Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Sample details and compositional data collected during episodes 1–39 (2024-2025) of the 2024-ongoing episodic Halema‘uma‘u eruption of Kīlauea, Island of Hawaiʻi Sample details and compositional data collected during episodes 1–39 (2024-2025) of the 2024-ongoing episodic Halema‘uma‘u eruption of Kīlauea, Island of Hawaiʻi
Samples for episodes 1–39 (2024-2025) of the 2024-ongoing episodic Halema‘uma‘u Kīlauea eruption were collected by the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) field teams from within publicly closed areas of Hawai‘i Volcanoes National Park in cooperation with the National Park Service. This data release presents sample metadata, whole rock ED-XRF, whole rock WD-XRF...
Monthly Raster Imagery, Historic Wetland Boundaries, and Management Period Mean Images for the Cebolla Spring Wetland in New Mexico Monthly Raster Imagery, Historic Wetland Boundaries, and Management Period Mean Images for the Cebolla Spring Wetland in New Mexico
Alluvial wetland ecosystems, such as the Cebolla Creek spring-fed wetland in east-central New Mexico, serve as biodiversity hotspots and directly affect processes such as water cycling and carbon sequestration. However, these systems are highly vulnerable to degradation because of drought, groundwater pumping, and channel incision. The "Zeedyk" approach for restoration employs methods...
Ultraviolet remote sensing data from a spectrometer fenceline array (DFence) installed at Kīlauea for measuring volcanic gas emissions Ultraviolet remote sensing data from a spectrometer fenceline array (DFence) installed at Kīlauea for measuring volcanic gas emissions
In 2012, the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) installed an array of zenith-pointing ultraviolet spectrometers to track gas emissions from summit of Kīlauea (Businger et al., 2015; Elias et al., 2018). The instruments are arranged in an arc perpendicular to the dominant trade-wind direction approximately 2 kilometers (km) southwest of the actively degassing...
Observed and predicted thermal exposure data, and associated land cover characteristics, of commuting locations in Denver Colorado Observed and predicted thermal exposure data, and associated land cover characteristics, of commuting locations in Denver Colorado
Examining urban thermal environments has become a critical area of research spanning epidemiology, urban planning, and ecology. While traditional metrics like air temperature (Tair) and satellite-derived surface temperature (SD-LST) dominate urban heat studies, these measures often fail to reflect how people actually experience thermal exposure intensity. More human-oriented metrics...
Model archive summary for suspended-sediment concentration at station 11516530, Klamath River below Iron Gate Dam, California, October 2023 to December 2024 Model archive summary for suspended-sediment concentration at station 11516530, Klamath River below Iron Gate Dam, California, October 2023 to December 2024
This model archive summary (MAS) and associated model calibration data describes a surrogate model used to compute suspended-sediment concentrations (SSC) at USGS streamgage 11516530 from October 2023 to December 2024. The period of analysis computes SSC during the drawdown and removals of three dams upstream of the streamgage and represents novel suspended-sediment transport conditions...
Exotic Annual Grass (EAG) Phenology estimates for Western U.S. Rangelands based on 30-m HLS for 2017 - 2025 Exotic Annual Grass (EAG) Phenology estimates for Western U.S. Rangelands based on 30-m HLS for 2017 - 2025
Monitoring plant life stages (i.e., phenology) is pertinent to land management as phenological dynamics reflect the vegetation response to changes in weather and disturbance and to changes in vegetation composition. Exotic Annual Grass (EAG) invasion has threatened habitats and economies across the western U.S. The phenology of EAG species, such as cheatgrass, differs from native...
