Profiles of electron density 4hour average with MF radar at Yamagawa, Japan.

ResourceID
spase://IUGONET/NumericalData/NICT/SALMON/YAM/MFradar/DAE/PT4H_txt

Description
The radar transmits radio pulses vertically into the upper atmosphere at 1.9550 MHz. Returns will be produced by stratified layers and irregularities in the ionospheric D-region, to deduce height profiles of electron density 4hour average at 50 - 100 km.
