Lake Mead and the Mega Drought.
Image of the Week.
Drought over the past 20 years in the Colorado River Basin, and a growing demand for water, have brought Lake Mead to historically low levels.
In 1972, the year Landsat 1 captured its first images, Lake Mead’s elevation was 1,155 above sea level.

When disaster strikes, near-real-time images of its effects can be invaluable. In this episode of Eyes on Earth, we learn about how a newly developed system using the Harmonized Landsat Sentinel-2 dataset and artificial intelligence was put to the test when Hurricane Ian tore through Florida in late September 2022.

ECOSTRESS, or ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station, data provides variables related to plant water stress, including evapotranspiration, evaporative stress index and water use efficiency. The NASA Land Processes Distributed Active Archive Center (LP DAAC) at EROS provides storage and distribution of ECOSTRESS data.

The Global Ecosystem Dynamics Investigation, or GEDI, instrument on the International Space Station acquires lidar waveforms to observe the Earth’s surface in 3D. The GEDI lidar measures the height and density of objects, so it provides information such as surface elevation and tree canopy height and cover.

HVO volcanic gas specialists make sulfur dioxide (SO~2~) emission rate measurements downwind of the eruption within Halema‘uma‘u crater, Kīlauea summit. This video shows the typical fieldwork involved with measuring SO2 emission rates, during which HVO scientists drive traverses beneath the plume in the closed area of Hawai‘i Volcanoes National Park.

The Landsat satellites have been collecting Earth imagery for more than 50 years. A key piece of equipment that moves the data from the spacecraft to the archive so researchers can use it is the antenna at the EROS Center. The antenna and its radome have a fascinating history of their own that adds to the overall Landsat story.
