Fire Information and Reaction Enhancement Act of 2023 or the FIRE Act of 2023 This bill establishes certain programs to improve wildfire forecasting and detection within the National Oceanic and Atmospheric Administration, including the development of weather research testbeds. (Testbeds are collaborative spaces where researchers and forecasters work alongside each other to integrate new systems into models, test and streamline data assimilation methods, and otherwise improve weather products and services for the benefit of the public.)
