ILRS Virtual World Tour of SLR Stations

NASA’s CDDIS supports the International Laser Ranging Service (ILRS), and invites you to virtually visit five satellite laser ranging (SLR) stations on five continents in five days! Red stars indicate ILRS World Tour stations (the fifth station in Yarragadee, Australia, is not shown).

SLR Station Locations

Laser ranging distance (station to satellite and back) and time observations are formatted at remote sites, then transmitted to operational data centers where they are merged before being sent for archiving at global data centers such as NASA’s Crustal Dynamics Data Information System (CDDIS).


NASA's data policy ensures that all NASA data are available fully, openly, and without restrictions. Here's what this means to you.

What is Data Latency?

Several factors affect the speed at which data are processed and made available to users. Here's how NASA's Earth Observing System Data and Information System (EOSDIS) defines data latency.

User Profile: Dr. Paul Siqueira

The ability for Synthetic Aperture Radar (SAR) to create high-resolution imagery regardless of atmospheric conditions makes it a key technology for studies of change over time. Dr. Paul Siqueira’s work improves these sensors and the Earth observing data they collect.

Keeping NASA EOSDIS Data Flowing (Even When the World is Telecommuting)

EOSDIS strategies for processing, archiving, and distributing NASA Earth observing data ensure that data are constantly available to global data users – regardless of world events.

New Saildrone Dataset at NASA’s PO.DAAC

Data from the Atlantic Tradewind Ocean-Atmosphere Mesoscale Interaction Campaign (ATOMIC) shed new light on ocean-atmosphere interactions.

How Birds Respond to Extreme Weather

Extreme weather events such as heat waves and drought affect the presence of certain bird species.
