The data produced at LTER sites are an extraordinary scientific resource that can inform a wide variety of questions. Among-site comparisons interrogate the generality of effects observed at particular sites. Modeling efforts employ long term observations and experiments to formulate and test rigorous descriptions of theory. Scaling exercises get at the continental or even global impacts of documented effects. LTER synthesis working groups organized through the LTER Network Office (LNO) are intended to support collaboration on these and many other types of questions. In the 2022 competition, the LNO expects to award 2-4 synthesis working groups at a funding level of up to $110,000 for up to two years. Required proposal elements and instructions are below.

Proposals are due October 12, 2022 at 5:00 p.m. PDT.

What makes a synthesis working group?

LTER synthesis working groups do:

  • analyze and synthesize LTER data
  • employ data from multiple sites (The archive of LTER data is freely available and searchable at the Environmental Data Initiative.)
  • involve individuals who are familiar with the sites and data
  • draw on publicly available data
  • make derived data products publicly available
  • strive to follow best practices for reproducible science

LTER synthesis working groups may:

LTER synthesis working groups do not:

  • collect new data
  • fund salaries
