1922,03,08: although the pocket register gives a value of 28.53 inches, the NCEP analysis suggests 29.03 is better."
1922,04,26: air/grass minima swapped round cf the register
1922,05,25: register has min=619 crossed out in pencil by 569 - but this is lower than grass min
1922,07,14: thunder date might be 13th (monthly report) but RB thinks this is an error
1922,07,30: grass min changed from 503 to 453
1922,07,31: .02 in of rain appears in register but not in the monthly return
1922,09,12: NCEP analysis suggests changing pressure from 29.102/989.4 to 29.602/1006.3
1922,09,14: NCEP analysis suggests changing pressure from 29.360/998.5 to 29.036/987.6
1922,09,15: NCEP analysis suggests changing pressure from 29.952/1018 to 29.592/
1922,09,22: max temp missing - estimated as 680 by RB
1922,09,26: grass min changed from 511 to 411
1922,11,15: grass min is high - due to fog?
1922,11,21: grass min is high but air min occurred on previous day possibly so grass min prob. OK
1922,11,22: dry/wet changed from 431/435 to 435/431
1922,12,20: NCEP analysis suggests changing pressure from 28.65/974.4 to 28.95/983.6
1923,01,20: 1ft soil temp suspect
1923,01,26: max temp changed from 450 to 475
1923,01,29: 1ft and 2ft temps suspect; NCEP analyses suggest 30.5 is wrong and 30.0 is better for pressure
1923,01,30: min temp changed from 446 to 415
1923,02,15: grass min changed from 361 to 311
1923,02,20: H/T dates from monthly report; register is misleading
1923,02,28: NCEP suggests pressure too high, changed from 29.404/999.8 to 29.204/993.1
1923,03,21: min temp changed from 395 to 380
1923,04,11: grass min is high - maybe occurred in sunshine yesterday?
1923,04,15: hail not mentioned in monthly report but 'h' in register with convective cloud
1923,05,30: day described as cold like the days before and after; max temp changed from 650 to 550

1923,07,07: estimated mi temp based on nearby sites
1923,07,25: min temp changed from 615 to 565 cf other sites; register questions to 615

1923,09,01: *threatening thunder* was only reference found to one thunder day this month
1923,10,04: a large fall in temp at 1ft marked in register but not sure the reason
1923,10,24: use 28984 instead of 29984 in register for mslp cf ncep analyses
