NASA discovers by accident a way to improve weather forecast

NASA discovers by accident a way to improve weather forecast

Occasionally, we see the weather forecast and we went out with an umbrella, to meet a bright sunny day. Or maybe the other way around: We left without an umbrella and got wet. The weather forecast still has room for improvement, and may have found something to do.

Researchers working on a way to protect the places where the remains of the Apollo missions to the by accident found a system that could be applied on Earth. While working in the garden during rainy days, the physicist John Lane found that the laser and the reflector was developed to track lunar dust could also accurately determine the size of the water droplets, which estimates current weather systems , but not blood.

The quantity measured by the laser is called “second stage size distribution”, which is the average of drops passing through a zone of the laser. According to Lane, this information may be useful to complete the complex calculations that are made now to identify and predict weather.

“We could refine computer models to make them more accurate. Analysis of weather radars make assumptions about the size of the drops, so I think this could improve the overall estimates of droplet distribution, “said Lane.

Originally, Lane worked with fellow physicist Phil Metzger in a way to calibrate the laser sensor to record dust rising from the soil of the Moon. The investigation seeks to determine how close to the six Apollo sites can park a new robot in the natural satellite, without damaging the materials were there. Dust rises could damage the metal of the lunar modules, which were left on the moon between 1969 and 1972.

“Apollo sites have scientific value, and engineering perspective because they have seen how these materials on the Moon have interacted with the solar system in the past 40 years. They witness the environment, “says Metzger. There are also bags of trash left by the astronauts up there, and that biologists want to analyze to see what happened to living organisms that were in the waste.

The plan is to install a NASA laser sensor (in which they work and Metzger Lane) in the bottom of one of the robots participating in the contest Google Lunar X-Prize , which aims to send a small robot to the moon in 2014.
