CLAD Scientific Work Groups

Scientific working groups (WGs) have been a component of CLAD since 2011. The objectives of WGs are to increase our understanding and ability to estimate and represent critical loads of deposition in the United States. To date, two sets of WGs have been established by CLAD.

FOCUS project (2011-2015) – developed the CLAD National Critical Load Database (NCLD) and established eight WGs focused on improving forest ecosystem, lichen, surface water, empirical and biodiversity critical loads. See FOCUS for additional information

CLAD WGs (2016-current) – four WGs to advance estimation and representation of critical loads in the United States:

  • WG-1: Adding new data and critical loads to the CLAD NCLD
    • produce, adopt, and practice a standardized method for review and incorporation of new published data and critical loads into the NCLD
    • Contact: Jason Lynch
  • WG-2: Characterizing uncertainty in critical load estimates
  • WG-3: Synthesizing multiple critical loads
    • develop a repeatable and defensible method for representing multiple critical loads in the same geographical area
    • Contact: Christopher Clark and Linda Pardo
  • WG-4: Deposition uncertainty
    • develop an understanding of the range of uncertainty that is associated with measured versus modeled deposition and how it relates to critical loads
    • Contact: Michael Bell
