Tropical cyclones revolve around the interactions of processes that occur at various spatial and temporal scales. Studying these processes and their interconnections require the consolidation of various data that capture these processes at their respective scales. Such data consolidation is no easy task, as they involve obtaining, collocating, and intercalibrating data from various sources and products; ensuring data homogeneity over the period of the dataset; and standardizing these various data sources for a straightforward analysis. To advance the understanding around the relationship between the tropical cyclone convective structure and the environment, we develop the Tropical Cyclone Precipitation, Infrared, Microwave, and Environmental Dataset (TC PRIMED). TC PRIMED contains tropical cyclone-centric 1) intercalibrated, multichannel, multisensor microwave brightness temperature, 2) retrieved rainfall from NASA’s Goddard Profiling Algorithm (GPROF), 3) nearly coincident geostationary satellite infrared brightness temperatures and derived metrics, 4) tropical cyclone position and intensity information, 5) ECMWF fifth-generation reanalysis fields and derived environmental diagnostics, and 6) precipitation radar observations from the TRMM and GPM Core Observatory satellites.TC PRIMED consists of over 245,000 overpasses of 3,585 tropical cyclones from 1987 through 2024, providing researchers with an analysis-ready dataset to promote and support research and forecast product development. In this talk, I will summarize the efforts to create TC PRIMED and increase its artificial intelligence readiness, and present the research that were enabled by the development of TC PRIMED.
