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 24th through February 20th! And,...
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...
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...
