Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

NSF lists this award's end date as 31 July 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 November 2029.

Abstract

Thunderstorms that develop at night, also known as nocturnal convection, are a difficult forecasting challenge. As the surface cools after sunset, the temperature and moisture in the lowest layer of the atmosphere can sort into complex layers, which can either favor or suppress the potential for thunderstorms. This project will apply new techniques for incorporating ground-based remote sensing measurements into…
