The maps show NPP for the period 1951 to 2000 based on datasets from CRU and GPCP VASClimO. High resolution maps of NPP (5minx5min) as GeoTiffs are available here for download. DIFFERENCES BETWEEN THE 1951-1975 and 1976-2000 PERIOD: Differences in climatic npp between the 1951-1975 and 1976-2000 period appear in some regions of the world. The data shows the latitudinal dependence of these differences. It demonstrates that npp would have increased for most latitudes if temperature were the limiting factor. However, especially between 0 and 20 degrees North the npp decreased because of its precipitation dependency. High resolution images of the differences in npp between 1951-1975 and 1976-2000 for the CRU/VASClimO dataset are also provided here as GeoTIFF for download. CLIMATIC SENSITIVITY OF NPP: The sensitivity of NPP with respect to changes in annual mean temperature dNPP/dT and annual mean precipitation dNPP/dP has been calculated for each location on earth. High resolution GeoTIFF images on sensitivity of net primary production NPP in g(dry matter)/m2/year with respect to changes in annual mean precipitation and annual mean temperature are also available for download in the Distribution Info section of this form.
