Physical parameter description

Temperature Tn obtained by Fabry-Perot Spectrometer at 250 km (Arrival height, Antarctica; Resolute Bay, Canada)

Model output file format:
Year DOY Hour Min Sec Lat [deg] Lon[deg] Height[km] Tn[K]
Neutral temperature T_n at 250 km height obtained by the Fabry-Perot Spectrometer at Arrival heights, Antarctica (only for E.2005.190 event) and Resolute Bay, Canada (only for E.2006.348 event)

Here DOY is day of year, and Hour, Min, Sec are universal time. Height[km] is 250 km which corresponds to the emission peak for atomic oxygen red line (630 nm). Tn[K] represents neutral temperature in kelvin. There are measurements from 5 observation look directions at Arrival heights the geographic locations (lat, lon) become

N (-72.60, 166.67)
W (-77.83, 142.62)
S (-83.06, 166.67)
Z (-77.83, 166.67)
E (-77.83, 190.72).

Also, the geographic locations (lat, lon) from the 5 directions at Resolute Bay are

N (76.98, -94.89)
W (74.73, -103.42)
S (72.48, -94.89)
Z (74.73, -94.89)
E (74.73, -86.36)

Lat [deg] and Lon [deg] are geographic location of one of ten geographic locations shown above.
