Global gray-sky dT (Version 2): inverse of the surface psychrometric constant parameter in the SSEBop evapotranspiration model

The surface psychrometric constant (spc) is a key model parameter in actual evapotranspiration (ET) modeling using the Operational Simplified Surface Energy Balance (SSEBop) model for establishing model boundary limits for the dry/bare and wet/vegetated surface conditions. The inverse of the constant (1/spc) represents the temperature difference (dT) between the bare/dry surface and the...

Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2025

We provide fractional cover estimates for exotic annual grass (EAG) species and one native perennial grass species on a weekly basis from mid-April to late June 2025. The cover estimates reflect actual conditions of the previous week and are released in an expedited manner, within 7-13 days of the latest satellite observation used for that weekly prediction. Each weekly release contains...

Fuels Data for the 2021 KNP Complex Fire in Sequoia and Kings Canyon National Parks, Collected in 2024

Post-fire vegetation structure and fuels data are essential for understanding the recovery process after major disturbances. To meet this need, 40 plots within and around the perimeter of the 2021 KNP Complex Fire were surveyed between July 12 and July 28, 2024. Data was collected on sites previously established by the U.S. Geological Survey Kings Canyon and Sequoia Field Station, as...

Rangeland Condition Monitoring Assessment and Projection (RCMAP) Fractional Component Time-Series Across Western North America from 1985-2024

The RCMAP (Rangeland Condition Monitoring Assessment and Projection) dataset quantifies the percent cover of rangeland components across western North America using Landsat imagery from 1985-2024. The RCMAP product suite consists of ten fractional components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, tree, and shrub...

Preliminary Land Cover Data Collected for Protocol and Process Development related to Annual NLCD

Data collected to facilitate research and development activities pertaining to Annual NLCD algorithm development used as a benchmark for algorithm improvement iterations. The primary goal of these preliminary data was to offer preliminary insight into algorithm performance and guidance for algorithm improvement through error analysis.

ECCOE 2024 Surface Reflectance Validation Dataset

Scientists and engineers from the U.S. Geological Survey (USGS) Earth Resources Observation and Science Center (EROS) Cal/Val Center of Excellence (ECCOE) collected in situ measurements using field spectrometers to support the validation of surface reflectance products derived from Earth observing remote sensing imagery. Data provided in this data release were collected during select...

ECCOE 2023 Surface Reflectance Validation Dataset

Scientists and engineers from the U.S. Geological Survey (USGS) Earth Resources Observation and Science Center (EROS) Cal/Val Center of Excellence (ECCOE) collected in situ measurements using field spectrometers to support the validation of surface reflectance products derived from Earth observing remote sensing imagery. Data provided in this data release were collected during select...

Fuels Data for the 2000 Jasper Fire in the Black Hills of South Dakota, Collected in 2023 and 2024

Post-fire vegetation structure and fuel data are needed understand how an area recovers over time. To address this need, data were collected within the perimeter of the 2000 Jasper Fire near Custer, SD, on 73 plots co-located with plots previously established by scientists to assess burn severity. Vegetation structure data were collected at these plots during two periods: July 11–17...

Landscape Water Requirement Satisfaction Index (L-WRSI) from 1982 to Present at Dekadal Time Scale

The Landscape Water Requirement Satisfaction Index (L-WRSI) is an extension of the well-established water requirement satisfaction index (WRSI), which is an indicator of crop performance based on the availability of water to the crop during a growing season, by including the entire landscape and not just crop growing regions. L-WRSI is created using components generated by the VegET...

2021 Potomac River Phase II Topobathymetric Lidar Validation - USGS Field Survey Data

U.S. Geological Survey (USGS) scientists conducted field data collection efforts between September 30th and October 9th, 2021 over a large stretch of the Potomac River in Maryland and West Virginia using high accuracy surveying technologies. The work was initiated as an effort to validate commercially acquired topobathymetric light detection and ranging (lidar) data that was collected...

LANDFIRE 2023 (240) Update

The LANDFIRE 2023 Update (LF 2023) product suite represents the final step in the ongoing goal to move towards annual updates and reduced latency. LANDFIRE'S goal has been to release an annual update every year that represents one year, specifically the previous year. Similar to the LF 2022 Update, in LF 2023, disturbances from the previous year are represented in current year products...

Rangeland Condition Monitoring Assessment and Projection (RCMAP) Independent Validation Data

Rangeland ecosystems provide critical wildlife habitat (e.g., greater sage grouse, pronghorn, black-footed ferret), forage for livestock, carbon sequestration, provision of water resources, and recreational opportunities. At the same time, rangelands are vulnerable to climate change, fire, and anthropogenic disturbances. The arid-semiarid climate in most rangelands fluctuates widely...
