This Series contains data on ionosphere (I) and solar radio emission (S) obtained at the following stations under the National Institute of Information and Communications Technology , Japan. approximately 26km south from the old observatory. The observation at Sarobetsu commenced on March 6, 2009. Ionospheric observations are carried out at the above four stations in Japan by means of vertical sounding using ionosondes. The ionosonde produces ionograms, which are recorded digitally on a computer storage medium. The digitally-recorded ionograms are collected from each station by the central computer and reduced to numerical values and Summary Plots by the automatic processing system. The ionograms obtained at Kokubunji are manually scaled by experienced specialists to supplement automatically-scaled parameters.
A1. Automatic Scaling
Digital ionograms  are automatically scaled by the pattern recognition method. The following five characteristics of the ionospheric are listed below. The reliability of these factors has   been   ascertained by comparison of the automatically-scaled parameters with the manually-scaled values of large amounts of test ionograms. The published data consist of tabulations of hourly values of three factors ( foF2, fEs, fmin ) and monthly medians of two factors ( h'Es ,h'F ), daily Summary Plots and monthly medians plot of foF2.
b. Descriptive Letters The following descriptive letters are used in the tables. A Impossible measurement because of the presence of a lower thin layer, for example Es ( for foF2 ). C Impossible measurement because of any failure in observation. G Impossible automatic scaling because of very small ionization density of the layer ( for fEs ). N Impossible automatic scaling because of complex echoes. Blank  No digital record because of problems occurring in the auto matic data processing system, but existence of film record. C Median count ( CNT ) is the number of numerical values from which the median has been computed. In addition to numerical values, the count may include a descriptive letter G. Median ( MED ) is defined as the middle value when the numerical values are arranged in order of magnitude, or the average of the two middle values if there is an even number of values.
IONOSPHERE
A.
Upper quartile ( UQ ) is the median value of the upper half of the values when they are ranked according to magnitude; the lower quartile ( LQ ) is the median value of the lower half. If CNT is less than 10, there are blank spaces left. d. Reliability of Automatic Scaling The results of the comparison between automatically-scaled values and manually-scaled ones showed that hourly values of foF2 , fEs and fmin were scaled within a difference of 1 MHz from about 90, 90 and 99%, respectively of the test ionograms. e. Summary Plot Daily Summary Plots which are made from quarter-hourly digital ionograms are published to present general ionosphere conditions. The upper and middle parts of a Summary Plot show the diurnal variation of the frequency range of the echoes reflected from the F and E regions, respectively. The two solid arcing lines indicate the predicted values of fxE and foE calculated by the method described in the CCIR report 340. The lower part shows the diurnal variation of the virtual height where the echo traces become horizontal.
A2. Manual Scaling
The published data consist of tabulations of hourly values of the ionospheric characteristics and figures of daily f-plot. All symbols and terminology in the tables or figures of ionospheric data are used in accordance with the "URSI of lonogram Interpretation and Reduction Hand-book ( Second Edition ) 1972 " and its revision of chapters I-4, published in July 1978.
1 Symbols b. (i)    Descriptive Letters The following letters are entered after, or used to replaced a numerical value on the monthly tabulation sheets, if necessary. Measurement influenced by, or impossible because of, A the presence of a lower thin layer, for example Es. B Measurement influenced by, or impossible because of, absorption in the vicinity of fmin. C Measurement influenced by, or impossible because of, any non-ionospheric reason. D Measurement influenced by, or impossible because of, the upper limit of the normal frequency range in use. E Measurement influenced by, or impossible because of, the lower limit of the normal frequency range in use. F Measurement influenced by, or impossible because of, the presence of spread echoes. G Measurement influenced by, or impossible because the ionization density of the layer is too small to enable it to be made accurately. H Measurement influenced by, or impossible because of, the presence of a stratification. K Presence of particle E layer. Measurement influenced or impossible because the L trace has no sufficiently definite cusp between layers. M Interpretation of measurement questionable because the ordinary and extraordinary components are not distinguishable. N Conditions are such that the measurement cannot be interpreted. o Measurement refers to the ordinary component. P Man-made perturbations of the observed parameter; or spur type spread F present. o Range spread present. R Measurement influenced by, or impossible because of, attenuation in the vicinity of a critical frequency. s Measurement influenced by, or impossible because of, interference or atmospherics. T Value determined by a sequence of observations, the actual observation being inconsistent or doubtful. v Forked trace which may influence the measurement. W Measurement influenced or impossible because the echo lies outside the height range recorded. x Measurement refers to the extraordinary component. Y Lacuna phenomena, severe layer tilt. z Third magneto-electronic component present. (ii) Qualifying Letters The following letters are entered in the first column before a numerical value on the monthly tabulation sheets, if necessary. Less than. Used only when fbEs is deduced from A foEs because total blanketing of higher layer is present. D Greater than. E Less than. l Missing value has been replaced by an interpolated value. J Ordinary component characteristic deduced from the extraordinary component. Mode interpretation uncertain. M o Extraordinary component characteristic deduced from the ordinary component. ( Used for x-characteristics only.) T Value determined by a sequence of observations, the actual observation being inconsistent or doubtful. Uncertain or doubtful numerical value. U Measurement z deduced from the third magneto-electronic component. (iii) Description of Types of Es When more than one type of Es trace are present on the ionogram, the type for the trace used to determine foEs must be written first. The number of multiple trace is indicated after the type letter. The types are: f An Es trace which shows no appreciable increase of height with frequency. l A flat Es trace at or below the normal E layer minimum virtual height or below the part E layer minimum virtual height. c An Es trace showing a relatively symmetrical cusp at or below foE. ( Usually a daytime type. ) h An Es trace showing a discontinuity in height with the normal E layer trace at or above foE. The cusp is not symmetrical, the low frequency end of the Es trace lying clearly above the high frequency end of the normal E trace. ( Usually a daytime type. ) An Es trace which is diffuse and non-blanketing over q a wide frequency range. r An Es trace showing an increase in virtual height at the high frequency end similar to group retardation. An Es trace having a well-defined flat or gradually a rising lower edge with stratified and diffuse traces present above it. s A diffuse Es trace which rises steadily with frequency and usually emerges from another type Es trace. A weak diffuse trace at heights below 95 km d as-sociated with high absorption and large fmin. The designation 'n' is used to denote an Es trace n which cannot be classified into one of the standard types. The designation 'k' is used to show the presence of k particle E. When foEs > foE ( particle E ) the Es type precedes k.
c. Definitions of the CNT, MED, UQ and LQ
Median count ( CND ) is the number of values from which the median has been computed. In addition to numerical values, the count may include certain descriptive letters. Median ( MED ) is the middle value when the numerical values are arranged in order of magnitude, or the average of the two middle values if there is an even number of values. Upper quartile ( UQ ) is the median value of the upper half of the values when they are ranked according to magnitude; the lower quartile ( LQ ) is the median value of the lower half.
