Have you ever wondered how NASA Earth observing satellites are able to ground truth their data? What about satellites that collect data over the ocean? Is it ever possible to compare actual in situ data with data that is collected using remote sensing? It just so happens that there are several NASA scientists who will be doing just that- and more- from January 24 th through February 20 th ! And, those of us who are involved in the GLOBE Program have been specially invited to participate in several aspects of this research. We are going to hear from Dr. Ivona Cetinic, the lead...

I just came across an article from NASA's Earth Observatory that was released yesterday entitled " A Dry Start to South America’s Wet Season ". The article describes the current lack of precipitation in South America, and includes the map below. In this map, we are seeing the accumulated deficit of rainfall that is both flowing onto the surface and accumulating under the ground as of this October.   This got me wondering how South America might be impacted by the La Nina conditions in the near future. I did a little research, and found this article, also from NASA's Earth...

One of NASA's scientists, Dr. Stephanie Uz, has been working closely with the GLOBE ENSO Campaign throughout its beginning. She is an oceanographer who studies the response of ocean biology to physical forcing through remotely sensed satellite data, in situ measurements, model output and statistical reconstructions using proxies. Her research focuses on variability in global ocean color or chlorophyll concentrations, the pigment in microscopic phytoplankton, and the physical mechanisms causing those changes. Dr. Uz coordinates communication for the Plankton, Aerosol, Cloud, ocean Ecosystem...

Have you ever wondered how the SMAP satellite, with an altitude of 685 km (425 miles) above the Earth, can take measurements as precise as the amount of water in the Earth's soil? The quick answer is that it requires precisely calibrated instruments, along with a technological marvel in satellite design. SMAP was designed to use a combination of two precise instruments, one with high resolution, one with high accuracy. THE INSTRUMENTS: Active (High Resolution): SMAP’s radar was designed accurately measure the echoes of very short radio frequency (RF) pulses that bounce...
