Visitors: From Innovations to Operations, the DTC Visitor Program Stimulates Progress

Visitor Program: An Overview

Spring 2022 | Since 2004, one of the hallmarks of the Developmental Testbed Center (DTC) has been its visitor program. The DTC Visitor Program provides an opportunity for DTC staff and our operational partners to strengthen ties with the research community, which is critical to the success of the DTC’s mission. It began informally when four scientists were invited to work with us for one month over the summer on a project of their choice. The only stipulation was that it had to be consistent with… Read More

Community Connections: The GeneralIzed Aerosol/chemistry iNTerface (GIANT)

Workshop and Hackathon

Spring 2022 | An Earth System Model (ESM) is a model that represents various domains of the earth, such as atmosphere, ocean, sea ice, etc. A new community effort is underway to devise a method to transfer information easily and consistently between chemistry and aerosol modules, and other components of ESMs. Currently, it is difficult to study and quantify feedbacks of chemistry/aerosol parameterizations on weather and climate because of the structurally diverse ways in which chemistry/aerosols… Read More

Did you know?: New US Council for Interagency Coordination of Meteorological Service

Spring 2022 | In April 2017, the President signed into law the Weather Research and Forecasting Innovation Act. This Act required establishing an Interagency Committee for Advancing Weather Services -- The Interagency Council for Advancing Meteorological Services (ICAMS) meets this requirement.
