REMARKS --- |
|
|
|
|
|
|
|
|
|
|
|
|
|
Unless otherwise noted, all 1869 data are from observations taken at the Ft. Snelling post hospital station. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Average monthly maximum, average monthly minimum and average monthly temperatures are from self-registering |
|
|
|
|
|
|
|
|
|
|
|
|
|
maximum-minimum thermometers. So far as can be determined these instruments were first used at the Ft. Snelling |
|
|
|
|
|
|
|
|
|
|
|
|
|
station on 25 October 1869 and were read and re-set at about 0700 hours each day. |
|
|
|
|
|
|
|
|
|
|
|
|
|
The foregoing fixed time averages are from fixed time observations taken daily at |
|
|
|
|
|
|
|
|
|
|
|
|
|
0700, 1400 and 2100 hours. These averages were computed by taking the sum of the 0700 and 1400 hour readings |
|
|
|
|
|
|
|
|
|
|
|
|
|
plus twice the sum of the 2100 hour readings and dividing the resulting sum by four. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Observed monthly maxima and minima, January-24 October, are from fixed time readings taken at 0700, 1400 |
|
|
|
|
|
|
|
|
|
|
|
|
|
and 2100 hours. Beginning 25 October 1869, extreme monthly values are from the station's self-registering |
|
|
|
|
|
|
|
|
|
|
|
|
|
thermometers. So far as can be determined, no mean cloudiness records were kept at Ft. Snelling during 1869. |
|
|
|
|
|
|
|
|
|
|
|
|
|
NONE OF THE FOREGOING AVERAGE TEMPERATURE VALUES HAVE BEEN ADJUSTED TO THE STANDARD |
|
|
|
