The Developmental Testbed Center (DTC) is a partnership between the National Oceanic and Atmospheric Administration's (NOAA), US Air Force and NSF National Center for Atmospheric Research (NCAR). The DTC is a multi-institutional organization whose staff are primarily affiliated with the NSF NCAR Research Applications Laboratory (RAL) and the NOAA Global Systems Laboratory (GSL).
The DTC offers visitor appointments through the DTC Visitor Program. The program supports visitors to collaborate with the DTC to test, evaluate and improve forecasting tools, verification techniques, or model components of weather forecasting systems, with the ultimate goal of facilitating the transition of innovations or advancements to operational forecasting systems run by the National Centers for Environmental Prediction (NCEP) and Air Force (AF).
Prospective visitors are required to submit a proposal. Selected visitors will have a year to complete their project beginning on a mutually agreed upon start date, where some portion of the work can be conducted from their home institution. The program offers two types of projects: 1) projects undertaken by the Principal Investigator (PI), and 2) projects undertaken by a graduate student advised by the PI. The general parameters for these two types of projects are described below. To accommodate each visitor’s situation with flexibility, we encourage prospective visitors to contact us to determine whether a variant of these general parameters would be acceptable before submitting a proposal.
Projects by PI
Successful applicants for this type of project can request travel, per diem and an honorarium to work with the DTC staff and/or staff at one of the operational centers for up to two months. It is possible to distribute the two months of support over multiple visits, within reason, during the one-year period [Tips: Some past visitors have found it useful to plan an initial visit early in their visitor appointment, a second visit in the middle of their visitor appointment and a final visit near the end of their appointment, where the total number of travel days across the three trips is no more than two months]. Honorarium support is possible for some remote work at the visitor’s home institution. Support to attend conferences and publication costs related to the project may be requested.
Federal employees are not eligible for financial support through the DTC Visitor Program, and should contact the DTC Director Louisa Nance (nance@ucar.edu) to discuss other avenues for collaborating with the DTC.
Projects by a graduate student advised by the PI
Successful applicants for this type of project will be offered up to one year of living per diem stipend and travel expenses for the graduate student to work with the DTC staff and/or one of its partners [e.g., NCEP's Environmental Modeling Center (EMC)], and up to two weeks of travel and per diem for the project PI to visit the location of the graduate student. The graduate student is welcome to come for multiple shorter visits, within reason, over the one year period. Support to attend conferences and publication costs related to the project may also be requested.
This announcement is for an opportunity to work with the DTC to evaluate operational modeling systems in order to assess/identify deficiencies, evaluate new modeling technology that shows promise of improving weather forecasts within the next two to six years, or provide the DTC with promising new technology for research applications in accordance with chartered focus areas. We encourage interested parties to contact us by emailing visitor-program@dtcenter.org prior to submitting a proposal to discuss whether your project will be a good fit, particularly if the scope falls outside of the suggestions below.
Projects are particularly encouraged for model improvement and/or testing and evaluating new modeling, forecast, and verification technologies, such as:
The DTC develops and maintains two software tools that are core to its testing and evaluation activities: METplus (https://dtcenter.org/community-code/metplus) and CCPP (https://dtcenter.org/community-code/common-community-physics-package-ccpp) along with its companion single-column model (SCM). These tools facilitate Hierarchical System Development (HSD; cf. https://ufscommunity.org/articles/hierarchical-system-development-for-the-ufs/) for Earth System Modeling (ESM) systems such as the Unified Forecast System (UFS). HSD involves testing small elements of an ESM first in isolation, then progressively connecting these elements with increased coupling between ESM components.
Projects are encouraged that enhance these two software tools and/or the HSD framework, such as
Potential topics of interest are outlined in Section 1. These topics are general and are intended as suggestions for the type of projects we will consider. Proposals for participation in the DTC Visitor Program should provide details on the specific work the visitor would conduct with the DTC and/or one of its partners (e.g., EMC). Previous DTC visitors are welcome to submit proposals for new projects or projects that build on past work. All proposals will be subjected to the same review process (see description below). The submitted material should include the following:
As noted above, it is expected that the visitor will spend a residency of no more than two months (twelve months for a graduate student project) at the DTC, an operational center or a combination of time at the DTC and an operational center. The total duration of the project can continue for one year. It is expected that visitors will be able to continue their work from their own institution using DTC computational resources. We do allow for some flexibility within the general guidelines and encourage prospective visitors to contact us to discuss their ideas and configuration of their visit prior to applying.
Proposals in response to this announcement should be submitted through an online application form at: https://dtcenter.org/visitor-program/application.
Proposals submitted in response to this announcement will be subject to both internal and external review. The external review will be conducted by the DTC Science Advisory Board (SAB), which consists of scientists from government labs, operational centers, and academic institutions. The DTC Management Board will make the final decision based on recommendations to the DTC Director from the review by the DTC SAB. Focus categories for which the reviewers are asked to rate proposals include:

The DTC Visitor Program supports visitors to work with the DTC to test new forecasting and verification techniques, models and model components for numerical weather prediction (NWP). The goal is to provide the operational weather prediction centers (e.g., NCEP and AFWA) with options for near–term advances in operational weather forecasting, and to provide researchers with NWP codes that represent the latest advances in the technology. This program also offers an opportunity for visitors to introduce new techniques into the DTC Community Codes that would be of particular interest to the research community. The DTC offers two types of visitor projects: 1) projects undertaken by the Principal Investigator (PI), and 2) projects undertaken by a graduate student under direction of the PI. Successful applicants for the first type of project will be offered up to two months of salary compensation, and travel and per diem. The two months can be distributed over several weeks during a one–year period. Visitors are expected to visit the DTC in Boulder, Colorado and/or one of the operational centers. Access to DTC computational resources will enable significant portions of the visitor's project to be conducted from their home institution. Successful applicants for the second type of project will be offered up to one year of temporary living per diem stipend and travel expenses for the graduate student to work with the DTC in Boulder, Colorado, and travel and per diem for up to two two–week visits to the DTC by the project PI.
Proposals submitted in response to the DTC Visitor Program Announcement of Opportunity are subject to both external and internal review. The external review will be conducted by the DTC Science Advisory Board (SAB), which consists of scientists from government labs, operational centers, and academic institutions. The DTC Management Board will make the final recommendations to the DTC Director based on the review by the DTC SAB.
