Semiarid grasslands and extreme precipitation events: Do experimental results scale to the landscape?
This dataset contains growing season precipitation data collected from an extensive rain gauge network with thirty catch cans distributed on the USDA-Central Plains Experimental Range (CPER) in Nunn, Colorado from 1982-2013. The CPER is a site in the USDA Long-term Agroecosystem Research Network. These data provide records of long-term observations, which can be applied to assess responses to naturally occurring deluges across the 62.7 km2 CPER in NE Colorado, a SGS ecosystem with significant spatial variation in precipitation received during the growing season, soils and grazing management, and where several small-scale deluge experiments have been conducted.

Mean annual precipitation is 321 mm, and most rainfall (70%) occurs as patchy, often intense convective storms during the warm months (Lauenroth & Sala, 1992; Lauenroth & Burke, 2008). While most rain events are small (83% are ≤ 10 mm), these account for only 41% of total growing season rainfall; therefore, infrequent large rain events are important in this ecosystem and can be identified from long-term precipitation records such as this dataset. Precipitation amounts from 30 manual rain gauges distributed across the site from May thru September are usually recorded within 24 hours of a rain event. Data were verified with cross-validation of records contained in the National Atmospheric Deposition Program (NADP, 1980-present). An additional processed dataset is included, for which the authors identified isolated summer (June-September) deluge events. They define a deluge as a statistically large event size that exceeds the 90th percentile based on the long-term precipitation record (Post & Knapp, 2021). For this analysis, they summed precipitation from rain events that co-occurred temporally (typically over 2-4 days) and considered these as single deluge events.Temporal Extent Start Date
