Long Term Agroecosystem Research Overview
- Agroecosystem productivity is sustainably enhanced by the development and application of new technologies
- Mitigation and adaptation of agroecosystems to climate change is improved by more accurate predictions of resource responses to system drivers
- Stronger linkages to other long-term research networks improves conservation and environmental quality in agricultural landscapes
- The socio-economic viability of, and opportunities for, rural communities are enhanced through educational outreach by LTAR scientists and collaborators
LTAR Research Sites
Data from the following LTAR sites are presented. They are related to topics such as agricultural sustainability, climate change, ecosystem services, and natural resource conservation at the watershed or landscape scale.
LTAR Great Basin Wyoming Big Sage Brush Meteorological Station, Reynolds Creek Experimental Watershed
Near-real time weather records collected at the Wyoming Big sagebrush meteorological site of the Great Basin LTAR. The station data is composited from a meteorological station and a nearby Eddy Covariance station.
The USDA-ARS Southwest Watershed Research Center (SWRC) operates the Walnut Gulch Experimental Watershed (WGEW) in southeastern Arizona as an outdoor laboratory for studying semiarid rangeland hydrologic, ecosystem, climate, and erosion processes.

Long-Term Agricultural Research (LTAR) network - Meteorological Station - Rock Springs - Upper Chesapeake Bay
The USDA-ARS Pasture Systems and Watershed Management Research Unit established a meteorological station in 2015 as part of the Upper Chesapeake Bay (UCB) site in the Long-Term Agroecosystem Research (LTAR) network (est. 2012).
US Department of Agriculture Soil Climate Analysis Network (SCAN) site 2195 data, CMRB LTAR-MO, Columbia, Missouri
This dataset contains air temperature, relative humidity, precipitation, solar radiation, wind speed, soil temperature, and soil moisture data from Soil Climate Analysis Network (SCAN) site 2195 in Boone County, Missouri.
The SWRC operates the Walnut Gulch Experimental Watershed (WGEW) in southeastern Arizona as an outdoor laboratory for studying semiarid rangeland hydrologic, ecosystem, climate, and erosion processes.
The Walnut Gulch Experimental Watershed (WGEW) sediment collection program, established in 1953, provides event-based data for semiarid rangeland erosion, sediment transport, and yield research.
