VNP43IA1: BRDF/Albedo Model Parameters Daily L3 Global 500m SIN Grid

  • The Suomi NPP VIIRS VNP43IA1 product provides kernel weights at 500m resolution for modeling Earth's surface anisotropic effects.

  • This product is generated daily using 16 days of VIIRS data and offers three spectrally dependent kernel weights.

  • VNP43 data products are designed to ensure continuity with NASA's MODIS BRDF/Albedo data product suite.

  • The dataset is available from 2012-01-17 to 2024-06-09 with a daily cadence.

  • Data are freely accessible from LP DAAC NASA, with a request to cite the datasets when used in publications.

Description

The Suomi National Polar-Orbiting Partnership (Suomi NPP) NASA Visible Infrared Imaging Radiometer Suite (VIIRS) Bidirectional Reflectance Distribution Function (BRDF) and Albedo Model Parameters (VNP43IA1) Version 1 product provides kernel weights (parameters) at 500 resolution. The VNP43IA1 product is produced daily using 16 days of VIIRS data, temporally weighted to the ninth day, which is reflected in the file name. The VNP43IA1 product provides three spectrally dependent kernel weights, also known as model parameters: isotropic (fiso), volumetric (fvol), and geometric (fgeo), which can be used to model anisotropic effects of the Earth's surface. All VNP43 data products are designed to promote the continuity of NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) BRDF/Albedo data product suite.
