The Office of Science and Technology Integration (STI) performs portfolio management for planning, research and development, and integration efforts for science and technology improvements across the NWS.
STI analyzes requirements for service improvements from NWS field offices and National Centers through close coordination with the AFS Office; develops potential scientific and technological solutions through coordination with partners within NOAA and with the external research community; and sponsors applied research and development of programs/projects to address these requirements. Major research and development areas of the Office include, but are not limited to, improvement of operational atmosphere, ocean, land, sea ice, hydrological and other components of environmental prediction models, operational guidance and decision support tools, and social science integration.

The Office also establishes priorities for and oversees collaborative and applied research and development activities within NWS, in coordination with other NWS offices and NOAA line offices, as well as the research community. The Office provides a centralized coordination and management of field-driven innovation and research to operations transition programs and processes. These include but not limited to, testbeds, operational proving ground; the Science Operations Officer (SOO) and Development and Operations Hydrologist (DOH) Program; Collaborative Science, Technology, and Applied Research (CSTAR) Programs; as well as cross- cutting STI projects including social science integration and training.

The Office collaborates with the Central Processing and Dissemination offices to maintain and enhance a centralized research, development, and testing environment, which enables transitioning research to operations through streamlining development, testing, training and field implementation.

Meteorological Development Laboratory (MDL)

The Meteorological Development Laboratory (MDL) conducts and sponsors applied research and development for the improvement of diagnostic and prognostic weather information; data depiction and utilization; warning and forecast product preparation; and data and forecast evaluation. Projects involve modern physical, dynamical, and statistical techniques implemented on operational computers. Emphasis is placed on integrated suites of guidance and final products for Weather Forecast Offices, River Forecast Centers, and National Centers. The Laboratory collaborates with other laboratories and centers within and outside of NOAA and actively seeks to identify new techniques in response to NWS mission requirements. The Laboratory provides meteorological support to other elements of the Office of Science and Technology, as required.

STI Modeling

The STI Modeling Program Team is responsible for supporting a variety of NWS modeling and research initiatives to improve weather forecasts. This is accomplished by funding research and education projects to accelerate and advance the development of new models, and foster collaboration among NOAA research scientists, federal labs, operational forecasters and the academic community. Examples of programs managed by this program division include efforts to improve guidance for hurricane track, intensity, and storm surge forecasts; develop an end-to-end air quality forecast capability; advance research to extend forecast skill beyond 8-10 days; and implement a weather-scale, fully-coupled numerical weather prediction system.

Research to Operations (R2O)

The STI Field Driven Research to Operations (R2O) Team is responsible for coordination and management of NWS field-driven innovation and research to operations transition programs. The team works closely with the NWS regional Scientific Services Divisions (SSDs), Office of Water Prediction and NCEP service centers to organize and facilitate projects with Science and Operations Officers (SOOs) and Development and Operations Hydrologists (DOHs) to integrate new or improved science and technology into field operations. The team also provides programmatic support to major NWS R2O initiatives in several areas including aviation weather, lightning, fire weather, and climate.

Operational Proving Ground (OPG)

The Operational Proving Ground (OPG) facilitates testing of advanced operations, services, and science and technology (S&T) capabilities which address the needs of both internal and external users. By creating a streamlined research-to-operations (R2O) and operations-to-research (O2R) process, an iterative, two-way interaction between S&T development and NWS operations is optimized. To be considered for operational implementation, candidate capabilities must successfully introduce a new or enhanced operational capacity with no appreciable negative impact on existing systems and practices. Particular emphasis is placed on applications which demonstrate substantive improvement to one or more of the following: the warning and forecast process, collaborative decision making, risk communication, and/or provision of impact-based decision support services.

Current STI Grants

STI provides funding and oversight to numerous research projects through the NGGPS, HFIP, and CSTAR Programs. Most of these projects are collaborative efforts between university researchers and NOAA scientists.
