Sevilleta LTER Metstation number 49, precipition, daily raw and gap filled from 1992 - 2015
This file contains daily meteorological data collected from a network of 10 permanent weather stations on the Sevilleta National Wildlife Refuge. Multiple csv files were downloaded from the Sevilleta LTER data-portal (http://tierra.unm.edu/search/climate/search.php) and joined together in excel. Any missing data cells were gap-filled from the nearest meteorological station using Met_gap_fill.r. These data were sub-set for station 49, the station closest to our study site.
Meta-analytical data on soil organic, particulate organic, and mineral-associated organic carbon under nitrogen fertilization, elevated atmospheric carbon dioxide, atmospheric warming, increased precipitation, drought, and their combined effects
Data were harvested from journal articles found on the Web of Science Core Collection and the ProQuest Agricultural and Environmental Database that studied soil organic matter fraction carbon responses to global changes (nitrogen fertilization, elevated atmospheric carbon dioxide, atmospheric warming, increased and decreased precipitation, and combined effects). Soil organic carbon fractions were designated as particulate organic carbon or mineral-associated organic carbon based on size and density cutoffs. Relevant metadata, including article information (authors, publication year), environmental information (soil type, climate, and land use), and experiment information (rates, methods) were also added to the dataset.
Bulk precipitation collected during summer months on a per rain event basis at Toolik Field Station, North Slope of Alaska, Arctic LTER 1988 to 2007.
Bulk precipitation was collected during summer months (June, July and August) on a per rain event basis at the University of Alaska Fairbanks Toolik Field Station, North Slope of Alaska (68 degrees 37' 42"N, 149 degrees 35' 46"W). Analysis of pH, NH4-N and phosphorus were performed at the field station. NO3-N were frozen and analyzed in Woods Hole, MA
Bonanza Creek Experimental Forest Precipitation (Water Buckets/Rain Gauges) at BCEF LTER sites: Weekly
Three (in clearings) or four (under canopies) Weather Bureau standard rain gauges have been placed on stands at a height of approximately 1 m at each site with meteorological measurements. Rainfall is measured each week during the summer with a dip stick. Measurements are entered into the computer and averaged by site and date. Prior to 1991 measurements were in inches. These data have been converted to mm.

Sulfate isotopes in precipitation and streamwater, Hubbard Brook Experimental Forest, 1966 - 1994
Sulfur deposition in the northeastern U.S. has been decreasing since the 1970s and there has been a concomitant decrease in the SO4 lost from drainage waters from forest catchments of this region. It has been established previously that the SO4 lost from drainage waters exceeds SO4 inputs in bulk precipitation, but the cause for this imbalance has not been resolved. The use of stable S isotopes and the availability of archived bulk precipitation and stream water samples at the Hubbard Brook Experimental Forest (HBEF) in New Hampshire provided a unique opportunity to evaluate potential sources and sinks of S by analyzing the long-term patterns (1966–1994) of the d34S values of SO4. In bulk precipitation adjacent to the Ecosystem Laboratory and near Watershed 6 the d34S values were greater (mean: 4.5 and 4.2l, respectively) and showed more variation (variance: 0.49 and 0.30) than stream samples from Watersheds 5 (W5) and 6 (W6) (mean: 3.2 and 3.7; variance: 0.09 and 0.08, respectively). These results are consistent with other studies in forest catchments that have combined results for mass balances with stable S isotopes. These results indicate that for those sites, including the HBEF, where atmospheric inputs are 10 kg S ha-1 yr-1, most of the deposited SO4 cycles through the biomass before it is released to stream water. Results from W5, which had a whole-tree harvest in 1983–1984 showed that adsorption/desorption processes play an important role in regulating net SO4 retention for this watershed-ecosystem. Although the isotopic results suggest the importance of S mineralization, conclusive evidence that there is net mineralization has not yet been shown. However, S mass balances and the isotopic result are consistent with the mineralization of organic S being a major contributor to the SO4 in stream waters at the HBEF. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental F
Plant diverity and richness metrics across inter-annual precipitation variability treatments at a grassland site in the Jornada Basin, 2009-2014
This ongoing dataset contains metrics of plant diversity, evenness, and richness from a study at the Jornada Experimental Range (JER) in southern New Mexico. The study was designed to assess the effect of interannual variability in precipitation on average aboveground net primary productivity (ANPP) in Chihuahuan Desert grasslands. The study began in 2009, has five precipitation treatments (see Methods) and contains 50 plots (10 per treatment). This data package contains 6-year (2009 to 2014) means of metrics per plot. Annual and more recent data are available and will be released pending an upcoming publication.
