New Publication in GeoHealth: Quantifying Human Health Benefits of EO

The authors Signe Stroming, Molly Robertson, Bethany Mabee,  Yusuke Kuwayama, and Blake Schaeffer are pleased to announce their newly published GeoHealth paper entitled: Quantifying the Human Health Benefits of Using Satellite Information to detect Cyanobacterial Harmful Algal Blooms and Manage Recreational Advisories in U.S. Lakes.  This article fills in the previously missing quantitative estimate of the socioeconomic benefits generated from earth observation detection of cyanoHABs and managing recreational advisories at freshwater lakes.

Now Available! Merged Satellite Products for the ECV – Lakes

Now Available! The first version of merged satellite products for the ECV – Lakes

The ESA Lakes Climate Change Initiative (Lakes_cci) project team is happy to inform that the first version (1.0) of merged satellite products is accessible at:

This dataset contains global lake products for the following five thematic Essential Climate Variables:
– Lake Water Level (LWL)
– Lake Water Extent (LWE)
– Lake Surface Water temperature (LSWT)
– Lake Ice Cover (LIC)
– Lake Water-Leaving Reflectance (LWLR)

Main Data characteristics:
– Spatial coverage: 250 lakes spread over the world
– Spatial resolution: Grid 1/120 degree
– Temporal resolution: Daily.
– 1 netCDF file per day containing all parameters
– Temporal coverage: From 1992 up to 2019 (shorter ranges for some parameters).

GEOAquaWatch Announces Community Discussion of Analysis Ready Data

Dear GEO AquaWatch Community,

On May 20th, 2020 we invited you to participate in a community discussion focused on the challenges and opportunities of EO-based Aquatic Analysis Ready Data (ARD) for water quality monitoring and assessment. We define ARD as the systematic radiometric, atmospherically, geometrically and spatially corrected full archive EO data sets of normalized water leaving radiance or reflectance. The objectives of this meeting were to explain the concept of ARD, show examples of aquatic ARD, unique challenges related to implementing ARD in aquatic systems, progress and products to date, and enlist members for an ad hoc Aquatic ARD committee. Here you’ll find an agenda and  Discussion Document.   You can view the video of the community discussion here.

Thank you!

Sent on behalf of GEOAquaWatch Leadership Arnold Dekker, Paul DiGiacomo, and Steve Greb.


Great Lakes Observing System Data Providers Webinar

Join GLOS for this webinar on April 8th at 1pm EDT!  REGISTER HERE

What’s the webinar about?
The past year has seen an exciting one at GLOS: new staff, new technology, new partnerships, and a new strategic plan to guide the organization through 2025 in support of the Smart Great Lakes Initiative.

Along with the newness has come some important questions from our partners: What does the new strategic plan mean for existing efforts? What new opportunities exist for partnership? How can I leverage GLOS to improve my work and contribute to the overall observing system?

The new strategic plan was crafted to improve the caliber of end-to-end data services GLOS is able to offer to the Great Lakes region, and providing those services means collaborating closely with current and future data providers—those deploying the sensors, buoys, and other technologies that enable us to monitor and understand our lakes.

Tune in to hear an update on how GLOS is working to support monitoring, how to contribute to the new Integrated Ocean Observing System proposal, practical next-steps for sharing your data, and more.

This is an open webinar. Please share with anyone who may be interested in attending.

Hope to see you there, and do reach out with any questions, or visit
