The plots in the following quick-look data browser are refreshed every an hour. You can change the frequency, UT/LT and format, but the duration of plot is fixed to 24 hours. Note that data of 3925, 6055 and 9595 kHz have offsets in the central frequency (i.e., zero Doppler frequency). Some additional information for distinguishing reflections from the E and F regions is available.
If you are interested in using the data, please contact us at hfd-all-ml @ uec.ac.jp
