Several environmental agencies have started a number of alternative ways to reduce greenhouse emissions. Scientists have specified the trends in global warming since the last few decades to the human expansion of the greenhouse gases. This means the heat which affects the environment coming from the Earth to space.

Scientists from NASA’s Research Center have the plan to build an innovative instrument. This new instrument can measure water vapors and other particles in the atmosphere.

The new information will be generated from this device will measure the accuracy of the measurements which come from the satellite. Thus, improving climate and weather forecasts.  The new instrument called HALO (High Altitude Lidar Observatory). The device uses rages and light (LiDAR). It basically works by shelling a thin laser beam over the atmosphere.

The highly powerful greenhouse gas exists in the environment is water vapor. It basically plays the role of warming the air vapors from the heat which comes from the Earth.

HALO and DAWN Instruments

HALO is an integrated device enabling research scientists to measure either methane or water vapor. The space agency integrated HALO with another supported instrument named DAWN (Doppler Aerosol Wind Lidar) that measures both direction and speed.

Both HALO and DAWN help in validating data gathered by the ADM-Aeolus (Atmospheric Dynamics Mission Aeolus) LiDAR device. European Space Agency (ESA) satellite is able to measure cloud shape and wind speeds globally.

What is Water Vapour?

HALO is highly compatible to work with NASA’s systems which shape the environment. Water vapor aids to recognize the clarity, stormy or gloomy the weather is.

To understand the cloud, its size, brightness, properties, it becomes compulsory to integrate climate models.
