YEAR: 1879

 

 

 

 

 

 

 

 

 

 

 

 

 

REMARKS ---

 

 

 

 

 

 

 

 

 

 

 

 

 

Unless otherwise noted, all 1879 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 1879.

 

 

 

 

 

 

 

 

 

 

 

 

 

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 1879 observed temperature was recorded at 1400 hours on 29 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 3 July. Lowest 1879 temperature

 

 

 

 

 

 

 

 

 

 

 

 

 

recorded at 0700 hours on 25 December. July 1879 precipitation record is probably incomplete.

 

 

 

 

 

 

 

 

 

 

 

 

 

When they appear in the foregoing tables, ITALICS indicate estimated / derived and/or incomplete values.
