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...

Citizen science is scientific research conducted by amateur or nonprofessional scientists. Formally, citizen science has been defined as "the systematic collection and analysis of data; development of technology; testing of hypotheses; and the dissemination of the resulting information by researchers on a primarily avocational basis. When students do science, it is citizen science. This is true when students take measurements and report their data or analyze data taken by themselves and others. It is particularly true when they complete research projects by reaching evidence-base...

In the early 1980’s, I chaired a group of scientists exploring the idea of a comprehensive satellite mission to study all aspects of the global environment. The group was diverse with expertise covering the range of Earth science disciplines from geology, ecology, oceanography, limnology, glaciology, and atmospheric science and their various sub-disciplines.  Their first recommendation was take today’s data today. In all of Earth science there is the recognition that we have only one Earth to study. How Earth works is revealed by watching it change in a comprehensive manner and...

Blog originally posted on the GLOBE Scientists' Blog:  http://blog.globe.gov/sciblog/2012/11/20/globe-and-adaptation-to-climate-change/ One of the most significant technology improvements in modern life is our ability to accurately forecast future events. Weather forecasts now routinely extend for five days. The recent flooding on the East Coast of the United States was forecast days in advance. The cause was an unusual merger of two storms to create a super storm – Super Storm Sandy. Atmospheric models correctly predicted that a winter storm coming from the north and a...

This week we have a guest blogger, Dr. Dixon Butler. Dr. Butler was the GLOBE Chief Scientist from 1996-2003 and now works as a consultant to NASA. Students working on GLOBE Hydrology Protocols The general explanation of the scientific method focuses on comparing two situations that differ in only one clearly defined way. One case serves as the control while the other is the experiment. The results must be replicable as a check that the measurements were made correctly and that any other differences between the control and experiment are insignificant. This is an ideal,...
