EurekAlert  December 9, 2019
At AGU’s 2019 Fall Meeting researchers unveiled the world’s largest open-access database of ELF/VLF data, Worldwide Archive of Low-frequency Data and Observations (WALDO). Researchers will be able to access nearly 1000 terabytes (TB) of data to further scientific efforts in fields like space weather, ionospheric remote sensing, earthquake forecasting, and subterranean prospecting. This is a joint project of Stanford University, Georgia Institute of Technology and the University of Colorado Denver with support from the National Science Foundation and Department of Defense. Most data are from the last 20 years, some recordings date back to the 1970s and 80s. WALDO will be a living repository, capturing ongoing data being collected by Georgia Tech and the University of Colorado Denver…read more.
