HLS: Visualizing Stromboli's Eruptions

Harmonized Landsat and Sentinel-2 (HLS) data are here!

The LP DAAC and the HLS Science Team are pleased to announce the release of Harmonized Landsat and Sentinel-2 (HLS) version 2.0 surface reflectance products. HLS data are composed of observations from Landsat 8 and Sentinel-2 and provide a set of seamless data products that can be utilized as if all observations

Image of the Week - Dixie Fire Ravages Northern California

The Dixie Fire has become the largest single fire in California's recorded history. State fire officials don't list it at the top, however. The record is held by the massive August Complex fire of 2020 which burned over one million acres. The term "complex" is used when multiple fires in the same area ignite separately. Designating the fires as a complex allows them to be

Earth As Art 3

The Earth As Art project began in the early 2000s, and its original intent remains the same: to produce images that do not look like satellite images at first glance. Earth As Art shows not only what satellites capture in the visible wavelengths of light you and I can see, but also what’s hiding in the invisible wavelengths that Landsat sensors can detect in the infrared

Image of the Week - Dry Spell Depletes Northern California Reservoirs

A prolonged dry spell has sparked woes over water availability and wildfire in the western United States.

This stretch of northern California is heavily reliant on man-made reservoirs. The recent history of a single Landsat scene can serve to illustrate the ripple effects of those severely parched conditions. Water levels have dropped in Folsom Lake, Indian Valley

What is GEDI?

Meet GEDI! The Global Ecosystem Dynamics Investigation sensor aboard the ISS!

The Global Ecosystem Dynamics Investigation (GEDI) is a full-waveform lidar instrument that produces detailed observations of the 3-dimensional structure of the Earth’s surface. GEDI precisely measures forest canopy height, canopy vertical structure, and surface elevation which enhances

Eyes on Earth Episode 57 – Landsat and the Great Lakes

The Great Lakes represent roughly 20% of the surface freshwater in the world and 90% in the United States. The Great Lakes Basin supports more than 30 million people in the U.S. and Canada and 3,500 plant and animal species. The region faces threats that range from climate change and invasive species to pollution and development. Identifying and addressing those threats

Image of the Week - Cold War Craters in Nevada

One of the most cratered landscapes on Earth is part of the Nevada Desert called Yucca Flat. Landsat 8's near-infrared and short wave infrared imaging shows the pockmarked surface perhaps more reminiscent of other planetary bodies than Earth.

The craters are relics from decades of nuclear tests conducted by the U.S. government since the early Cold War. An aerial

Eyes on Earth Episode 55 - Urban Heat Islands of New York

Urban heat islands occur in areas containing more impervious surfaces and fewer natural environments. The day and night surface temperature is higher in urban heat islands than in surrounding areas. During heat waves, this can lead to greater numbers of heat-related illnesses and deaths. Landsat satellites collect data on surface temperature and vegetative change that can
