REMARKS ---

 

 

 

 

 

 

 

 

 

 

 

 

 

Unless otherwise noted, all January-March 1881 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 during the first three months of 1881.

 

 

 

 

 

 

 

 

 

 

 

 

 

In addition to the tri-daily fixed time readings, Ft. Snelling observers took readings from self-registering

 

 

 

 

 

 

 

 

 

 

 

 

 

maximum-minimum thermometers, beginning 1 April 1881 and continuing through the remainder of the year.

 

 

 

 

 

 

 

 

 

 

 

 

 

The April-December portion of the 1881 record, accordingly, includes averages and extremes taken BOTH from

 

 

 

 

 

 

 

 

 

 

 

 

 

the fixed time record and the maximum-minimum record. Monthly averages derived from the fixed time record were

 

 

 

 

 

 

 

 

 

 

 

 

 

calculated in the same manner as were corresponding averages for the years 1877-1880. None of the foregoing

 

 

 

 

 

 

 

 

 

 

 

 

 

average temperatures have been adjusted to the standard NWS 2400-2400 hour observation day.

 

 

 

 

 

 

 

 

 

 

 

 

 

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 29 September. Lowest 1881 temperature

 

 

 

 

 

 

 

 

 

 

 

 

 

recorded at 0700 hours on 9 January. January-March and December 1881 precipitation record is missing/incomplete.

 

 

 

 

 

 

 

 

 

 

 

 

 

Highest 1881 temperature recorded on 11 August.
