"Executive Summary

United States Army surgeons began taking weather observations in the Fort Marcy/Santa Fe, New Mexico area on January 1, 1849. Although Fort Marcy was “technically” located on a mesa approximately 600 yards northeast of the Santa Fe Plaza, the Army hospital, and location of the weather observations, was located approximately 300 yards northwest of the Plaza within the city of Santa Fe. The surgeons took the primary weather observations from 1849 until late 1871 when the U.S. Signal Service assumed weather observing responsibility. The longest gap of missing observations at Fort Marcy is from Mar 1, 1862 to Sep 8, 1862, generally corresponding to the time Santa Fe and Fort Marcy were occupied by Confederate troops (Mar 4 – Apr 7, 1862). Evidence indicates the surgeons continued to take weather observations after the Signal Service assumed responsibility - until February 29, 1892 - although availability of these records is limited. Unfortunately, no direct information could be found regarding type, or exposure of weather instruments used by the Fort Marcy surgeons. The most extensive information on weather observations at Fort Marcy is located in the National Climate Data Center, with the best sources of information on weather instruments in publications by the Army Surgeon General’s Office in 1844, 1850, 1851, 1856, and 1868
