HIGH FREQUENCY (3-30 MC/S) ATMOSPHERIC RADIO NOISE DATA

Donald L. Lucas and John D. Harper, Jr.

Geographic and frequency dependent distributions

of atmospheric noise power enumerated in CCIR Report

322 [1964] are approximated by series expansions for

use in electronic computers. Coefficients of Fourier

series representation of worldwide geographic dependence and power series representation of both mean and

decile variability of the frequency dependence are tabulated. Representative contour charts of all distributions

are shown along with sample longitudinal and latitudinal

variations. (Key words: Numerical, representation,

high frequency atmospheric, radio, noise, computer)

1. INTRODUCTION

Minimum signal levels required for satisfactory radio communications depend upon the radio noise level at the receiving antenna. One

of the important noise parameters in high frequency communication

systems (3-30 Mc/ s) is atmospheric radio noise. The internationally

accepted method of predicting atmospheric noise is outlined in International Radio Consultative Committee Report 322 [CCIR, 1964].

The atmospheric noise maps in the above report are average values

of the noise to be expected in a given season of the year within discrete

four-hour time blocks. A frequency dependence is given for each fourhour time block along with the expected variability of the noise. The

variability is shown in the form of the upper and lower decile (Du & D't).

Since computer methods have become prominent in predicting

system performance of high frequency communication circuits, [JTAC,

1964] a numerical representation of CCIR Report 322 in the form of series

expansion coefficients is. extremely useful to the efficient solution of these
problems. The representation of the atmospheric noise data from CCIR

Report 322 for computer solution of high frequency systems problems is

the object of this report. An estimate of galactic noise is not included

in this report.

The numerical coefficients which represent the worldwide distribution of atmospheric radio noise as a function of geographic location

were generated by means of a least squares fit using Fourier analysis.

The maps of frequency dependence and variability of the radio noise

were generated using a power series least squares fit. Short term

variability of the radio noise is not included.

Some geographic smoothing in the noise maps is not considered

detrimental in high frequency systems problems since the CCIR maps

are based on nondirective antennas, while most communication circuits

employ directive antennas which may be directed into a noise center when

in a quiet location, or may be directed away from the noise center when

in a high noise area. The numerical methods in this report introduce

some geographic smoothing due to the truncation of the Fourier series.

The numerical coefficients contained in this report are available

on magnetic tape and can be obtained from the National Bureau of

Standards, Boulder, Colorado.

2. REPRESENTATION OF GEOGRAPHIC DISTRIBUTION

BY FOURIER SERIES

The procedure for representing a function, f(x), by means of a Fourier series may be found in many texts on numerical analysis,

[e. g. , Milne, 1949].

The representation of the CCIR geographic noise distribution

(hourly median amplitudes at 1 Mc/ s) by means of Fourier coefficients

was obtained by two separate harmonic analyses on the computed points

from which the CCIR maps were drafted. The first analysis describes

the latitudinal variations.
From longitudes spaced approximately four degrees apart, data

were selected at intervals of less than two degrees of latitude.

A linear interpolation between selected points was done to yield

n + 1 =361 data points:

Y

R

=f (kh), (k= 0, 1, 2, 3 ... , n),

taken at equal intervals,

x •= 0, h, 2h, . . . , nh =1 TT

.

(The selected points were taken sufficiently close together to yield good

approximations for the equally spaced Y . ) Thus the latitude scale has

been transformed from -90° £ x ^ 90° to ^ TT

.

Following the procedure of Lanczos [1956], since f (0) £ f (n), we

define:

g (x) = f (x) = (a + 3 x ) £ x £ I

g (x) = -g (-x) _t < x^ 0,

where CX and 3 are chosen in such a manner as to satisfy the boundary

conditions

g (0) = 0, g

(I) = 0,

thus obtaining a periodic function g (x) which is continuous and has a continuous derivative. This procedure insures a much faster convergence

of the Fourier expansion of g (x) than that which would be obtained

directly from f (x) . The function g (x) is then developed into a pure sine series of the

form:

TT 2 tt in

g (x) = bi sin — x + b2 sin —g- x + ... + b. sin —g- x + .... t t

(1)

First, modify f (x) = Y to

g (x) , t (x) . i ,o) . m^isi) x
and then determine the b. of the expression (1) by means of:

n - 1 2 ST

1 TT b. = — > g (jh) sin ij - , i = 1, . . . , 29.

l n z_i n

J = 1

The number of coefficients, for representing the latitudinal variation,

(K = 29), was determined for data having the widest variation. The

method of "cutoff frequency" as discussed by Lanczos L 1 956 , pp. 336f]

was used. The first step, therefore, yielded a series of 29 coefficients

for each of the chosen longitudes.

Figure 1 describes graphically the degree of fit obtained using the

truncated series of 29 coefficients. Two discrete curves are shown:

(1) the original data as scaled are represented by asterisks, and (2)

the numerical curves, which are secured from equation (1) are represented by periods. The asterisks are shown only when the original datum

deviated from the fitted curve by one half decibel or greater.

The second step in the generation of coefficients to represent the

geographic distribution was to do an harmonic analysis of the longitudinal

variation of the coefficients b. developed in step one. The longitude scale

was transformed into ^ x ^ TT by proceeding in an eastward direction from

0° longitude in order to obtain the expansion in a pure sine series.

The procedure outlined in step one above was followed with two

exceptions. First, since f (0) = f (TT), a single constant X = f (0) is

subtracted from f (x):

g (x) = f (x) - X .

