A watershed management program is usually based on the results of watershed modeling. Accurate modeling results are decided by the appropriate parameters and input data. Precipitation is the most important input for watershed modeling. Precipitation characteristics usually exhibit significant spatial variation, even within small watersheds. Therefore, properly describing the spatial variation o...

Accurate precipitation data is essential for any hydrometeorological study, particularly calibration and simulation of hydrological models. In this paper, we evaluate the two different reanalysis products (the ERA5 GLDAS), satellite-based (TRMM 3B42 CHIRPS) over La Sierra river basins in Southern Mexico, on regional daily time scales, from 2008 to 2010. We compare collocated gridded against in-...

[1] Studies of extreme precipitation have documented changes at the continental scale during the twentieth century, but few studies have quantified changes at small to regional spatial scales during the same time. We analyze historic data from over 600 precipitation stations in the San Francisco Bay Area (SFBA), California, to assess whether there have been statistically significant changes in ...

Temperature sensitivity of soil organic carbon (SOC) mineralization (i.e., Q10) determines how strong the feedback from global warming may be on the atmospheric CO2 concentration; thus, understanding the factors influencing the interannual variation in Q10 is important for accurately estimating local soil carbon cycle. In situ SOC mineralization rate was measured using an automated CO2 flux sys...

felled, or girdle-poisoned) and compared measured mass loss with decay class designations. Study Site The study was installed at the US Department of Energy’s Savannah River Site (Kilgo and Blake 2005), a National Environmental Research Park, located in Aiken, Barnwell, and Allendale counties in the South Carolina upper Coastal Plain (33°25 N, 81°50 W). The climate is warm temperate to subtropi...

There is considerable debate over the relative importance of dispersal and environmental disturbances (the Moran effect) as causes of spatial synchrony in fluctuations of animal populations. If environmental factors generally exhibit high levels of spatial autocorrelation, they may be playing a more important role in synchronizing animal populations than sometimes recognized. Here I examine thi...

Although it has been documented that daily precipitation extremes are increasing worldwide, faster increases may be expected for subdaily extremes. Here after a careful quality control procedure, we compared trends in hourly and daily precipitation extremes using a large network of stations across the United States (U.S.) within the 1950–2011 period. A greater number of significant increasing t...

We evaluated precipitation quantity and inorganic N deposition from wetfall at the Saddle site on Niwot Ridge, an alpine location in the Colorado Front Range of the Rocky Mountains. The chemical content of precipitation was collected with an Aerometrics wet-only deposition collector and precipitation amount was collected in a co-located Fergusson-type weighing gauge with a wind shield. Calculat...
