Authority. 



India Meteorological Department, Poona, India. 

 General Remarks. 



Data correspond to previously published data in Smithsonian 

 Misc. Coll., vols. 79 and 90. Whenever there were changes 

 in site or exposure, the later data have invariably been re- 

 duced to the original site or exposure by applying correc- 

 tions derived from comparative observations. Such cor- 

 rections for temperature and rainfall are given in a separate 

 table (table i), page 19. 



The values of latitude and longitude of many of the stations have 

 been slightly changed owing to redetermination. The latest 

 values are given in the tables printed in this volume. 



The times of observations in the case of stations in Burma, viz., 

 Akyab, Mandalay, Mergui, and Rangoon, are given in 

 Burma Standard Time (B.S.T.) which is i hour in advance 

 of Indian Standard Time (I.S.T.), as there is an independent 

 meteorological service now for Burma. 



At all the observatories of this department, the thermometers are 

 kept 4i to 4^ ft. above the ground, and the rim of the rain 

 gage I ft. above the ground. The exceptions are noted in 

 each case with the data. 



ALLAHABAD 



Site. 



The site of the observatory was changed on October i, 1939. 

 Exposures are different, and corrections to reduce tempera- 

 ture and rainfall data of the new site to the old site are not 

 yet available. Hence data after the shift have been given 

 without correcting. For the same reason the annual means 

 for 1939 have not been given. 

 Pressure. 



Owing to the change of site, the Hb was changed from 309 ft. 

 to 322 ft. on the date mentioned above. Pressure data from 

 October 1939 to December 1940 have been reduced to the 

 old Hb of 309 ft.
