Mapping 1 April SWE in the western US using standardized anomalies and quantiles from SWE reanalysis and in situ stations

Besso, H., Mower, R., Pflug, J. M., Lundquist, J. D.. (2026). Mapping 1 April SWE in the western US using standardized anomalies and quantiles from SWE reanalysis and in situ stations. Water Resources Research, doi:https://doi.org/10.1029/2025wr040902

Real-time estimates of peak snow water equivalent (SWE) are critical to spring runoff forecasts in snow-dominated basins, but large uncertainties remain due to the high spatial and temporal variability of interannual peak SWE. Here we intro...

The growing threat of spatially synchronized dry-hot events to global ecosystem productivity

Hassan, W. U., Nayak, M. A., Saharwardi, M. S., Gandham, H., Dasari, H. P., et al. (2026). The growing threat of spatially synchronized dry-hot events to global ecosystem productivity. Communications Earth and Environment, doi:https://doi.org/10.1038/s43247-026-03203-w

Compound hazards, like simultaneous occurrence of unusually dry and hot (DH) weather, cause cascading socio-economic damages that surpass univariate hazards. In the context of agricultural production, DH events triggered by pressure and moi...

Integrating climate data and river modeling to reveal Chinook salmon habitat conditions in subarctic river basins

Shaftel, R., Feddern, M. L., McAfee, S. A., Schoen, E. R., Cunningham, C., et al. (2026). Integrating climate data and river modeling to reveal Chinook salmon habitat conditions in subarctic river basins. Ecosphere, doi:https://doi.org/10.1002/ecs2.70399

Climatic extremes can impact the productivity of aquatic species, affecting ecosystems and fishery-dependent communities. Advances in climate products, such as gridded datasets and downscaled projections, may be useful for quantifying fresh...
