3. Global Wind Profiler Satellite
What is GLOWIN?

4. Idea / Principle Wind Profiler t = 2*d/c WIND MICROWAVES
(λ = 60cm, 3m)
d (distance)
t = 2*d/c
(c : light speed)

5. GLOWIN
Idea / Principle
3 directions
- Forward
- Leftward
- Rightward

6. Details Orbit (LEO) H (altitude) = 200 km d (distance) = 1.6E+3 kmRE d H
ME = 5.98E+24 kg
RE = 6400 km
G = 6.673E-11 Nm2/kg2
H (altitude) = 200 km
d (distance) = 1.6E+3 km
v (velocity) = 7.8E+3 m/s
T (period) = 5.3E+3 sec = 1.47 hr
1day → 16.3 cycles

7. Details 2 millions cells × 3-dir Resolution d = 1600 km 2500 km 2 km

8. Details Why 3 Directions?
Observed values from 3 directions → Interpolation → Reliability ↑
Because of Land topography

9. We can See..

Interaction Information - Atmospheric Phenomena ↔ Ocean Phenomena
Global Climate Variation
- Arctic Oscillation
- ENSO
