The USA National Phenology Network (USA-NPN; www.usanpn.org) collects, stores, and shares phenology data, maps, and information to support scientific discovery and management decisions. The USA-NPN provides real-time maps and short-term (6-day) forecasts of the biological start of spring and accumulated growing degree days. Accumulated temperature, often calculated in growing degree days, is a commonly used metric for predicting the timing of phenological transitions in plants and animals. Map products offered by USA-NPN also include long-term (1981-2010) average conditions as well as anomaly maps.
The data and map products offered by the USA-NPN are available through an online visualization tool (www.usanpn.org/data/visualizations), for download as images and raster files (www.usanpn.org/data/phenology_maps), and through OGC compliant web services for use in geospatial analysis. In this presentation, I will introduce the various map products and demonstrate how to access them for use in broadcast communications.
