Input:

• z - solar zenith angle in degrees
• it - season (month)
• f - F10.7 solar radio flux (daily)
• vKp - Kp magnetic index (3-hour)
• f5SW - indicator for Stratospheric Warming (SW) conditions =0 no SW, =0.5 minor SW, =1 major SW
• f6WA - indicator for Winter Anomaly (WA) conditions =0 no WA, =0.5 weak WA, =1 strong WA

Criteria for SW and WA indicators:

• SW minor: Temperature increase at the 30 hPa level by 10 deg.
• SA major: The same but by 20 degrees.
• WA weak: An increase of the absorption in the 2-2.8 MHz range at short A3 paths by 15 dB
• WA strong: The same by 30 dB.

Only for month 12 to 2 (winter).

Output:

• numpy array of electron density [m-3] at h=60,65,70,75,80,85, and 90km
