Atmospheric Sciences

Atmospheric science is the study of the atmosphere, its processes, and the interaction of the atmosphere with other systems, including the effects other systems have on the atmosphere and visa versa. Fields in Atmospheric Sciences include Meteorology, Climatology, and Aeronomy. Ask and answer questions about Atmospheric Sciences in this category.

What things are found in the ionosphere?

The ionosphere contains charged particles such as ions and free electrons. It also includes layers of the atmosphere where ionization occurs, leading to phenomena like auroras and radio wave propagation. Additionally, the ionosphere plays a crucial role in reflecting radio signals back to Earth.

What is the outer layer of the thermospherer?

The outer layer of the thermosphere is called the exosphere. It is the outermost layer of Earth's atmosphere and extends beyond the thermosphere. The exosphere is where gas particles are extremely sparse and can travel long distances without colliding with each other.

How much does an astronomer make a month?

Salaries for astronomers can vary depending on experience, education, and location. On average, astronomers in the United States earn between $5,000 to $8,000 per month. However, this can vary significantly based on the specific employer and level of expertise.

What happens in the trmperature in the atmosphere as you go up through the troposphere?

The temperature typically decreases as you go up through the troposphere. This decrease in temperature with altitude is known as the lapse rate, and is usually around 6.5°C per kilometer of altitude.

How does the gravity at the altitude the space shuttle flies compare with the gravity on earth?

if you know earth surface radius and acceleration due to gravity, you can use the following equation to find acceleration at another radius (say geostationary orbit where the communication satellite's are)

.

a = k / ((d/r)^2)

.

where:

a = required acceleration at goestationary orbit ( ? (m/s)/s)

k = earth surface acceleration due to gravity (9.81 (m/s)/s)

d = geo stationary orbital radius (42 170 000 metres)

r = earth surface radius ( 6 371 000 metres)

.

so acceleration at geostationary orbit = 0.224 (m/s)/s

compared to acceleration on earth = 9.81 (m/s)/s

.

say shuttle = 25 000 kg

(weight on earth) f= m*a = 25 000 * 9.81 = 245 250 newtons

(weight at orbit ) f=m*a = 25 000 * 0.224 = 5 600 newtons

note: the force on the shuttle in orbit is balanced by the centripetal force created by its motion in a circle, its required velocity can be calculated from:

v = sq.root(a * d)

v= 3073 m/s

Why is the colour of sky blue at night?

at night the sky is usually red due to the less amounts of sunlight the sky is blue in the day because of a process called scattering where the visible spectrum is reflected of of particles called aerosols. this was written by a sixth grader if you dont understand then too bad

Are there shadows made by the sun even at night?

Yes, when it's night here, the sun is shining and making shadows on the other side of the world.

What is the main use of aneroid barometer?

An aneroid barometer is mainly used to measure atmospheric pressure. It can be used to predict weather changes by tracking fluctuations in pressure. This can be particularly useful for activities such as weather forecasting, aviation, and hiking.

Is there less oxygen today than 1000 years ago?

The atmosphere has the same amount of oxygen today as it did 1000 years ago. Although oxygen gets used up in various ways, through fire and through metabolism, oxygen is constantly being released into the atmosphere by green plants.

Which type of waves is not reflected by the ionosphere?

Microwaves are not reflected by the ionosphere because their wavelengths are too short for the ionosphere to effectively reflect them. This is why microwaves are commonly used for satellite communication, as they can pass through the ionosphere to reach satellites in space.

Which is the thickest layer of atmosphere and where is it located?

The thickest layer of the atmosphere is the troposphere, which is located closest to the Earth's surface. It extends up to about 10-15 kilometers above sea level and contains the majority of the Earth's atmospheric gases.

What are extraterrestrial particles that glow brightly and burn up as they travel through Earth's atmosphere?

Those are most likely meteors, which are space debris that enter Earth's atmosphere at high speeds. The friction from the atmosphere heats up the meteor, causing it to glow brightly and eventually burn up, creating a streak of light known as a meteor or shooting star.

Does a comet burn when it enters the earth atmosphere?

Yes, a comet experiences intense heating and friction as it enters Earth's atmosphere, causing it to burn and create a bright streak of light known as a meteor or shooting star. This process is due to the extreme speed at which the comet is traveling through the atmosphere.

What layer of atmosphere do helicopters fly in?

Helicopters Can fly in the thermosphere and sometimes into space. I am a professor at Cambridge university and i am an expert in helicopter space flights.Call me at 320-567-5667

^Whoever fking wrote this, I'm laughing so hard rn

When small pieces of rock moving through space enter earths atmosphere and burn up they're called?

When small pieces of rock moving through space enter Earth's atmosphere and burn up, they are called meteoroids.

Does the density of the earth's atmosphere increase with altitude?

The atmosphere becomes less dense with altitude. Atmosphere, thin though it is, has weight, and it is the weight of the air above which compresses the air below it, to greater density.

What orbit high above earth and use instruments to gather data from the upper atmosphere?

Satellites in geostationary orbits are positioned high above Earth and equipped with instruments to collect data from the upper atmosphere. These satellites remain fixed over a specific point on Earth's surface, continuously monitoring weather patterns, atmospheric conditions, and other phenomena.

What is the approximate temperature of stratosphere?

The temperature of the stratosphere can vary depending on the altitude, but on average it ranges from about -60°C to 0°C. The stratosphere is located above the troposphere and contains the ozone layer, which plays a key role in absorbing and scattering the sun's ultraviolet radiation.

Is it true that the earth has changed very little over time?

No, the Earth has changed significantly over time through geological processes such as plate tectonics, erosion, and volcanic activity. These processes have shaped the planet's surface, creating mountains, oceans, and other geological features we see today.

What is the three types of layers in the sky?

The three main types of layers in the Earth's atmosphere are the troposphere (closest to the surface and where weather occurs), the stratosphere (contains the ozone layer that absorbs UV radiation), and the mesosphere (where most meteors burn up).

What is Triton's atmosphere made up of in percents?

Triton's atmosphere is made up of about 70% Nitrogen, (N2) 20% Methane (CH4) and roughly 10% Carbon Monoxide (CO).

What is the atmosphere mainly made up of?

The Earth's atmosphere is mainly composed of nitrogen (about 78%) and oxygen (about 21%). Other gases present include argon, carbon dioxide, and traces of other gases like helium and methane. Water vapor is also an important component of the atmosphere.

Is the exosphere 80-550 kilometers above sea level?

Yes, the exosphere is typically located between 500-1000 kilometers above sea level, although it varies depending on solar activity and other factors. It is the outermost layer of Earth's atmosphere and contains very low densities of gas molecules.

Did outer planets lose the light gases in their atmosphere?

Yes, outer planets like Jupiter and Saturn likely lost light gases from their atmospheres due to their gravity not being strong enough to retain these gases. Additionally, the strong solar wind and radiation in the outer solar system may have contributed to the loss of these gases over time.
