a8 a guide in preparing the wind portion of local forecasts issued at coastal
stations, but it should be borne in rnind that thc coastal and ocean-area

UNAUTHORIZED DATA IN TELEGRAPHtC REPORTS
_l__l___
Many obsorvers includc in their telegraphic reports of regular observa'
tions words for lower clouds when calm and when moving with the S~W
face wind, though is the latter case the movement is not rapid. Station
officials are enjoined to eee that tho provisions of the Weather Codc, 1931,
are obmwd in telegraphing cloud a8 wrll as other data, because the
transrnission co& of unauthorized and unnecessary data in the dietribu'
tion system are considerable in the aggregate.

BAROMETRIC CORRECTIONS FOR ALASKAN AND CANADIAN STATIONB
Inquiries hwe been received regarding the propcr corrections to be
applied to barometric readings from Almkan and Canadian stations
which are distributed through the SGL I)&A System and by teletYPe*

SETTING MARINE ANEROID8
Aneroid barometcrR on Bhjps ~hould be set by Weather Bureau employees
only under circumstanccn of the most unusual nature constitUt*
ing an cmcrgcncy cas(', anci then only at writtcn rrquest of a responsible
Hhip's ofIiccr. Evcry such caw will bc! roportcd to the Central Office.
A growing tendency to wt s~iips' bttrorneters to wro corrections has
been observed. Such action i8 rarely succwsful in cHtablkhing freed@
from a correction rating. It is objectionable in rrevcral reRpccts. The
accumulated history of a barornetcr'n corrections a8 filed in thc Centr@ 1
OfIice js n most vulunt~t~ criterion of tlie quality and con(jitjon of tha 1
barometer. Whcncvcr an aneroid is set, this history is disturbed d
uncertainties b e injwtcd which inny require a considrrablo period
time to clcnr. If the setting hun bern accomplished at Weather Bureau
hands, tht. action might rendily be rnisintcrprctcct by the mariner nR
indoracment of the accurw:y of his baroxneter, which rnay in fact be in
bad ordrv- and not truntworthy under any circumstances.
