PPDIST, global 0.1° daily and 3-hourly precipitation probability distribution climatologies for 1979–2018

We introduce the Precipitation Probability DISTribution (PPDIST) dataset, a collection of global high-resolution (0.1°) observation-based climatologies (1979–2018) of the occurrence and peak intensity of precipitation (P) at daily and 3-hourly …

Cognitive Biases about Climate Variability in Smallholder Farming Systems in Zambia

Given the varying manifestations of climate change over time and the influence of climate perceptions on adaptation, it is important to understand whether farmer perceptions match patterns of environmental change from observational data. We use a …

Global-scale evaluation of 22 precipitation datasets using gauge observations and hydrological modeling

This study represents the most comprehensive global-scale precipitation dataset evaluation to date. We evaluated 13 uncorrected precipitation datasets using precipitation observations from 76 086 gauges, and 9 gauge-corrected ones using hydrological modeling for 9053 catchments. Our results highlight large differences in estimation accuracy, and hence, the importance of precipitation dataset selection in both research and operational applications.

Forecasting the Hydroclimatic Signature of the 2015/16 El Niño Event on the Western United States

Dry conditions in 2013–16 in much of the western United States were responsible for severe drought and led to an exceptional fire season in the Pacific Northwest in 2015. Winter 2015/16 was forecasted to relieve drought in the southern portion of the …

The impact of deforestation on the hydrological cycle in Amazonia as observed from remote sensing

Given widespread Amazonian deforestation, numerous studies have focused on how the regional hydrological cycle - in terms of precipitation (P) recycling from evapotranspiration (ET) - is impacted by deforestation. Nevertheless, climate macroscale and …
