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

How we got this date

NSF lists this award's end date as 30 June 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 October 2028.

Abstract

On clear nights, colder air slides downhill under gravity, which is called a slope flow. Slope flows occur in a layer of air near the ground where air density decreases with height. This condition is called stable stratification. In stable stratification, buoyant forces resist vertical motion. Such conditions are common at night and in polar regions. Stable stratification controls mixing of heat and pollutants near…
