VIIRS/NPP Surface Reflectance Daily L3 Global 0.05 Deg CMG V001
The Visible Infrared Imaging Radiometer Suite (VIIRS) (https://lpdaac.usgs.gov/dataset_discovery/viirs) daily surface reflectance Climate Modeling Grid (VNP09CMG) Version 1 product provides an estimate of land surface reflectance from the Suomi National Polar-Orbiting Partnership (Suomi NPP) VIIRS sensor. Data are provided for three imagery bands (I1-I3) and nine moderate resolution bands (M1-M5, M7, M8, M10, M11) at 0.05 degree (~5,600 meter) resolution. The data are corrected for atmospheric conditions such as the effects of molecular gases, including ozone and water vapor, and for the effects of atmospheric aerosols.

There are 16 moderate-resolutionbands (750m at nadir), 5 image-resolution bands (375m), and one day-night band (DNB).
VIIRS/NPP Surface Reflectance 8-Day L3 Global 1km SIN Grid V001
The 8-day Visible Infrared Imaging Radiometer Suite (VIIRS) surface reflectance (VNP09A1) Version 1 composite product provides an estimate of land surface reflectance from the Suomi National Polar-Orbiting Partnership (Suomi NPP) VIIRS sensor for nine moderate resolution bands (M1 - M5, M7, M8, M10, M11) at nominal 1 kilometer resolution (~926 meter). The 1 kilometer dataset is derived through resampling the native 750 meter VIIRS resolution in the Level 2 input product. The data are corrected for atmospheric conditions such as the effects of molecular gases, including ozone and water vapor, and for the effects of atmospheric aerosols. Each pixel represents the best possible Level 2G observation during an 8-day period that is selected on the basis of high observation coverage, low sensor angle, the absence of clouds or cloud shadow, and aerosol loading. Included in the product along with the nine reflectance bands are day of year, reflectance band quality, control, reflectance state quality assurance, relative azimuth angle, sensor zenith angle, and solar zenith angle layers.

Airborne Hyperspectral Reflectance Wood River Nebraska Multi-Day 1 m
The Airborne Hyperspectral Reflectance image mosaic is of the long-term prairie restoration and biodiversity study site led by the Nature Conservancy near Wood River, Nebraska (AEHYPWRNE1M). The approximately 1-meter (m) spatial resolution image was resampled in the 397 to 1004 nanometer (nm) spectral range. This image can be used to detect grassland biodiversity over time to help develop a regional biodiversity monitoring program.Airborne data for the long-term prairie restoration and biodiversity Wood River site were collected on four separate occasions: August 23, 2017; June 27, 2018; August 24, 2018; October 16, 2018. The images were collected using an AisaKESTREL compact hyperspectral pushbroom sensor.Provided in the AEHYPWRNE1M product are 178 hyperspectral bands that have been radiometrically, geometrically, and atmospherically corrected.
