GRACE Data Assimilation and GEOS-5 Forecasts

Complete transcript available. NASA satellites, data, missions, and programs have been put to use for decades to strengthen food security, track droughts and flooding, determine plant and soil health and otherwise support agriculture decision making. With observations from space and aircraft, combined with high-end computer modeling, NASA works with partner agencies, organizations, farmers, ranchers, and decision makers to share our understanding of the relationship between the Earth system and the environments that provide us food. Working with local communities and decision makers to determine their needs and how they can best use Earth observation data, NASA supports those who address issues like water management for irrigation, crop-type identification and land use, coastal and lake water quality monitoring, drought preparedness, and famine early warnings.

Music: "Connections Established," "Data Visions," Universal Production MusicComplete transcript available. Continuing key observations of the Earth is really important to see how our atmosphere, land and oceans are changing over time. A long term record, combined with cutting edge observations from the new NASA Earth System Observatory, will continue to push boundaries to better understand our ever changing Earth. Related pages

Music: "Solar Winds" by Ben Niblett [PRS] and Jon Cotton [PRS] courtesy of Universal Production Music.Complete transcript available. On the afternoon of June 13, 2020, a vehicle fire near the intersection of Bush Highway and State Route 87 ignited the brush and grass nearby. As of June 25, 2020, the Bush Fire is one of the five largest fires in Arizona's history. NASA’s satellite instruments are often the first to detect wildfires burning in remote regions, and the locations of new fires are sent directly to land managers worldwide within hours of the satellite overpass. Together, NASA instruments detect actively burning fires, track the transport of smoke from fires, provide information for fire management, and map the extent of changes to ecosystems, based on the extent and severity of burn scars. NASA has a fleet of Earth-observing instruments, many of which contribute to our understanding of fire in the Earth system.

Music: Lines of Enquiry by Theo Golding [PRS]Complete transcript available. Using measurements from two satellite missions assimilated into a computer model, researchers have created global maps of terrestrial water around the planet. In addition, they can forecast water availability in the United States up to three months out. Related pages

This data visualization of black carbon from the GEOS forward processinf (GEOS-FP) model shows the abundande and direction of black carbon from New South Wales (NSW) and Queensland blowing through the atmosphere from November 1-18. The summer of 2020 was marked by extremefires in Siberia and the Western United States. Series of extensive and powerful wildfires charred vast swaths of forest and shrubland and altered the composition of the atmosphere in the Northern Hemisphere. We study Earth and how it’s changing from the ground, the sky, and space. Using data from sensors all around the planet, we calculate the global average temperature, working with our partners at NOAA.

NASA Earth Observatory images by Joshua Stevens, based on data from the NASA Goddard Institute for Space Studies/Gavin Schmidt NASA Earth Observatory images by Joshua Stevens, based on data from the NASA Goddard Institute for Space Studies/Gavin Schmidt NASA Earth Observatory images by Joshua Stevens, based on data from the NASA Goddard Institute for Space Studies/Gavin Schmidt National Interagency Fire Center image of Loyalton Fire in August 2020 Globally, 2020 was the hottest year on record, effectively tying 2016, the previous record. Overall, Earth’s average temperature has risen more than 2 degrees Fahrenheit since the 1880s. Temperatures are increasing due to human activities, specifically emissions of greenhouse gases, like carbon dioxide and methane. Related pages
