If sensors are supposed to communicate with each other to compare the measured data and to secure them, then, in the future, a network of distributed sensor nodes will aid in that: the network ensures a problem-free communication between the sensors. For example, they can be used to reliably monitor the watering of plants. At the ℠embedded world´ trade fair, taking place from 2/28 - 3/1 in Nuremberg (Germany), the researchers are showcasing a technological demonstration (Hall 5,...

Grace Mission Helps Monitor Drought In the US

The record-breaking drought in Texas that has fueled wildfires, decimated crops and forced cattle sales has also reduced groundwater levels in much of the state to the lowest levels in more than 60 years, according to new national maps produced by NASA using data from the NASA/German Aerospace Center Gravity Recovery and Climate Experiment (Grace) mission. The map are distributed by the National Drought Mitigation Center at the University of Nebraska-Lincoln. The latest groundwater map,...

Members of the driving force behind ESA's SMOS mission have been awarded the prestigious Certificate of Recognition by the IEEE Geoscience and Remote Sensing Society for their leadership in developing the first synthetic aperture microwave radiometer in space and for the success of the mission. The Geoscience and Remote Sensing Society awards certificates of this kind only every two to three years, and only when a significant achievement is recognized by the society's Administrative...

Drought in Somalia, Kenya, Ethiopia and Djibouti is pushing tens of thousands of people from their homes as millions face food insecurity in a crisis visible from space. ESA's SMOS satellite shows that the region's soil is too dry to grow crops. Somalis, who already face war in their country, have been fleeing to neighboring countries in search of refuge. In Kenya's Dadaab refugee camp, for example, over 1000 people "“ mostly children "“ arrive daily, severely dehydrated and...

Western Europe's exceptionally dry spring is clear to see in maps generated using data from SMOS. While these maps offer an interesting view of the stark difference in soil moisture compared to a year ago, the data are also important for agricultural and hydrological applications. ESA's Soil Moisture and Ocean Salinity (SMOS) mission has been orbiting Earth for 18 months now, making global observations of the moisture held in the top layers of soil and salt in the surface waters of the...

Helping understand ecosystem changes and improving restoration with soil data Rising sea levels and coastal development are threatening coastal freshwater wetlands with saltwater intrusion. While most ecosystem restoration projects have focused on surface water and groundwater, new research finds that conditions in the vadose zone, the unsaturated soil below the surface but above the water table, are of particular importance to seedling survival in coastal floodplain ecosystems. ...

A simple and inexpensive demonstration of soil water retention and field capacity Using little more than PVC rings, a trashcan, and a scale, students can literally get a feel for soil water retention and field capacity, concepts that are important and useful in fields from farming to engineering. The demonstration, developed by Adam Howard, Drs. Josh Heitman and Dan Bowman of North Carolina State University, was designed to illustrate concepts that can be difficult for students to visualize...

As ESA's SMOS mission nears the end of its commissioning, a new network will provide harmonized global datasets of soil moisture measurements collected from the ground, ensuring the data received from space are as accurate as possible. Making sure data delivered from space are accurate is a crucial aspect of any Earth observation mission. One way of achieving this is to take in situ measurements on the ground and compare them with the data being acquired by the satellite orbiting above....

Despite continued interference issues, Europe's SMOS satellite is transmitting valuable new data on the way water is cycled across the globe. The satellite was launched in November to track changes in the wetness of soils and the salinity of the oceans using a microwave antenna. The detailed maps will soon be released for the eyes of the scientific community. But there are still some issues as SMOS is blinded by radar networks and media links in some areas of the world. The radio frequency...
