Mission managers for NASA's Soil Moisture Active Passive (SMAP) observatory have determined that its radar, one of the satellite's two science instruments, can no longer return data. However, the mission, which was launched in January to map global soil moisture and detect whether soils are frozen or thawed, continues to produce high-quality science measurements supporting SMAP's objectives with its radiometer instrument.   The SMAP mission is designed to help scientists understand the links between Earth's water, energy and carbon cycles and enhance our ability to monitor and...

SMAPpers,   The GLOBE/SMAP Soil Moisture Measurement Campaign is almost here! Beginning October 1, 2015 and ending April 30, 2016, we are hoping to get a wide array of GLOBE schools participating.   NASA launched an Earth observing satellite called Soil Moisture Active Passive (SMAP) on January 31, 2015 and its purpose is to measure soil moisture globally with a high level of accuracy. Ground measurements are needed however, in order to validate the satellite measurements. To do this, the SMAP team will compare GLOBE in situ soil moisture with satellite measurements...

      On August 13-14, 2015, and with generous financial support from University of North Dakota's (UNDs) Summer Programs Office, Dr. Laura Munski and I completed our first 2-day GLOBE training at UND.  We trained three fantastic local teachers who all collaborate with the Dakota Science Center, and one GLOBE scientist who is also a PhD candidate in Atmospheric Sciences at UND.  The first day was focused on Atmosphere while the second day was focused on Earth as a System and Pedosphere ....

GLOBE students measure the current values of many environmental properties, but the Precipitation Protocol measures the total amounts and the Max/Min Atmosphere and Soil Temperature protocols measure the extremes that have occurred during the previous 24 hours. At the beginning of GLOBE, the time of day for these daily measurements was chosen as within one hour of local solar noon. The thought was that the middle of the school day would be an easy time to have students go outside and take data. Today in GLOBE, the air and soil temperatures can be measured with the digital multi-day...

Mission managers at NASA's Jet Propulsion Laboratory, Pasadena, California, are assessing an anomaly with the radar instrument on NASA's Soil Moisture Active Passive (SMAP) satellite observatory. The radar is one of two science instruments on SMAP used to map global soil moisture and detect whether soils are frozen or thawed. See more HERE!

In the summer of 2014 - at the International Student Learning Expedition in New Delhi, India, the GLOBE Implementation Office along with NASA's GLOBE Program Manager established formal working groups to engage in discussions around a variety of GLOBE Research/Science, Education, Evaluation, Communications, and Technology challenges now and into the future. These groups comprise memberships from around the world with participants from science, education and technical institutions, and GLOBE Country and Regional Coordinators. I was honored and pleased to have been elected to chair...


Posted in: GLOBE Working Groups: Technology Working Group

Hello GLOBE friends! The Evaluation Working Group was formed last summer and our first meeting took place during  the GLE in New Delhi, India. The purpose of this group is to get in touch with the people who actually do GLOBE all over the world and find out how the Program works in schools, identify tools, resources and practices, build on the existing experience and provide suggestions that can help its implementation and outcomes. For this purpose, and after having  several teleconferences, we developed a set of questions that were included in the Annual Partner Survey....

The Soil Moisture Active Passive (SMAP) mission has engaged with GLOBE to obtain surface soil moisture measurements from student citizen scientists. These measurements will become part of SMAP’s calibration/validation effort. Gravimetric soil moisture measurements are the gold standard for this environmental variable, and these may be taken by almost anyone. Through GLOBE, the resulting data can be reported and archived and put to use by the SMAP Science Team. SMAP scientists have indicated that measurements from clusters of 10 sites within a 10 km radius circle are particularly...

The radar measurements made by NASA's Soil Moisture Active Passive (SMAP) observatory are sensitive to whether land surfaces are frozen or thawed. As liquid water freezes in soil, the water molecules become bound in a crystalline lattice, which changes how the incoming radar energy from SMAP interacts with Earth's surface, compared to soil containing freely oriented liquid water molecules.
