Subject Matter Expert Review Panel on Nitrogenous Emissions from Soils: Final Report Completed with Public Workshop Anticipated late June 2025
The California Air Resources Board (CARB) invites you to participate in a public workshop to review the Final Report for the Soil Nitrogenous Emissions "Subject Matter Expert Review Panel (SMERP)" Contract (23RD017). As part of the SMERP, Dr. William Horwath (University of California [UC] Davis), Dr. Whendee Silver (UC Berkeley), Dr. Xia Zhu-Barker (University of Wisconsin -Madison), Dr. Martin Burger (California Department of Food and Agriculture [recently retired]; UC Davis), and Dr. Viney Aneja (North Carolina State University) conducted a comprehensive review of scientific literature, pertinent databases, and emission estimation methodologies that pertain to nitrogenous emissions from soils.”
Subject Matter Expert Review Panel on Nitrogenous Emissions from Soils
CARB is seeking five technical experts to serve in the Subject Matter Expert Review Panel (SMERP) that will independently evaluate existing data and science to improve our current understanding of nitrogenous emissions, including oxides of nitrogen, nitrous oxide, and ammonia, from soils, particularly in California.
Interested parties are encouraged to nominate their peers or apply themselves to be a member of the SMERP. Self-applicants must fill out the Conflict-of-Interest (COI) section prior to submission. Otherwise, CARB staff will contact the nominees to collect such information prior to SMERP member selection. Complete and submit this Form to abhishek.dhiman@arb.ca.gov by the deadline on 8/21/2023 at 5:00 PM PDT.
Panel de Revisión de Expertos en la Materia sobre Emisiones Nitrogenadas del Suelo
CARB está buscando cinco expertos técnicos para trabajar y ser parte del Panel de Revisión de Expertos en la Materia (SMERP, por sus siglas en Ingles) que evaluarán de forma independiente los datos y la ciencia existente para mejorar nuestra comprensión actual de las emisiones nitrogenadas, que incluye los óxidos de nitrógeno, el óxido nitroso y el amoníaco, de los suelos, en particular en California.
Se le anima a las partes interesadas que nominen a colegas o apliquen para ser miembros del SMERP. Los autosolicitantes deben completar la sección de Conflicto de Intereses (COI). De lo contrario, el personal de CARB se comunicará con los nominados para recopilar dicha información antes de la selección de los miembros de SMERP. Complete y envíe este formulario a abhishek.dhiman@arb.ca.gov antes de la fecha límite del Agosto 21 de 2023 a las 5:00 PM PDT.
