This should enable it to determine about 10 or 11 classes of soil moisture.
The second, known as Smos, is measuring soil moisture and ocean salinity, and was launched in November.
Local temperatures would still change in some places, as would ocean currents, rainfall patterns, soil moisture and photosynthesis.
Rising temperatures also are likely to reduce soil moisture, cutting yields even further.
The university team studied 18 rock panels and looked at the effects of factors such as soil moisture, salinity and height.
According to the Global Soil Moisture Data Bank, global soil moisture increased throughout the 20th century at almost all sites.
FORBES: The Overwhelming Judgment of Science Rejects Obama's Global Warming Claims
As I documented in my October column, African deserts are receding, soil moisture is improving and crop production is dramatically increasing.
FORBES: Despite What You Hear, Global Warming Is Still Benefiting Africa
U.S. and global soil moisture improved throughout the 20th century as our planet warmed in its recovery from the Little Ice Age.
FORBES: The Overwhelming Judgment of Science Rejects Obama's Global Warming Claims
In response, I presented powerful evidence that African deserts are actually shrinking, soil moisture is improving, and crop production is dramatically increasing.
FORBES: Despite What You Hear, Global Warming Is Still Benefiting Africa
With more moisture evaporating from the oceans and falling over the land as rain, global soil moisture has been improving for more than a century.
FORBES: Global Warmists Allergic To The Truth During Pollen Season
This is being prepared with data from every rainfall station across the country, together with readings from the UK's 1300 river gauges, plus information about soil moisture.
Bolstered by increasing soil moisture, longer growing seasons, warmer winters, and the fertilizing effects of more atmospheric carbon dioxide, crop production continues its long and impressive run of ever-increasing yields as global temperatures warm.
FORBES: Fortified By Global Warming, Crop Production Keeps Breaking Records
By measuring the way their fields reflect and emit energy at visible and infrared wavelengths, precision farmers can monitor a wide range of variables that affect their crops such as soil moisture, surface temperature, photosynthetic activity, and weed or pest infestations.
These changes are making water supply and quality more difficult to obtain, affecting runoff and soil moisture, increasing water temperatures, decreasing snowpack and lake and river ice, threatening fish and aquatic species, and allowing saltwater intrusion and sea level rise.
As a result, even though wildfires occur less frequently as our planet warms and as soil moisture improves (more on that coming right up), our global warming Alarmist in Chief presents the misleading assertion that global warming rather than a change in federal wildfire policy is causing a recent increase in acres burned due to wildfires.

Sugar beets can be grown anywhere else in the US with ample soil and moisture including Alaska.
Meteorologists say the dry conditions in the Midwest started with a lack of snow, which usually replenishes soil with moisture.
Fire ants, he explained, could build stable tunnels in sand or soil with almost no moisture to bind it together, so learning from them might enable designers to build and programme robots that solve these same engineering problems.
This means that the plant doesn't need to draw as much moisture from the soil.
They will look, too, at the amount of ice in the ground, and the temperature and the moisture of the soil.
And in some of the world's great winemaking regions, such as California, geological variations mean that the ability of soil to retain or lose moisture can change within distances of a few metres.
Working organic amendments such as compost into your soil will help it drain faster and retain a more even level of moisture.
It also carries the risk of producing an inaccurate picture of the overall distribution of moisture, as the spots chosen for sampling may be considerably damper or drier than the soil just a few metres away.