Secondly, it was found that the series could be terminated at 1 5

harmonics to yield a satisfactory representation of the b.. An analysis

of 4368 evenly spaced coordinates selected from within the 24 geographic
maps produced an average absolute deviation of 0. 276 decibels between

the numerically mapped values and the values from CCIR 322. The

maximum error encountered was 3. 17 decibels which is well within the

tolerance of the original recorded data used in this analysis. Typical

graphic representation of the fit of the b. obtained is shown in figure 2.

Contour maps of worldwide 1 Mc/ s noise produced from the generated coefficients are shown in the odd-numbered figures 3 through 49.

A Fortran program which will evaluate the 1 Mc/ s atmospheric

radio noise is given in Appendix I. The coefficients appearing in tables 2 through 2 5 are used with the

above program in the order shown in table 1.

3. REPRESENTATION OF THE FREQUENCY DEPENDENCE

BY POWER SERIES

The frequency dependence curves of the median amplitude of atmospheric radio noise given in CCIR Report 322 were obtained by a least

squares fit to the function:

2 6

Y (X, N) = A (N) + A (N) X + A (N) X + . . . + A (N) X

where

A.(N) = b.

2 + b.2

N, i •= 1, ..., 7,

N = median amplitude of the 1 Mc/ s atmospheric radio

noise (dB > ktb), and

v 8x2 lQglo£

- 11 , X = 4

where f is operating frequency - Mc/ s, subject to the following

constraint j Y (-3/4, N) = N (i.e. , the median amplitude reduces to N when

f is set equal to 1 Mc/ s).
The upper half of even -numbered figures 4 through 50 represent

evaluations of the above function by the Fortran II routine presented in

Appendix II. The region above 20 Mc/ s was not verified by actual

observations, but results from an extrapolation of the fitted data.

4. REPRESENTATION OF THE VARIABILITY OF

RADIO NOISE (Du & Dl) BY POWER SERIES

CCIR Report 322 curves representing upper decile (Du) and lower

decile (D£) values of the distributions were generated by a least squares

fit to the function:

Y (X) = An + A X + A X

2 + A, X3 + Ar X

4 12 , 3 4 5

where , Y (X) = Du or D-t in decibels above or below the median

amplitude, X = log 10 (f), and

f = operating frequency - Mc/s.

A Fortran II routine which will evaluate this function is located in

Appendix II. The lower half of even -numbered figures 4 through 50 are

illustrations of evaluations. Tabulated coefficients appear on pages

85-87.

5. EXAMPLE OF THE USE OF CHARTS

The radio noise charts appearing in figures 3 through 50 were not

intended for manual calculations; however, numerical solutions by the

computer can be roughly checked using them.

Example: find the predicted amplitude of the median and decile

values of the atmospheric radio noise at Boulder, Colorado, at 0200 LMT

in January using an operating frequency of 10 Mc/ s. Step 1. Enter figure 3 with geographic coordinates of Boulder

(105W-40N). Read 1 Mc/ s atmospheric noise amplitude

of 63 dB > ktb.
Step 2. Enter Northern Hemisphere Frequency Dependence Chart

of figure 4 with 63 dB > ktb at 1 Mc/ s and operating frequency of 10 Mc/s. Read amplitude of atmospheric radio

noise of 170 dB < 1 watt in a 1 c/ s band at 10 Mc/ s. Step 3. Enter Northern Hemispheric Distribution Chart of figure 4

with 10 Mc/ s. Read upper decile value of the amplitude of

atmospheric noise of 5 dB above the median and a lower

decile value of 4 dB below the median. Thus the upper

decile is 165 dB < 1 watt and the lower decile is 174 dB

< 1 watt in a 1 c/ s band.

6. CONCLUSIONS

A numerical representation of the atmospheric noise is practical,

efficient, and essential for computer solution of high frequency systems

problems

.

This numerical representation should prove valuable to the radio

systems engineers interested in a computer evaluation of the atmospheric

radio noise and its distribution. The accuracy of the numerically

represented values as presented is adequate for practical prediction

routines in use today.

APPENDIX I

EVALUATION OF FOURIER FUNCTIONS

FOR GEOGRAPHIC DISTRIBUTIONS

The Fortran II subroutine for calculating values of atmospheric

noise as a function of geographic latitude and longitude is tabulated on

the next page. It uses the addition formula

sin iX = sin (i-1) X • cos X + cos (i-1) X • sin X.

The variables appearing in the subroutine are:

KJ = index of hour block maps

XLA = geographic latitude of receiving antenna - degrees

CEG = geographic longitude of receiving antenna - degrees

ANOS = value of expected 1 Mc/ s atmospheric radio noise - db > ktb

P = matrix of Fourier coefficients

ABP = matrix containing alpha and beta

ZZ = list containing generated coefficients in latitude

EVALUATION OF THE POWER SERIES FUNCTIONS REPRESENTING

THE FREQUENCY DEPENDENCE AND VARIABILITY MAPS

The routine for calculating values of frequency dependence and

variability as a function of frequency follows on the next page.

The variables appearing in the subroutine are:

X2 = geographic latitude of receiving antenna

IBLK = index of hour block and hemispheric maps

FREQ = operating frequency - Mc/ s Z = median value of atmospheric radio noise (1 Mc/ s)

db > ktb

FA = median value of atmospheric radio noise at

operating frequency - db > 1 watt

Du = upper decile value of atmospheric radio noise at

operating frequency - db > median value

D! = lower decile value of atmospheric radio noise at

operating frequency - db < median value