Prairie du Sac - Sauk City, Wisconsin, monthly precipitation data
This is a compilation of total monthly precipitation data in total inches for two NOAA weather stations. The Prairie du Sac station data located at the Prairie du Sac dam on the Wisconsin River (43.31 , -89.7283) started with full monthly records being recorded in 1912 with complete monthly records through 2007. In mid-2007 a nearby station was established in Sauk City at the wastewater treatment plant (43.262 , -89.7349) with continuous data from 2008 through the present. The two stations are relatively close (about 3.25 miles apart), and both are slightly more than 4 miles to the west of the centroid of Fish Lake (Dane Co.) a core study lake in the North Temperate Lakes Long-Term Ecological Research Project conducted by the Center for Limnology at the University of Wisconsin-Madison. The compiled monthly records are based on daily NOAA precipitation records available electronically to the public. As a general practice, daily precipitation over weekends and holidays was not regularly recorded at the stations such that cumulative totals were recorded the following workweek day. As such, while the records for each single day were not always accurately recorded, the monthly totals were generally accurate. However, starting in 1996 at the Prairie du Sac station, because the cumulative weekend/holiday precipitation didn’t allow known daily totals, those cumulate weekend/holiday records were not submitted to NOAA so they were recorded as missing data in NOAA’s electronic dataset. To rectify the many months of missing data, pdf’s of the original hand-written monthly submissions were retrieved from NOAA’s archives such that the monthly precipitation totals could be calculated. In the process a few transcription errors in the electronic records of other months were also corrected in this dataset as well as determining a few other monthly records that were missing. Thus, this dataset of monthly precipitation at the two nearby weather stations is complete and hopefully accura
Precipitation disdrometer at C1 from October 2013 to May 2016
An OTT Parsivel Disdrometer is used to generate detailed precipitation information on the fall speeds and sizes of hydrometeors at the Niwot Ridge C1 site. This disdrometer data aids in the quantification of rain and snowfall microstructure allowing users of the data to investigate the influence that hydrometeor characteristics have on precipitation accumulation rates, streamflow/runoff, precipitation gauge errors, and radar reflectivity-rain/snow rate relationships (these are current uses of the data but there are many more possibilities). Parameters, such as intensity of precipitation, radar reflectivity, and visibility, are derived from the particle size and speed quantities and are complimentary to the other precipitation instrumentation at C1. The type of precipitation is derived from empirical relationships of fall speeds and volume-equivalent diameters and is useful for determining transitions between rain, graupel, snow, etc. The disdrometer at C1 fits into the larger goal of improving our understanding of orographic precipitation and the hydrometeorological dynamics at play on the eastern slopes of the Colorado Front Range.
Precipitation Chemistry Data For the Sevilleta National Wildlife Refuge, New Mexico (1989-present)
This data set includes precipitation chemisty from 20 funnel collectors on the Sevilleta National Wildlife Refuge (NWR). Variables measured include volume, NO3-N, NH4-N, SO4, Cl, Na, K, Ca, Mg, and PO4. The sample interval depends on the frequency of significant precipitations events. Field collection of precipitation chemistry samples occurred as soon after a significant precipitation event as possible (usually within a week after the event). In some cases collection of precipitation chemistry samples occurred more often than meteorlogical station samples (summer, fall), and sometimes less often (winter, spring). Precipitation chemistry samples were collected only when there was enough sample to allow for complete chemical analysis, (usually greater than 100mls). After 1995 all samples continued to be collected for volume but only an a partial set of the samples continued to be analyzed for inorganic nutrients.
Hobo Datalogger-Derived Precipitation Data from the Sevilleta National Wildlife Refuge, New Mexico (2008-present)
Precipitation is recognized as the most spatially variable abiotic variable in arid ecosystems such as the Sevilleta National Wildlife Refuge (NWR). Water is also usually the limiting factor in such environments so the accurate measurement of precipitation in both space and time is vital to understanding ecosystem dynamics. In 2008, the acquisition of a number of tipping-bucket rain gauges with Hobo dataloggers permitted the deployment of gauges into an increased number of locations on the Sevilleta NWR. Most dataloggers were installed in the greater Five Points area and primarily placed around the site of the 2003 burn study. A few additional dataloggers were installed throughout the entire Sevilleta NWR to expand overall coverage.
Linking Precipitation and C3 - C4 Plant Production to Resource Dynamics in Higher Trophic Level Consumers: Lizard Data (2005-2006)
In many ecosystems, seasonal shifts in temperature and precipitation induce pulses of primary productivity that vary in phenology, abundance and nutritional quality. Â Variation in these resource pulses could strongly influence community composition and ecosystem function, because these pervasive bottom-up forces play a primary role in determining the biomass, life cycles and interactions of organisms across trophic levels. Â The focus of this research is to understand how consumers across trophic levels alter resource use and assimilation over seasonal and inter-annual timescales in response to climatically driven changes in pulses of primary productivity. We measured the carbon isotope ratios (d13C) of plant, arthropod, and lizard tissues in the northern Chihuahuan Desert to quantify the relative importance of primary production from plants using C3 and C4 photosynthesis for consumers. Â Summer monsoonal rains on the Sevilleta LTER in New Mexico support a pulse of C4 plant production that have tissue d13C values distinct from C3 plants. Â During a year when precipitation patterns were relatively normal, d13C measurements showed that consumers used and assimilated significantly more C4 derived carbon over the course of a summer; tracking the seasonal increase in abundance of C4 plants. Â In the following spring, after a failure in winter precipitation and the associated failure of spring C3 plant growth, consumers showed elevated assimilation of C4 derived carbon relative to a normal rainfall regime. These findings provide insight into how climate, pulsed resources and temporal trophic dynamics may interact to shape semi-arid grasslands such as the Chihuahuan Desert in the present and future.

Drought Impact on Desert Ecosystems, Drought Network precipitation manipulation experiment in desert grasslands
Climate change amplifies the global water cycle, making droughts more frequent and more severe. The hot deserts of the U.S. rely on the stability and frequency of water availability in order to sustain biological communities, making these ecosystems incredibly vulnerable to anticipated alterations in the water cycle. This project seeks to understand which biotic and abiotic variables are principle in determining desert ecosystem sensitivity to drought? To answer these questions, we have installed a drought manipulation that will simulate an extreme drought event by reducing annual precipitation by 66% in seven desert sites. Plant abundance data are collected annually to track changes in the plant community. Data collection began in Spring 2018. Treatments at three Sevilleta sites began in Fall 2018 after data collection in October 2018. Treatments started at four sites in Arizona and California in March and April of 2019 and spring pretreatment data collection. The treatments will last for four years.
