 Pressure. 



Site: The height of the barometer above Mean Sea Level was : 



1921 January 11.3 m 



1921 February-1930 25.0 m 



All values have been reduced to Mean Sea Level by applying 

 the following corrections : 



1921 January + 1.0 mm 



1921 February-1930 +2.3 mm 



Hours: The values of pressure do not refer to a fixed hour, but 

 are the mean values of three to six observations 

 a day. The diurnal variation is negligible in com- 

 parison with the variation from month to month. 

 Notes: All values have been corrected to normal gravity (Lat. 

 45 ) by applying a correction of +1.3 mm. 

 Temperature. 



Hours: The hours of observation were 8 h and I4 h throughout. 

 Means: The values are the means of daily observations at 8 h and 

 I4 h and i(8 h +i4 h ). 

 Precipitation. 



The height of the rim of the rain gage above the ground is 1.9 m.

 Pressure. 



Site: All values have been corrected to Mean Sea Level by apply- 

 ing a correction of +1.6 mm. 

 Hours: The values of pressure do not refer to a fixed hour, but 

 are the mean values of three to six observations a day. The 

 diurnal variation is negligible in comparison with the varia- 

 tion from month to month. 

 Notes: All values have been corrected to normal gravity (Lat. 

 45°) by applying a correction of +1.2 mm. 

 Temperature. 



Hours: The hours of observation were 8 h and i4 h throughout. 

 Means: The values are the means of daily observations at 8 h and 

 i4 h and |(8 h + i4 h ).
