The article presents a research study that answers the questions related to the color of the sky. To identify the color of the sky, the research explores the earth's atmosphere and the effects of light. The author stresses that the earth's atmosphere is protected by blankets of gases and water, where the common combination includes nitrogen, oxygen, and water molecules. The sky will become black when there is no air to scatter the sunlight. Different color of the light corresponds to the different wavelength that are part of the spectrum ranges from the long wavelength. Furthermore, when the sun is near the horizon, the color of the sky will appear orange or red due to light traveling through more atmosphere.

    The wind extraction due to assimilation of stratospheric trace gas (tracer) data is examined using a 4DVar (four-dimensional variational) data assimilation system based on the shallow water equations coupled to the tracer continuity equation. The procedure is outlined as follows. First, a nature...
