Ένα ενδιαφέρον άρθρο για το πώς η NASA μπορεί να βοηθήσει στη μέτρηση της υγρασία του εδάφους με τη χρήση δορυφόρων!!!

Ακολουθεί το άρθρο γραμμένο στα Αγγλικά. Η πηγή είναι απο το site https://share.america.gov/ και το άρθρο με τίτλο NASA satellite collects soil moisture data


Help for farmers?from outer space

If you wanted to find out how water is distributed in soil, what would you do?  Dig a hole?

No, you would go up in the sky to get a better view. At least that was NASA?s answer.

In January, the U.S. space agency launched the Soil Moisture Active Passive satellite, designed to collect data on soil moisture around the globe. The orbital observatory uses microwave radar and radiometer instruments to ?see? through clouds and vegetation and peer into the top five centimeters of soil to measure its water content, both liquid and frozen. The goal is to better understand Earth?s three fundamental systems: its water, energy and carbon cycles.

Experts expect the satellite to produce the highest-resolution, most accurate soil moisture maps ever obtained. Combined with data from other space missions, they will reveal ?deeper insights? into how Earth?s water cycle ? the storage and flow of water in the environment ? is evolving globally and regionally in response to climate change, said Dara Entekhabi, who heads the project?s science team at the Massachusetts Institute of Technology. This information will help improve global climate change projections.

Farmers worldwide can benefit from the three-year mission because the satellite data will allow them to better manage crops. Governments and international organizations can use the data to forecast floods and droughts more accurately and to improve famine early-warning systems.

The first soil moisture map produced in April showed dry conditions in the southwestern United States and in Australia?s interior, as well as moist conditions in the U.S. Midwest and in eastern regions of the United States, Europe and Asia.
