VNP09H1: VIIRS Surface Reflectance 8-Day L3 Global 500m

  • The VNP09H1 product provides an 8-day composite of land surface reflectance from the Suomi NPP VIIRS sensor at 500m resolution.

  • Reflectance data is atmospherically corrected and includes quality assurance layers for cloud state, land/water, and aerosol conditions.

  • The dataset covers the period from January 19, 2012, to November 24, 2024, and is freely accessible from NASA LP DAAC.

  • Imagery bands I1, I2, and I3 estimate land surface reflectance and are accompanied by quality control and state quality assurance bands.

  • Users are requested to cite the dataset appropriately when publishing results based on this data, with links and guidance provided.

Description

The 8-day Visible Infrared Imaging Radiometer Suite (VIIRS) Surface Reflectance (VNP09H1) Version 1 composite product provides an estimate of land surface reflectance from the Suomi National Polar-orbiting Partnership (Suomi NPP) VIIRS sensor for three imagery bands (I1, I2, I3) at nominal 500m resolution (~463m). The 500m dataset is derived through resampling the native 375m VIIRS resolution in the L2 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, which is selected on the basis of high observation coverage, low sensor angle, the absence of clouds or cloud shadow, and aerosol loading. The three reflectance bands, this product includes a state quality assurance (QA) layer and a reflectance band quality layer.
