Pressure. 



The readings of the barometer were reduced to o° C. and cor- 

 rected to normal gravity. At Bergen the pressure was re- 

 duced to a height of 17.4 m. Since 1903 the observations 

 have been taken at 8 h , I4 h , and 20 h Middle Europe time 

 and means derived from the three daily readings. The 

 earlier observations were taken at other hours, in some cases 

 there being only one observation daily, but the means were 

 corrected to a uniform series. 

 Temperature. 



The monthly means of temperature at Bergen beginning with 

 1861 were computed by the formula m=n— k(n— Min.), 

 in which n is the mean of three daily observations (8 h , 14'', 

 and 2o\ 15th meridian E., since 1903), Min. is the mean 

 of the daily minima, and k is a factor which differs for each 

 month. The means of preceding years were determined from 

 observations of several different observers and were made 

 to conform as nearly as possible with the means after 1861. 



These data for Bergen are given in part III. 



BODO 



In September 1928 the station was changed to Lat. 67 ° 17' N., 

 Long. 14 26' E., H b =i~ m. Pressure and temperature are reduced 

 to the old station. There is a marked difference between the new and 

 old stations as to temperature and precipitation. 



GJESVAER 



Gjesvaer ceased as a meteorological station at the end of 1926. To 

 replace Gjesvaer a station was established at Mehavn, situated some 

 2° farther east under similar climatological conditions as Gjesvaer. 

 In December 1927 the station was removed from Mehavn to the light- 

 house Stetnes, situated some 15 km northeast of Mehavn. 



OSLO 



This station was listed in volume 79, Smithsonian Miscellaneous 

 Collections, as Kristiania (Christiania). Rainfall records ceased at 

 the end of 1927. The mean temperatures were computed by the 

 Koppen formula (see formula for Bergen).
