A validation assessment of Annual National Land Cover Dataset (NLCD) CONUS Collection 1.0 annual land cover products (1985–2023) for the Conterminous United States (CONUS) was conducted with an independently collected reference dataset. Reference data land cover attributes were assigned by trained interpreters for each year of the time series (1984–2023) to a reference sample of 8,360...

This Annual NLCD Reference Data Product includes the collection of an independent dataset of 8,360 30-meter by 30-meter samples across the Conterminous United States (CONUS). The Annual NLCD Collection 1 sample design was developed as a two-phase collection by a team of image interpreters as follows: an initial base sample containing 5,000 sample plots chosen purely by simple random...

The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, SD has developed a cloud validation dataset from Collection 2 images throughout the history of Landsat. Two North American locations with high overlap between WRS-1 and WRS-2 were chosen. For each location, 20 images were selected at random from the Landsat archive, with at least one...

USGS Evapotranspiration estimates provide useful information for a range of land use applications, from calculating a basin’s water budget to assessment of water consumption for crop yield and drought monitoring. This USGS data release is a result of using the OpenET Google Earth Engine (GEE) implementation of the USGS EROS Operational Simplified Surface Energy Balance (SSEBop)...

Rangelands have immense inherent spatial and temporal variability, yet assessments of land condition and trends are often assessed relative to the condition of a limited number of representative points or in some cases reference data is lacking. Ecological Potential (EP) data are spatially comprehensive and quantitative baseline for comparison of current rangeland vegetation conditions...

Landsat 8 and Landsat 9 Earth imaging acquisitions are guided by their respective Long Term Acquisition Plan (LTAP), that has been established for each satellite observatory. The LTAP is structured around the Worldwide Reference System-2 (WRS-2) grid, which partitions Landsat swath imaging of the Earth into ~185 × 180 km scenes using a path/row notation. These WRS-2 scenes represent the

U.S. Geological Survey (USGS) scientists conducted field data collection efforts between April 27 and May 2, 2023, at four sites (Fort Zachary Taylor Historic State Park, Bahia Honda State Park, Curry Hammond State Park, and Long Key State Park), in the Florida Keys using high accuracy surveying technologies. Wadded Global Navigation Satellite System (GNSS) points and single beam sonar...

This dataset represents a validation record for Landsat 8/9 Operational Land Imager (OLI) Aquatic Reflectance (AR) products. The dataset consists of combined AERONET-OC (n=418) and GLORIA (n=1,638) hyperspectral remote sensing reflectance (Rrs) measurements in the visible to near infrared spectral bands coincident with same-day OLI acquisitions. The dataset is intended to evaluate the...

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...

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...

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...

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...
