For a decade and a half, US CLIVAR has promoted the concept of Climate Process Teams (CPTs). CPTs improve the fidelity of coupled climate models by facilitating the transfer of knowledge from observational and process-oriented research to the development of physical process representation in component ocean or atmosphere global climate models (GCMs). A CPT, as defined by US CLIVAR, is a:
funded multi-institutional project that assembles observation-oriented experimentalists, process modelers, process diagnosticians, theoreticians, and climate model developers from two or more modeling centers into a single project that focuses on a specific process or set of processes to assess model sensitivities to process uncertainties, establish observation and model metrics, and develop, test, and implement parameterization improvements.
NSF, NOAA, and DOE have co-sponsored three rounds of CPT projects, with the latest projects funded in FY2019.
In 2015, the US CLIVAR Process Studies and Model Improvement (PSMI) Panel organized a review of CPTs to assess the effectiveness and lessons learned from the CPT approach, main sources of errors/biases in models, opportunities for future model improvement, and potential payoff for future CPT projects. The review committee collected input through questionnaires of seven US modeling center and numerous observational programs, process studies, CPT projects, and US CLIVAR Working Groups, followed by an open community workshop held at NOAA GFDL in September 2015. The information collected informed a 2016 US CLIVAR White Paper.
Below are the key findings from the white paper, best practices for a CPT, and how best to propose a CPT project to the US CLIVAR funding agencies.
It should be noted that CPTs are just one tool among many program and modeling center mechanisms for model improvement.
See Ten tips for building an effective CPT for additional best practices guidance.
NSF Physical Oceanography (PO) and Climate & Large-scale Dynamics (CLD) Programs are open to receiving proposals that address improving the representation of processes (rather than improving biases) in the NCAR CESM and component community models. The concept for CPTs has been effectively socialized within the research community and does not necessitate a specific solicitation or Dear Colleague Letter. Instead, interested parties should contact the program managers with a brief one-page outline describing the concept and potential participants to help facilitate cross-agency coordination.
NOAA is interested in CPT projects with a traditional focus on model diagnostics and process representation improvements that include collaborations with the NOAA global coupled modeling centers. The NOAA Climate Variability and Predictability (CVP) and Modeling, Analysis, Predictions and Projections (MAPP) Programs will consider support for scientists at NOAA labs, centers, NOAA OAR Cooperative Institutes, and academic research institutions. Awards may be funded in partnership with other agencies participating in US CLIVAR and/or the US Global Change Research Program. NOAA collaborating scientists and those interested in NOAA support should contact Sandy Lucas, NOAA CVP, or Annarita Mariotti, NOAA MAPP, for guidance. The current FY19 NOAA funding opportunity seeks proposals for CPTs.
NASA is interested broadly in Earth system modeling with an observational focus and collaboration with NASA GMAO and/or GISS modeling centers. A possible NASA solicitation would be a few years away. In the near term, the NASA Modeling, Analysis, and Prediction (MAP) could provide core-funded participation of scientists at its centers in CPTs. If there is center interest, PIs should consult with David Considine, NASA MAP, at the proposal stage. NASA Physical Oceanography (PO) will consider funding a postdoc at a university or NASA lab (e.g., JPL) for interaction with NASA on a CPT project proposed to another program’s call. Interested PIs should consult with Nadya Vinogradova-Shiffer, NASA PO, at the proposal stage.
DOE is interested in focused projects to engage program priority interests and advance the development and evaluation of the E3SM model (e.g., land/ocean model development, high-resolution data assimilation, coupled modeling, development of process-based metrics for evaluation). DOE does not plan to have a focused CPT call for 2018. DOE modeling programs could support DOE lab scientists collaborating on other agency-sponsored CPTs through base funding. Interested lab scientists should consult with Renu Joseph, DOE EESM, at the proposal stage.
ONR is interested in modeling of subseasonal-to-interannual timescale processes and the collaboration of Navy model development (e.g., NAVGEM, HYCOM) and Naval Research Laboratory (NRL) scientists. ONR can consider supporting the participation of NRL scientists on CPT projects proposed to other agencies. PIs should consult with Scott Harper, ONR, at the proposal stage.
