Landsat Updates are prepared periodically and distributed electronically to provide information about Landsat activities and related topics of interest. Read this issue here.

Examples of different radiometric resolutions over Chicago, Illinois. The left image is 16-bit radiometric resolution (65,536 discrete shades of grey), the center image is an 8-bit radiometric resolution (256 discrete shades of grey), the right image is 4-bit radiometric resolution (16 discrete shades of grey).

This Landsat 9 image, showing the Dallas - Fort Worth area of Texas, was acquired on July 15, 2022. This false-color image vegetated land in shades of red, whereas grays and whites indicate urban or rocky surfaces.

Two Earth-observing satellites turned to watch a lunar eclipse, revealing dramatic and uneven temperature changes across our closest celestial neighbor.

Over the course of the four-hour eclipse, the TIRS sensors observed the intensity of infrared light radiating from the Moon’s surface. From those radiances, scientists calculated the temperatures required to generate them. This “brightness temperature” of the lunar surface changed as Earth’s shadow marched across the lunar landscape.

Using Google Earth Engine and Landsat, this team created a rapid and robust tool for mapping historical flood inundation areas. This enhances existing efforts towards flood mitigation, monitoring, and management.

Landsat 9 launched into space on September 27th, 2021. The "first light" images arrived on October 31st. On that day the satellite captured: algal blooms in Lake Erie, the glaciers of the Himalayas, bush fires in Australia's Eucalypt Woodlands, coastal communities on the Florida panhandle, and deserts, mountains and mesas across the Navajo Nation.

Multiple items appear along the various rivers including leaky weirs, one rock dams, log dams, gabions, check dams, trincheras, and earthen berms. Informational bubbles appear alongside these various item in the illustration.

An optimal opportunity for in-flight cross-calibration occurred when Landsat 9 flew underneath Landsat 8 while moving into its final orbit. Since the two satellites nearly identical imaging systems, the underfly event offered ideal cross-calibration conditions.

A map showing all the finished points as of May 2, 2022. These points do not need to be checked again at this time. They have a blue, purple, or yellow border in the editor.

A map showing volunteer contributions from the inception of TNMCorps through March 31, 2022. Contributions are displayed by fiscal year with contributions during the current fiscal year displayed by quarter. Points are color-coded on a graduated gray-to-red scale; older points are gray and newer points are red.
