I have some exciting news to share with you! Phenology information is being used in a national climate change indicator. Now is a great time to learn more about future plans for data collected and curated by the USA-NPN in the recently released Data Product Delivery Framework and Catalog document.  Read more about both of these new developments below.

As a member of the phenology community of practice, we would love to hear from you on how you we can facilitate your use of USA-NPN data for your research and management applications. We look forward to growing and cultivating this community with you! 


 
   
 
What's new at the USA National Phenology Network
"Start of Spring" among 14 indicators released by USGCRP

 

The US Global Change and Research Program released the first 14 indicators of climate change on Wednesday, May 5, 2015. Among these is the Start of Spring indicator, which reflects the accumulation of heat sufficient to initiate leafing and flowering in temperature-sensitive plants. The Start of Spring indicator is calculated and validated using data and models curated by the USA-NPN, including observations of plant leaf-out and flowering collected via Nature's Notebook.

Visualization Tool... coming soon! 

 

The new USA-NPN Visualization Tool is almost complete and is anticipated to launch in June. This tool offers significant enhancements over the previous version, and will allow you to explore spatial and temporal phenology data resources and trends. 

 

Save the date! On July 14th we will host a webinar to introduce the tool and demonstrate its many functions. Webinar time is 2pm Eastern, 1pm Central, 12pm Mountain, 11am Pacific & AZ.

Looking for more phenology data?

 

Did you know we also maintain a listing of phenology datasets that were collected following other protocols? Check out the USA-NPN phenology dataset search tool where you can search for phenology data not housed in the National Phenology Database.

 

You can also contribute your own dataset as a valuable resource to the phenology research community!

Phenology data curated by USA-NPN shows importance of daytime temperature

Piao et al (2015) used in-situ and satellite data from both Europe and the United States and found that daytime temperature (Tmax) was a more important trigger for leaf unfolding than nighttime temperature (Tmin).  This study utilized long-term cloned lilac phenological observations housed in the National Phenology Database. These results can improve Earth system models. 

Phenopix R package now available!

Are you collecting phenology data using phenocams? A new R package is available to analyze digital photography imagery. The package phenopix provides functions to process digital images of vegetation cover, depict greenness index trajectories, and extract relevant phenological stages.
