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.

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 the...
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. From...
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 helpful....
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.

Hello reader! My name is George Duffy! I am a graduate student from the University of Urbana Champaign, and I am excited to begin sharing my experience as a GPM graduate researcher of with you.
My research focuses on snow, or more specifically, snowfall retrieval. Technically, the GPM satellite doesn't measure precipitation, it measures radar echoes from its Dual Frequency Precipitation Radar (DPR) and radiation from it's General Microwave Imager (GMI). It's up to us to develop algorithms that can retrieve precipitation information from these radar images. It's also...
The term “won in a landslide” is particularly troubling to me because when a landslide happens, the kind that I study at least, there are seldom “winners”. My research looks at how rainfall interacts with the environment to cause natural disasters like flooding and landslides. Knowing where, when and how much rain or snow is falling is key to understanding where we may have extreme events that can impact people.
If you consider where we get a lot of rainfall, like some of our tropical regions…
...and combine that with areas that have the right factors to cause a landslide, such as steep...
So, now that we have a satellite in space called SMAP, why is the data from the spacecraft so important?
SMAP will help:
Assist Crop Productivity
Improve Weather Forecasting
Linking Water, Energy, and Carbon Cycles
