REMARKS --- |
|
|
|
|
|
|
|
|
|
|
|
|
|
Unless otherwise noted, all 1880 data are from fixed time observations taken daily at the Ft. Snelling |
|
|
|
|
|
|
|
|
|
|
|
|
|
post hospital station at 0700, 1400 and 2100 hours local time. So far as can be determined, the station was |
|
|
|
|
|
|
|
|
|
|
|
|
|
not equipped with self-registering maximum-minimum thermometers at any time during 1880. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Foregoing average temperatures include the averages of fixed time observations taken at 0700 and 1400 hours. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Average monthly temperatures were calculated by taking the sum of the daily 0700 hour and 1400 hour readings |
|
|
|
|
|
|
|
|
|
|
|
|
|
plus twice the sum of the 2100 hour readings and dividing the resulting sum by four. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Extreme maxima and extreme minima are the highest and lowest values OBSERVED at the Ft. Snelling station |
|
|
|
|
|
|
|
|
|
|
|
|
|
during the month involved. Monthly average temperatures have NOT been adjusted to the NWS 2400-2400 hour |
|
|
|
|
|
|
|
|
|
|
|
|
|
observation day. Highest 1880 observed temperature was recorded at 1400 hours on 13 August. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Monthly mean cloudiness values are the averages based on visual sky cover observations taken daily at 0700, |
|
|
|
|
|
|
|
|
|
|
|
|
|
1400 and 2100 hours local time. A cloudiness value of zero (0) indicates a totally clear sky: a value of five indicates |
|
|
|
|
|
|
|
|
|
|
|
|
|
50 percent cloud cover, etc. Greatest daily precipitation recorded on 18 September. Lowest 1880 temperature |
|
|
|
|
|
|
|
|
|
|
|
|
|
recorded at 0700 hours on 28 December. November-December 1880 precipitation record is incomplete. |
|
|
|
|
|
|
|
|
|
|
|
|
|
November 1880 greatest daily precipitation value is inferred from a partial record. |
