G.8            Reference data

NRLMSISE­00 altitude profiles at equatorial latitude of temperature, and number densities (concentrations) are listed in Table G-1, Table G-2, and Table G-3 for low solar and geomagnetic activities (F10.7 = F10.7avg = 65, Ap = 0), moderate solar and geomagnetic activities (F10.7 = F10.7avg = 140, Ap = 15), and high long term solar and geomagnetic activities (F10.7 = F10.7avg = 250, Ap = 45), respectively. The tables cover both homospheric and heterospheric altitudes from ground level up to 900 km, averaged over diurnal and seasonal variations. Figure G-1, illustrates the altitude profile of the temperature. Figure G-3 shows the atomic oxygen number densities at low, moderate and high long term activity conditions. For moderate activity levels, Figure G-4 shows the logarithmic number concentration profiles of the main atmospheric constituents.

A JB-2006 altitude profile of total density at equatorial latitude is listed in Table G-4 and plotted again in Figure G-2 for

                low solar and geomagnetic activities              
(F10.7 = F10.7avg = 65, S10.7 = S10.7avg = 60, M10.7 = M10.7avg = 60, Ap = 0)

                moderate solar and geomagnetic activities  
(F10.7 = F10.7avg = 140, S10.7 = S10.7avg = 125, M10.7 = M10.7avg = 125, Ap = 15)

                high long term (27 days or longer) solar and geomagnetic activities  
(F10.7 = F10.7avg = 250, S10.7 = S10.7avg = 220, M10.7 = M10.7avg = 220, Ap = 45)

                and high short term (daily) solar and geomagnetic activities               
(F10.7 = 300, F10.7avg = 250, S10.7 = 235, S10.7avg = 220, M10.7 = 240, M10.7avg = 220, Ap = 240)

                The subscript ‘avg’denotes the 81-day average.

These values have been averaged over diurnal and seasonal variations.
