Soil moisture might not be considered a critical factor to the health of our planet but a series of satellite missions are proving otherwise. Scientists recently created maps from NASA’s Aquarius satellite of soil moisture, or the amount of water contained within soil particles, across the globe. These maps have […]
Water is essential for life on the Earth, and the supply of this precious liquid is constantly being recycled through energy from the sun. This process is known as the hydrologic cycle, and through it water is continuously exchanged between the land, the atmosphere, and the oceans. Precipitation in its […]
Forty years representing over a dozen of Earth observation missions by NASA has led to an invaluable archive of satellite imagery and remote sensing data. These mission have gathered data about the Earth including its atmosphere, vegetation, ice, land surface, salinity levels, geology, and temperature. The highlight the datasets developed by […]
NASA Earth Observations (NEO) has overhauled the look of its web site: “NASA Earth Observations (NEO), has a new look and we invite you to try it out! Over 50 different global datasets are represented with daily, weekly, and monthly snapshots, and images are available in a variety of formats […]
