Aeolus: Wind-mapping space laser is losing power

13 May 2019

Europe's Aeolus satellite was launched last year to gather data to improve weather forecasts, and its observations have unquestionably proved their worth.

However, the laser is now degrading and has already lost half its power.

Two decades of change at Pine Island Glacier

Images of Pine Island Glacier, Antarctica, were acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite from 2000 to 2019. Images show a wide view of Pine Island Glacier (PIG) and the long-term retreat of its ice front.

NASA's GRACE: What We've Learned from Water in Motion

13 May 2019

When you hear news about ice loss from Greenland or Antarctica, an aquifer in California that is getting depleted, or a new explanation for a wobble in Earth's rotation, you might not realize that all these findings may rely on data from one single mission: the U.S.-German Gravity Recovery and Climate Experiment (GRACE).

Joining forces on Earth science to benefit society

13 May 2019

With human activity leaving its indelible mark on the landscape and affecting the climate, our natural world is changing faster than at any other time in history. Science is fundamental to understanding environmental change so that these huge challenges can be tackled. To ensure a more efficient approach on Earth-system science and to bring direct benefits to society, ESA and the European Commission are working to join forces.

Advanced Webinar: Integrating remote sensing into a water quality monitoring program

5, 12 and 19 June 2019

Organisation: NASA Applied Remote Sensing Training Program (ARSET)

Overview: With a focus on integrating NASA Earth observations into water quality monitoring decision making processes, this advanced webinar series will include a brief overview of data products used for water quality monitoring, an overview of aquatic remote sensing-specific criteria, methods and best practices, obtaining NASA Earth observation data for water quality monitoring, and practical skill building in image processing for water quality monitoring of coastal and larger inland water bodies. Weekly, two hour webinars will include lectures, hands-on demonstrations, written instructions to conduct exercises, and a question and answer session. After the third part, participants are invited to participate in an optional, additional two-hour period of unstructured "laboratory" time. Participants will have the opportunity to work on exercises and submit questions to the instructors.

Learning Objectives: By the end of this training, attendees will be able to:

  • acquire relevant remotely-sensed imagery and products
  • apply best practices for atmospheric correction to remotely-sensed images
  • evaluate the uncertainty of images by validating satellite imagery using in situ measurements
  • analyse water quality data using NASA's SeaDAS software and validate aquatic remote sensing data products
