Quarterly Radio Noise Data

June, July, August, 1964

W. Q. Crichlow, R. T. Disney, and M. A. Jenkins

Radio noise measurements are being made at eighteen stations

in a world-wide network operated in a co-operative program co-ordinated

by the Environmental Science Services Administration. The locations of

these stations are shown on the map. The results of these measurements

for the months of June, July, and August are given in this report. Where

the results for these months are not presently available, the data will be

published in subsequent reports, and the data for previous months, which

are now available but have not been published previously, are included.

The tabulated values are based on three basic parameters of the noise;

these are the mean power, the mean envelope voltage, and the mean logarithm of the envelope voltage.

The noise power received from sources external to the antenna

averaged over a period of several minutes is the basic parameter and

can be conveniently expressed in terms of an effective antenna noise

factor, fa , which is defined by:

fan= p /kT b = T /T

o a o where

p = noise power available from an equivalent loss -free

antenna (watts)

-23

k = Boltzman's constant = 1. 38 X 10 joules per degree

Kelvin

T = reference temperature, taken as 288° K

ob = effective receiver noise bandwidth (Hz)

T = effective antenna temperature in the presence of external

noise.
The antenna noise factors in this report are for a short vertical

antenna over a perfectly conducting ground plane and are expressed in

decibels, Fa

(= 10 logigfa

). This parameter is simply related to the rms

noise field strength along the antenna by:

E =F - 95. 5 + 10 logn b + 20 log f ATTT n a

&10 s

10 MHz

where:

E = rms noise field strength for bandwidth b in db above

n

°

1 uV/m

b = effective receiver noise bandwidth in Hz

f., , TT = frequency in MHz. MHz n J

The value of E for a 1 kHz bandwidth can be found from the

attached nomogram. It should be noted that E is the vertical component

of the field at the antenna. It should also be noted that the rms envelope

voltage is 3 db higher than the rms voltage.

The other two noise parameters tabulated are given relative to the

mean power. Thus, the mean voltage and mean logarithm expressed as

deviations, V, and Lj, respectively, are in db below the mean power.

Measurements of the three parameters reported were made with

the Environmental Science Services Administration's Radio Noise Recorder,

Model ARN-2, which has an effective noise bandwidth of about 200 Hz and

uses a standard 6.6294 meter (21.75') vertical antenna. A fifteen -minute

recording is made on each of eight frequencies two at a time during each

hour, and these fifteen -minute samples are taken as representing the

noise conditions for the full hour during which they were recorded. The

month -hour medians, Fam, Vj and L^j^ are determined from these

hourly values for each of the corresponding parameters. Normally from

twenty -five to thirty observations of the mean power are obtained monthly

for each hour of the day and from ten to fifteen observations of the voltage

and logarithm deviations. When there are fewer than fifteen observations

of the mean power or seven observations of the voltage and logarithm

deviations, the tabulated values are identified by an asterisk.
The upper and lower decile values of Fa are also reported in the

following tabulation to give an indication of the extent of the variation of

the noise power from day to day at a given time of day. These are

expressed in db above and below the month -hour median, Fam, and

designated by Du and D « , respectively.

In addition to these month -hour values, corresponding values

are tabulated for the time blocks as defined by CCIR Report 322. All

recorded values for the four hours of the day and the three -month period

are used to determine the median and decile values. When no data were

available for one or two months of the season, it is so indicated and should

be noted when considering seasonal trends.

The values presented in the tables reflect the actual measured

values of radio noise. The only editing for man-made noise or station

contamination of the records has been done by the station operators,

and no additional attempt has been made to identify these values by

systematic statistical means. These preliminary data values are presented in order to expedite dissemination of the data, and additional

analyses, in which an attempt is made to eliminate contaminated data,

are presented in other publications. The parameter that will first reflect

any such contamination will be the logarithmic parameter, L^. This contamination generally will cause the value of L^ to be less than it would

have been had the recorded value been only atmospheric noise. In determining the amplitude -probability distribution from the three measured

moments [ Crichlow et al. , 1960b] contaminated values of L^ may be

found that will not give a solution of the amplitude -probability distribution. When this occurs, it is suggested that the measured value of L^

be ignored and the most probable value of L^ from the curve on the graph

of L^ vs. Vd be used. The most probable value has been determined as

the best fit for the integrated moments from over sixty measured amplitude

probability distributions of uncontaminated atmospheric radio noise. The

second curve on the graph indicates the minimum value of L^ that will

give an amplitude -probability distribution with a form factor described in

the above reference and can, therefore, be used to determine whether

the measured value or the most probable value of L^ for any value of V^

should be used.

Station clocks are set to local standard time (LST) which is taken

from the time zone in which the station is located and is always an integral number of hours different than universal or Greenwich time (see

table on page 5). The data from the Floating Antarctic Research Vessel,

USNS Eltanin, are grouped so that a block 10 in latitude by 15° in longitude is treated as a separate station. The station clock in this case is
corrected to the LST at the center of the block. Because of this grouping, very few readings may be used to obtain the median values tabulated

in some cases. If, during the month, fewer than ten readings are

obtained for any one block, the decile values are not given. If data for

less than three months are used in the time block summaries, this fact

is noted on the summary sheet. Because of the small sample size,

some caution should be exercised when using these values.

the operating agencies in obtaining the data contained in this report is
