Mar 1, 2026March 2026 achievements focused on refreshing the data foundation, extending FluSight capabilities, and stabilizing reporting processes to enable timely, data-driven decisions. Core data refreshes updated time-series and hubverse/target datasets for 2026-03, ensuring near-term forecast accuracy. FluSight outputs, ensembles, and weekly/ED artifacts were generated for the March cycle, improving forecast visibility and operational decision support. Model/config updates (Ens_q_cat_sub and FluSight YAML) enhanced fidelity and deployment consistency. Data pipelines and outputs advanced with dist_cat forecasts, new ensembles, and q_cat_sub updates (03-14 to 03-28), complemented by automated weekly summaries and ED reports. A disciplined maintenance regime (cleanup of deprecated data and general fixes) reduced data debt and improved stability.
