Inside Hurricane Maria, a 3-D perspective

This 3-D view inside Hurricane Maria, from NASA’s Scientific Visualization Studio and NASA’s Goddard Space Flight Center, lets you see the data and the lead-up to the storm in a neat 360-degree view. Be sure to watch it on your phone or with a VR thingy for full effect. Disregard the questionable color scale. Tags: 3-d, hurricane, NASA, VR

World map shows aerosol billowing in the wind

Using a mathematical model based on satellite data, NASA shows an estimate of aerosol in the atmosphere on August 23, 2018: The visualization above highlights GEOS FP model output for aerosols on August 23, 2018. On that day, huge plumes of smoke drifted over North America and Africa, three different tropical cyclones churned in the Pacific Ocean, and large clouds of dust blew over deserts in Africa and Asia. The...

A transforming river seen from above

The Padma River in Bangladesh is constantly shifting its 75-mile path. Joshua Stevens for the NASA Earth Observatory shows what the shifting looked like through satellite imagery, over a 30-year span. Kasha Patel: The upper section of the Padma—the Harirampur region— has experienced the most erosion and shows the most notable changes. The river has become wider at this section by eroding along both banks, although most activity occurred on...

Maps show spring arriving earlier

From Joshua Stevens at the NASA Earth Observatory: But over the longer term, climate change is causing spring to begin earlier and earlier across the United States. These maps reveal just how much earlier spring is arriving in National Parks across the country. The data were published in 2016 by ecologists from the National Park Service, working in collaboration with colleagues at other agencies and institutions. Griddy. Limited to only...

The Moon in 4k resolution

Based on data gathered by the Lunar Reconnaissance Orbiter, NASA pieced together this high-resolution tour of the moon. At the two-minute mark they zoom in on a boulder in the middle of a 100-million-year-old crater, and it blew my mind. Tags: high resolution, moon, NASA, space

World population estimator and gridded data from NASA

Population data typically comes in the context of boundaries. City data. County data. Country data. With their Population Estimate Service, NASA provides data at higher granularity. You can request estimated population in the context of a world grid. Here’s an interactive map to demonstrate the API. Click and drag a shape across any region in the world and get an estimate of the population within that shape. [via kottke] Tags:...

Simulation shows swirling of smoke, sea salt, and dust around the world

NASA. Data. Good. Tracking the aerosols carried on the winds let scientists see the currents in our atmosphere. This visualization follows sea salt, dust, and smoke from July 31 to November 1, 2017, to reveal how these particles are transported across the map. The first thing that is noticeable is how far the particles can travel. Smoke from fires in the Pacific Northwest gets caught in a weather pattern and...

Thermal structure of Hurricane Maria

Hurricane Maria touched down in Puerto Rico. This visualization by Joshua Stevens at NASA shows what the thermal structure of the storm looked like, based on data collected by the Terra satellite. Colder clouds, which are generally higher in the atmosphere, are shown with white. Somewhat warmer, lower clouds appear purple. The image reveals a very well-defined eye surrounded by high clouds on all sides—an indication that the storm was...

Detailed satellite view of iceberg break

Using the thermal signature, NASA provides a detailed view of the break: The false-color image was captured by Landsat’s Thermal Infrared Sensor (TIRS). It shows the relative warmth or coolness of the landscape. Orange indicates where the surface is the warmest, most notably the mélange between the new berg and the ice shelf. Light blues and whites are the coldest areas, including the ice shelf and the iceberg. It’s like...

New images of Earth at night

NASA just released a composite map of the world at night using satellite imagery from 2016. This is the first nighttime map since 2012, but the team behind the work hopes for bigger things with a more real-time system. For instance, daily nighttime imagery could be used to help monitor unregulated or unreported fishing. It could also contribute to efforts to track sea ice movements and concentrations. Researchers in Puerto...
