure. Ensemble learning approaches are now being used to predict cloud-seeding aerosol concentrations from optical properties (Wang et al., 2025), and harmonized multi-site aerosol datasets are enabling cross-site comparisons that were previously impossible (Andrews et al., 2025).

Open questions

Despite remarkable progress, several first-order questions remain. How much of the chronic mismatch between snowpack and streamflow in the Upper Colorado is explained by sublimation versus evapotranspiration versus subsurface storage, and how will those proportions shift as winters warm? How will the cloud–albedo relationship evolve as snow cover declines, and could a self-reinforcing feedback further reduce mountain water yield? Can fine-scale observations from campaigns like SAIL and SPLASH be translated into operational forecasts that improve the persistent skill gap for mid-flow years (Harrison & Bales, 2015)? And how transferable are findings from the East River watershed to other headwater basins with different forest cover, dust exposure, and storm tracks? Answering these questions will require sustaining the dense, multi-disciplinary observation networks that the past five years have established, while extending them across longer time spans and broader geographies.
