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...
