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

  1. NSF lists this award's end date as 31 March 2029.
  2. NSF rules say the final report is due no later than 120 days after that.
  3. So the final report is due by 29 July 2029.

Abstract

Earth’s upper atmosphere emanates a faint luminescence known as airglow. This non-thermal radiation occurs at altitudes from about 50 to 300 km and is initiated by solar radiation absorbed by atmospheric constituents. Light emission observed during the day is called dayglow. A plethora of photochemical processes and excitation pathways persist through the night and collectively result in emission called nightglow.…
