Runoff | NASA Earthdata Runoff is the measurement of the flow of water into a lake, stream or other waterbody, usually expressed in cubic feet per second The flow is produced by rainfall from storms, precipitation accumulation or transpiration, melting ice or snow, seepage, evaporation, and percolation Determining the runoff potential of an area is important data for water resources and agricultural management
Essential Variables - NASA Earthdata Essential Climate Variables as defined by the Global Climate Observing System; there are 54 focused on the atmosphere, cryosphere, ocean, anthroposphere, biosphere, and the hydrosphere
Water Temperature | NASA Earthdata Water temperature is an essential parameter in evaluating the composition and biological activity in a water body The temperature of lakes, rivers, and oceans affects the health of plants and animals that live in and around these bodies of water Increased water heat can contribute to the decline and migration of fish populations, the bleaching of coral, and an increase in toxic algae blooms
Biogeochemical Cycles | NASA Earthdata In particular, biogeochemistry examines the factors that influence cycles of key elements such as carbon, nitrogen, and phosphorous and the impacts of the elements as they flow through the reservoirs in the Earth system—the atmosphere, hydrosphere (water and ice), biosphere (life), and lithosphere (rock)
Aqua | NASA Earthdata More than two decades after launch, NASA's Aqua satellite is providing essential data about Earth's water cycle, from clouds to soil moisture to sea ice
Ground Water | NASA Earthdata NASA's ground water datasets provide important details on the amounts, locations, movement, and use of water around the world
