Smoke filled the skies over western Canada and even much of the United States in May 2023. The source was several wildfires in Alberta and British Columbia.
Near the end of May, rain and cooler temperatures finally brought some relief for the out-of-control fires.

A winter of heavy rain causes flooding in California's Tulare Basin, threatening cropland. The basin was once the site of a large lake that appeared naturally every winter as rainfall and snowmelt from the nearby Sierra Nevada mountain range flowed down and filled the basin. It was even known as the largest lake west of the Mississippi River.

An iceberg the size of Houston broke from the Brunt Ice Shelf Antarctica on January 22nd, 2023. Landsat images show the area one day before the break and several days after. A feature named Chasm One had been lengthening for years, and it finally reached all the way across the shelf.

The HydroAdd tool is a web application built by USGS that allows collaborative addressing (or linear referencing) of diverse datasets to the NHD. HydroAdd also provides tools that allow users to migrate datasets that have been previously addressed to the NHD.

Cheyenne Bottoms is the largest inland wetland in the United States. Water normally diverts from rivers into the vast marshland. The wetland water level changes with precipitation and surface flows. For example, 2007 was a wet year. And 2013 was a dry year.

We wouldn't have seasons here on Earth if not for the planet's 23.5 degree axial tilt. Axial tilt is also known as obliquity. Earth's obliquity and its relationship with the sun give us two solstice points and two equinox points. As we orbit through each solstice and equinox, the amount and angle of daylight change.

While the best soccer players in the world show off their footwork skills, the best Earth observation satellite program in the world displays its skill at detecting change over time. Landsat images show the rapidly growing city of Doha in Qatar. It's the country's capital and the location of the 2022 men's World Cup.

Two decades of drought are contributing to low water levels in reservoirs along the Colorado River, including Lake Powell.
Lake Powell’s highest recorded water level was in 1983. In this 1984 Landsat 5 image, the lake’s elevation was 3,702 feet above sea level.

The U.S. Geological Survey (USGS) has developed a vision for the 3D National Topography Model (3DNTM), which will integrate USGS elevation and hydrography datasets to model the Nation's topography in 3D.

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.
