Surface Weather, Signal Service and Weather Bureau

Surface Weather, Signal Service and Weather Bureau (SWSSWB) Records primarily created by the United States Army Signal Service from 1819 until the paid and voluntary stations transitioned to the Weather Bureau in the early 1890s. The collection also includes publications of the Signal Service and independent observations collected by the Signal Service during the same time period. This collection differs from the Forts collection in that records were collated by NOAA rather than the National Archives. The bulk of the collection falls in the US Army Signal Service era between 1817 and the early 1890s. However, some record types carry over into the Weather Bureau era.
