AVHRR Global Production Efficiency Model (GloPEM)

Data Access

The GloPEM (Global Production Efficiency Model) data set is available from 1981 to 2000 in ten-day periods or summed annual products. The data set is derived from the Advanced Very High Resolution Radiometer (AVHRR) images at an 8km resolution from the AVHRR Pathfinder Project. The objective of GloPEM research is to provide a basis for modeling and monitoring terrestrial net primary production and gross primary production at the global scale.
