Abstract Wildfire occurrence and severity is predicted to increase in the upcoming decades with severe negative impacts on human societies. The of upwind wildfire activity glacier melt, a critical source freshwater for downstream environments, were investigated through analysis field remote sensing observations modeling experiments 2015–2020 melt seasons at well‐instrumented Athabasca Glacier Canadian Rockies. Upwind influenced surface both decrease albedo from deposition soot impact smoke...
Abstract. Uncertainty in estimating precipitation mountain headwaters can be transmitted to estimates of river discharge far downstream. Quantifying and reducing this uncertainty is needed better constrain the hydrological predictions rivers with headwaters. Spatial estimation fields accomplished through interpolation snowfall rainfall observations. These are often sparse mountains, so gauge density greatly affects uncertainty. Elevational lapse rates also influence as they vary widely...
Abstract Reliable precipitation forcing is essential for calculating the water balance and other hydrological variables. However, satellite often only available to run models in data‐scarce regions compromising calculations. The Integrated Multi‐satellitE Retrievals GPM (IMERG) product estimates from passive microwave infrared satellites, which are intercalibrated based on Global Precipitation Measurement (GPM)'s Dual‐frequency Radar (DPR) Microwave Image (GMI) instruments.

Abstract The Canadian Rockies are a triple-continental divide, whose high mountains drained by major snow-fed and rain-fed rivers flowing to the Pacific, Atlantic, Arctic Oceans. objective of April–June 2019 Storms Precipitation Across continental Divide Experiment (SPADE) was determine atmospheric processes producing precipitation on eastern western sides during springtime, period when upslope events variable phase dominate slopes. To do so, three observing sites across divide were...
Abstract. The continental divide along the spine of Canadian Rockies in southwestern Canada is a critical headwater region for hydrological drainages to Pacific, Arctic, and Atlantic oceans. Major flooding events are typically attributed heavy precipitation on its eastern side due upslope (easterly) flows. Precipitation can also occur western when moisture originating from Pacific Ocean encounters west-facing slopes Rockies. Often, storms propagating across result significant both sides....
This paper provides an early career researchers (ECRs) perspective on major challenges and opportunities that arise in the study understanding of, provision of regional information for Climate, Weather Hydrological (CWH) extreme events. emerged from discussions three-day Young Earth System Scientists - Hydrologic Society (YESS-YHS) workshop, which was conjointly held with Global Energy Water Exchanges (GEWEX) Open Science Conference. In this we discuss three possible ways forward field: a...
Wildfires and heatwaves have recently affected the hydrological system in unprecedented ways due to climate change. In cold regions, these extremes cause rapid reductions snow ice albedo soot deposition unseasonal melt. Snow dynamics control net shortwave radiation available energy for melt runoff generation. Many algorithms models cannot accurately simulate because they were developed or parameterised based on historical observations. Remotely sensed data assimilation (DA) can potentially...

Reliable precipitation forcing is essential for calculating the water balance, seasonal snowpack, glacier mass streamflow, and other hydrological variables. However, satellite often only available to run models in data-scarce regions, compromising calculations when unreliable. The IMERG product estimates quasi-globally from a combination of passive microwave infrared satellites, which are intercalibrated based on GPM’s DPR GMI instruments. Current GPM-DPR radar algorithms have satisfactorily...

Hydrological modelling is largely applied to forecast the effects of extreme rainfall on runoff dynamics. Little research has been done coupling numerical weather prediction (NWP) and hydrological in southern Brazil given limited hydrometeorological NWP data available for region. In this study, we evaluate a method semi-distributed model humid subtropical catchment (286 km²) Brazil, state Santa Catarina, municipality Vidal Ramos. The HEC-HMS was manually calibrated validated using 2013. Four...
