Abstract:

Phosphorus is a limited resource and a critical element in biogeochemistry. The raster datasets included here were created to show the spatial distribution of phosphorus stocks, accumulation, and throughput in the Central Arizona Phoenix Long Term Ecological Research study area. These rasters were created as the products of a phosphorus budget compiled within the CAP-LTER study area and are intended to be used by researchers studying biogeochemical cycles and sustainability. The raster of phosphorus stocks show the distribution of both abiotic and biotic phosphorus pools in the environment, which generally have long residence in the urban ecosystem. The accumulation and throughput raster show the likely areas where phosphorus will aggregate (inputs-outputs) over time and throughput shows areas with the highest inputs plus outputs of P. In addition to our final products we also include rasters used as variables to calculate the raw stocks, accumulation, and throughput rasters.
