46 MONTHLY WEATHER REVIEW FEBRUARY 1933
By means of this simultaneous study of the weather and
the rapid centralization of meteorological observations by
radio there is obtained a complete survey of the weat,her from one extreme of the Republic to the other.
Each clay a t noon the Oficina Meteorol6gica de la Avia.ci6n issues through the radio station El Bosque a meteorogram witfh information of the wea,ther, a,nd fore-
casts, for each zone of the country. The weather dat,a.
are noted on blackboards and bulletin boards near the nieteorological maps. In addition to this regular service there is given to
every pilot on request a meteorogram setting forbh the
state of the atmosphere along the proposed route a t the time.
If a pilot must depart from Arica he collects information
on the state of the atmosphere t'hrough radio in a. very short time and can have an exact knowledge of the meteor- ologic.al conditions that he will encounter.
Under the Direcckh de AeronButica. there is a Secci6n
Mete.orol6gic.a in charge of statistical data and meteoro- logical observations a t the aerial bases in Chile. Meteor-
ological niaps are drawn daily, the observations made on the route sheets are entered in graphs, the elaboration of
a.eria1 naviga.tion charts is studied, pamphlets containing
meteorological instructions to pilots are published, and studies of the met8eorologic.al condit,ions along each route
a.re made public.
In the aviation school a t El Bosque there is a 2-years course in meteorology for the proper preparation of pilots.

AERONAUTICAL METEOROLOGY IN GERMANY
In my article with this title in the Monthly Weather
Review, November 1932 the date, April 1927 given for the beginning of daily airplane observations, refers to the
daily flights to 5,000 meters or higher, as now made in this country. Airplane observations a t lower levels, how-
ever, were begun in 1921 by the Lindenberg Observatory, in 1922 by the Seewarte a t Hamburg, and in 1927 by the
three other airplane observatories in Germany. St the present time (1933) 19 airport observatories in
Germany, the most important of which are in constant
communication by private wire, are furnished the three hourly reports of surface conditions a t about 200 stations; reports of the winds aloft a t about 20 pilot-balloon sta-
tions; the daily airplane observations a t Berlin, Ham-
burg, Koenigsberg, Darmstadt, and hlunich; data from
the kite station on Lake Constance, and from the captive balloon, kite, and sounding balloon flights at the Linden-
berg Aeronautical Observatory; and observations received from surrounding countries by exchange.
A diagnosis of weather conditions is prepared by each
airport observatory, from its own standpoint. This is regarded its especially important since nearly every air- way passes over one or more niountains. The aim of the
German airways service, as of course of all other such
services, is to keep pilots fully informed of the weather, actual and imminent, both before taking off and while in
flight. Information to the pilot in flight is transmitted from the broadcasting stations that serve as radio-beacons
and for place and direction finding.-Eric R. hfdler.
