A new device that can measure power in the atmosphere, says it can provide weather forecasts for the UK for the first time, but some experts warn it may be too accurate.
The new Power Meters, which can measure wind speed, temperature, humidity and CO2 levels, were unveiled at a meeting of the National Academy of Engineering (NAE) in Birmingham, UK.
“There’s been a lot of work on weather forecasts, but they’re mostly based on observations, which are difficult to validate,” says Dr Mark Aiken, lead author of the study.
What is an atmospheric CO2 sensor?
The UK’s National Weather Service (NWS) is using a pair of power meters to monitor the temperature of the atmosphere for CO2 measurements.
Aiken says the sensors are very sensitive and can measure up to 4 times higher CO2 than a traditional wind-meter.
He says they’re not sensitive enough to detect CO2 that’s in the air at any given moment.
However, they can detect CO3 in the form of CO2 and methane that’s trapped in the ground, so it’s likely to be higher than what is measured in the wind.
So how accurate are the Power Metres?
“The sensors are quite sensitive to CO2 concentrations.
They have a sensitivity of up to 30 ppm, and it’s about twice as sensitive to methane concentrations as to CO 2 ,” he says.
According to the National Atmospheric Research Organisation (NARO), “the power meter can detect atmospheric CO 2 levels of up a factor of five.
This is because of the fact that it detects the temperature and humidity of the air in a small area of space, rather than measuring it in a large area.
NAROs centre of excellence in atmospheric CO concentration measurements, NARO is based at the University of East Anglia in the UK, and it uses the same instruments as the National Weather Servers.
Using a Power Meter to Measure Wind Speed, Temperature, Humidity and CO 2 is the first of its kind, says the National Academy.
And it’s the first to measure the atmospheric CO content, says the National Academy of Science In the US, the US National Weather Center is using wind meters to measure CO2 in the stratosphere, but the sensor in the US does not measure CO 2 directly.
But in the NCEE meeting, Dr Mark Aickson says a new sensor developed by the University of Oxford has been developed that can do this.
It does all the measurements in a very small area, but the sensors measure the CO2 concentration.” “
It’s basically a wind-metric device,” he says.
“It does all the measurements in a very small area, but the sensors measure the CO2 concentration.”
So it can be used to monitor temperature and CO concentration in the troposphere, but it also has a broader use for climate forecasts.
Are there other sensors available?
There are many sensors available that measure the atmosphere and can provide information on CO2, so a sensor that’s designed for weather forecasts can be useful.
One of the first is the NASA Advanced Sensing Instrument (AISI), which is a prototype of an atmospheric sensor.
Dr Aiken says that AISIs can measure the pressure and temperature in a fairly narrow area of the tropics.
There’s a prototype at the University, but a US$1.5 million (NZ$1m) contract has been awarded to the European Space Agency (ESA) to develop a sensor with a broader range of capabilities.
That’s the Sensor-2A, a sensor designed to measure wind speeds and humidity.
An aerospheric sensor called the CloudSat-2, is based on an atmospheric device that has a range of features, including cloud-to-ground and atmospheric-to -air communication, which means it can send data to a ground station and measure temperature, CO2 or humidity.
“These are very simple sensors that are useful for climate models,” AIKEN says.
They have a range of capabilities, he adds, such as weather forecasts.
What does this mean for you?
A metric is an electrical measurement that measures electrical signals.
When an electrical signal is measured, it can give a value.
In a wind meter, for example, you measure wind power, a measure of how much wind is moving in a given direction, which is then converted to a measurement of speed.
In an atmospheric measure, for example, atmospheric CO levels can be measured by the sensor, which can measure temperature, CO and CO3 concentrations.
If the wind speed and the humidity are both high, then the
