What are the instruments that measure the atmosphere?

Thermometers, barometers, and other in-situ instruments—instruments that enable us to directly measure the air (“ in situ ” meaning “on site” or “in place” in Latin)—are essential to exploring the immediate atmosphere. But what if scientists want to explore how the atmosphere might act hours or days into the future, or in another part of the world? For this, scientists depend on remote-sensing instruments—tools that obtain information from some distance away.

How do scientists use weather balloons?

Weather balloons ascend to lofty heights with a package, known as a radiosonde, following close behind. As the radiosonde rises, its internal sensors measure characteristics such as temperature, pressure, and relative humidity, and a radio transmitter relays this data back to scientists every one to two seconds. Scientists then use this data (along with wind speed and wind-direction data, which are calculated by tracking the radiosonde’s position) to create weather forecasts and provide input for weather models.

How high is the atmosphere?

Earth’s atmosphere is about 97 kilometers (60 miles) high, not including the exosphere—the uppermost layer that some scientists consider more space-like than atmosphere-like. While 97 kilometers may not sound far, imagine trying to observe an event, such as a baseball game, from that distance. It is virtually impossible. Similarly, the distance from Earth’s surface to the upper levels of the atmosphere prevents scientists from discerning what happens there. Scientists require instruments far more accurate and discerning than the human senses to help bridge the distance between Earth’s surface and its atmosphere; this is where technology comes into play.

How do weather models work?

Atmospheric data is fed into them so that they can “model” or simulate what the atmosphere’s conditions might be at some time in the future. The models do this by solving a group of mathematical equations (at speeds of quadrillions of calculations per second—weeks faster than can be done by hand), which govern how the atmosphere behaves in reality. In this way, the model is able to approximate what the atmosphere is likely to do before it actually does it.

What is satellite in science?

object that orbits around something else. Satellites can be natural, like moons, or artificial.

How does radar work?

Unlike weather balloons and satellites, which scan the atmosphere from above, radar works by scanning it from ground-level. By observing how pulses of energy called radio waves interact with objects they meet in the air, scientists are able to detect the location of rain, snow, and other types of precipitation. Doppler radar allows scientists to not only detect a storm’s location, but its movement too. This is important for understanding whether a storm is approaching or moving out of a specific area and whether any rotation (a sign of possible tornadoes) exists in the atmosphere.

Its electronic sensors change in proportion to the level of moisture in the air.

How does a weather balloon work?

A weather balloon or sounding is a sort of mobile weather station in that it carries instruments into the upper air in able to record observations of weather variables (like atmospheric pressure, temperature, humidity, and winds), then sends back this data during its suborbital flight. It is comprised of a 6-foot-wide helium- or hydrogen-filled latex balloon, a payload package (radiosonde) that encases the instruments, and a parachute that floats the radiosonde back to the ground so that it can be found, fixed, and reused. Weather balloons are launched at over 500 locations worldwide twice per day, usually at 00 Z and 12 Z .

How does satellite data help predict weather?

Variations in rain, snow, and other forms of precipitation are an integral part in everyday weather and long term climate trends. Initialization of short-term weather and long-term climate models with accurate precipitation information enhances their prediction skills and extends their skillful lead times. To get the resolution and temporal coverage to measure precipitation across the globe, we often rely on satellite information. Satellite data can play a fundamental role in our ability to monitor and predict weather systems as well as to forecast future changes to our climate and land surface. Satellite data from GPM’s suite of precipitation products are integrated into numerical weather prediction models that are operated by operational partners to provide and improve the observations from which the forecasts are then generated. Similarly, climate and land surface models use satellite precipitation observations from GPM to describe the conditions that exist today in order to project how conditions may change in the future. The Weather, Climate, and Land Surface Modeling applications area promotes the use of GPM data to help monitor existing weather activity and model future behavior of precipitation patterns and climate.

How does CIRiS work?

CIRiS collects infrared energy and uses a “focal plane” to convert that energy to an electrical signal , similar to how a digital camera turns visible light energy into an electrical signal. Many focal planes for infrared detection require operation at cryogenic temperatures, and therefore must incorporate a cryocooler to establish those temperatures, Osterman said. The team decided to use a different type of focal plane that operates without cryocooling to decrease the sensor’s size.

Can CIRIS be used in space?

If CIRiS is successful in proving it can operate in space, Osterman hopes to see a small constellation of CIRiS-like instruments orbiting Earth. Multiple CubeSats in orbit would allow us to measure changes in evapotranspiration and other phenomena potentially as often as every day.

Why are data adjustments required?

Data adjustments may also be required if there are changes to the time of day that observations are made. If, for example, a network of weather stations adopts a uniform observation time, as they did in the United States, stations making such a switch will see their data affected, because temperature is dependent on time of day.

How long have scientists been building estimates of the temperature of the Earth?

Scientists have been building estimates of Earth’s average global temperature for more than a century, using temperature records from weather stations. But before 1880, there just wasn’t enough data to make accurate calculations, resulting in uncertainties in these older records. Fortunately, consistent temperature estimates made by paleoclimatologists (scientists who study Earth’s past climate using environmental clues like ice cores and tree rings) provide scientists with context for understanding today’s observed warming of Earth’s climate, which has no historic parallel.
