- EO Dashboard
The Earth Observing Dashboard showcases examples of global environmental changes for 7 themes: Atmosphere, Water and Ocean, Biomass, Cryosphere, Agriculture, Covid-19, and Economy. You can explore countries and regions around the world to see how the indicators in specific locations changed over time.

- Data from the Radio Receiver Instrument (RRI), e-POP on Cascade, Smallsat and Ionospheric Polar Explorer (CASSIOPE)
A subset of the e-POP Radio Receiver Instrument (RRI) archive pertains to ham radio experiments. This data is tagged as "Amateur Radio," "ARRL Field Day," and "HAM Radio" in the eDEx portal.

- Ionosonde
An ionosonde is a vertical sounding radar which transmits and receives electromagnetic signals in high frequency band to and from the ionosphere assuming that the signals were traveling at a speed of light. The output is the graph of virtual height against reflected frequencies which is usually called an ionogram. From the ionogram, a number of parameters such as critical frequencies of different ionospheric layers along with their corresponding heights can be obtained. These are used to study the temporal and spatial features of the ionosphere.
