Lilac in full bloom- a phenophase recorded in many historical datasets.

Access historical data sets

There are three ways to access phenology data sets through the USA-NPN: 

  • View data sets records submitted through the USA-NPN data set registry tool.
  • Use the USA-NPN Mercury Search Engine This meta database contains information about phenology data sets, including the meta database previously housed at the University of Wisconsin-Milwaukee and metadata records extracted from the National Biological Information Infrastructure Metadata Clearinghouse.
  • View the National Climatic Data Center's Phenology Records This resource includes a number of phenological and related information data sets available for downloading, including: 1) North American first leaf and first bloom lilac data from 1956-2003; 2) French records of grape-harvest dates in Burgundy used to reconstruct spring-summer temperatures from 1370 to 2003; 3) Winter half-year temperature reconstruction for the middle and lower reaches of the Yellow River and Yangtze River, China, during the past 2000 years; 4) Weighted annual means for the flowering of cherry and apple tree and budburst beech from plant phenological observations across a range of sites in Switzerland from 1702 to 2005; and 5) A 280-year composite series (includes a set of 14 different records) of the flowering of cherry trees from 1721-2000 in Switzerland.
