资源简介：
The VNP18C2 Version 2 is a NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Photosynthetically Active Radiation (PAR) Level 3 CMG product produced at 0.05 degree pixel resolution at daily intervals. PAR is incident solar radiation in the visible spectrum (400-700 nanometers) and is an important variable in land-surface models that address a variety of scientific and application issues.
The VNP18 algorithm adapts the narrowband look-up table (LUT) approach to estimate DSR. The LUTs consider different types of loadings of aerosols and clouds at a variety of illumination/viewing geometry. Additional details regarding the methodology used to create the data are available in the Algorithm Theoretical Basis Document (ATBD).
The VNP18C2 product is aggregated from VNP18A2 files and includes one set of global 3-hour PAR variables and one set of daily mean PAR.
