What is the normal temperature of atmosphere?

What is the normal temperature of atmosphere?

NIST uses a temperature of 20 °C (293.15 K, 68 °F) and an absolute pressure of 1 atm (14.696 psi, 101.325 kPa). This standard is also called normal temperature and pressure (abbreviated as NTP).

What is the temperature profile of the atmosphere?

A temperature profile is how temperature of something changes as a function of distance. In atmospheric sciences, the temperature profile of the atmosphere is how the temperature of the atmosphere changes as a function of altitude above sea level.

What are the temperatures of the atmosphere layers?

Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air.

What is the average temperature on Earth?

GISS data show global average temperatures in 2017 rose 1.62 degrees Fahrenheit (0.9 degrees Celsius) above the 1951-1980 mean. According to GISS, the global mean surface air temperature for that period was estimated to be 57 F (14 C). That would put the planet’s average surface temperature in 2017 at 58.62 F (14.9 C).

What is the coldest temperature in the atmosphere?

The coldest temperatures in Earth’s atmosphere, about -90° C (-130° F), are found near the top of this layer. The air in the mesosphere is far too thin to breathe (the air pressure at the bottom of the layer is well below 1% of the pressure at sea level and continues dropping as you go higher).

What is the temperature in the upper atmosphere?

The exact temperature of the thermosphere can vary substantially, but the average temperature above 180 miles (300 km) is about 800 degrees Fahrenheit (427 degrees Celsius) at solar minimum and 1,700 degrees Fahrenheit (927 degrees Celsius) at solar maximum.

What’s the perfect temperature?

Energy.gov recommends 68 F as the optimal temperature for your home in winter for comfort and energy savings.

Why does the average temperature of the atmosphere rise?

The atmosphere today contains more greenhouse gas molecules, so more of the infrared energy emitted by the surface ends up being absorbed by the atmosphere. Since some of the extra energy from a warmer atmosphere radiates back down to the surface, Earth’s surface temperature rises.

What’s the hottest temperature on Earth?

136.4 degrees Fahrenheit
Official world record remains 134°F at Furnace Creek in 1913 In 2013, WMO officially decertified the official all-time hottest temperature in world history, a 136.4 degrees Fahrenheit (58.0°C) reading from Al Azizia, Libya, in 1923. (Burt was a member of the WMO team that made the determination.)
