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...

Guest Blog by NASA SMAP Scientists Dr. Erika Podest and Dr. Narendra Das of the NASA Jet Propulsion Laboratory in Pasadena, California USA. SMAP scientists are using soil moisture in a number of ways, ways that allow all of us to better understand water’s role on Earth: Weather Prediction : Water in the soil has the potential to evaporate (depending on atmospheric temperature and pressure) and when it does it plays a large role in cloud formation. Soil moisture also has a modulating effect on air temperature and humidity therefore having the ability to measure soil moisture...

This week’s blog post comes to us from Dr. Janis Steele and Dr. Brooks McCutchen. Drs. Steele and McCutchen, along with their three sons, have been aboard Research Vessel Llyr since April 24, 2013. Read about their adventure in the Intertropical Convergence Zone here . When people think of life in the seas, it is often the majestic that comes to mind, such aswhales, sharks, rays and coral reefs, or our own sustenance in the form of the fish that feed billions of us around the world.  Rarely do we think of plankton, the tiny organisms found across the world's oceans. Plankton are...
