(e) Program plan Not later than 180 days after the date of the enactment of this Act, the Under Secretary shall develop a plan that details the specific research, development, data acquisition, and technology transfer activities, as well as corresponding resources and timelines, necessary to achieve the goal of the program under subsection (b). (f) Annual budget for plan submittal After the development of the plan pursuant to subsection (e), the Under Secretary shall, not less frequently than annually, submit to Congress a proposed budget corresponding with the activities identified in such plan. 206. Aviation weather and data innovation (a) Program The Under Secretary shall maintain an airborne observation program (in this section referred to as the program ) for the acquisition of atmospheric sensor data and the deployment of critical atmospheric sensors, including in partnership with the weather enterprise. (b) Activities The program shall include activities that carry out the following: (1) Procurement of weather data available from commercial aircraft, as determined by the Under Secretary. (2) Acquisition of additional vertical profile observations that provide spatial and temporal density, as determined by the Under Secretary. (3) Analysis of procured data when incorporated into the National Oceanic and Atmospheric Administration’s unified forecast system in order to provide improved forecast information for aircraft. (c) Budget The Under Secretary shall, not less frequently than annually, submit to Congress a proposed budget corresponding with the activities described in subsection
