Site. 



A Kew barometer has been in use, its height being 65 ft. above 



mean sea level. 

 The rain gage and thermometer screen have been 65 ft. above 

 mean sea level, not 90 ft. as indicated previously. These were 

 shifted on July i, 1940, from the position near the Residency, 

 a distance of approximately 150 yds., to the vicinity of the 

 radio station. The altitude and conditions of exposure are 

 unchanged. 

 Hours of Observation. 



Observations were made at 8'^ until August 13, 1939; thereafter 

 at f" 40™ local time.

 Temperature. 



Since 1933 the thermograph has been in a new Stevenson screen 

 of approved pattern at a height of 4 ft. above the ground. 

 The readings of the thermograph have been corrected by 

 control thermometers which are still exposed in the old screen 

 at a height of 1.75 m. The hourly temperature readings are 

 still therefore in terms of readings at the old height. 

 Precipitation. 



The rain gage height is now 0.65 m. ; it was previously shown as 

 0.75 m. The cause of the change is unknown — possibly a 

 general elevation of the ground due to wind-blown sand. The 

 height of 0.65 m. has been fairly constant during the last 

 3 years. 



Exposure of Thermometers in Samoa (Air Department, New 

 Zealand, Meteorological Office Note No. 25). 



The first thermometer screen at the Apia Observatory was erected 

 toward the end of 1902. The site chosen was about 30 ft. from the 

 seashore and toward the northern edge of a cleared space, about 100 ft. 

 in diameter, which was level and fringed with young, low coconut 

 palms. When the screen was replaced, the new one was erected on 

 the same spot, and hence the original site is still in use today. The sur- 

 roundings, however, have been altered to some extent since 1902. 

 At first new coconut trees were allowed to grow nearby, about 20 ft.
