Notes:
Charles G. Abbot (1872-1973), the fifth Secretary of the Smithsonian Institution, came to the Institution in 1895 as an assistant to Secretary Samuel P. Langley in the Smithsonian Astrophysical Observatory. In 1907 he was named Director of the Astrophysical Observatory, a position which he held until his retirement in 1944. He became an Assistant Secretary of the Institution in 1918, and served as Secretary from 1928 to 1944. Most of Abbot's research centered around studies of solar radiation and attempts to determine the relationship between solar variations and the earth's weather

Historical Note

Charles G. Abbot (1872-1973), the fifth Secretary of the Smithsonian Institution, came to the Institution in 1895 as an assistant to Secretary Samuel P. Langley in the Smithsonian Astrophysical Observatory (SAO). In 1906 he was named Director of the Astrophysical Observatory, a position which he held until his retirement in 1944. He became an Assistant Secretary of the Institution in 1918, and served as Secretary from 1928 to 1944. Most of Dr. Abbot's research centered around studies of solar radiation and attempts to determine the relationship between solar variations and the earth's weather.

ASTROPHYSICAL OBSERVATORY CHARTS, 1920-1955.

In the solar constant work of the Astrophysical Observatory, four main instruments were used: The spectrobolometer, the pyranometer, the pyrheliometer, and the theodolite. The spectrobolometer was used to make autographic recordings of the relative intensities of the solar rays which make up the solar spectrum. These graphs are called holographs. The pyranometer was used for measuring sky brightness (it measures the intensity of the so-called "solar aureole"). It was used because of a relationship which was discovered between atmospheric transmission. The pyrheliometer was used to determine the direct solar beam intensity. The theodolite was used for determining the sun's altitude above the horizon so that the so-called "air mass" can be determined.

Pyrheliometry, pyranometry, and theodolite measurements are recorded in the wastebooks (Series 5). There are a few exceptions, however, because the wastebooks pertaining to Washington, D. C. and Mt. Wilson do have some spectrobolometric data and atmospheric transmission measurements recorded. The charts (for Montezuma & Table Mountain) contain everything, spectrobolometry, pyrheliometry, pyranometry, etc.

It must be remembered that there will be exceptions because over a 50 year work span procedures did change.

Some wastebooks are copies instead of originals. This is due to the fact that during a period of the solar constant work observers would set the page in the record book in the following manner. Over the appropriate page in the wastebook a carbon-paper and another sheet would be attached with paper clips. They would then record their observations and would thus have a permanent copy for the observing station and a removable one which would be sent to the APO in Washington, D. C.

It is obvious that two wastebooks were used in recording a days observations. One wastebook contained pyranometry, psychrometry, times of start and finish of the holographic record, and the weather conditions. The other book would contain the pyrheliometry and the theodolite measurements. Then, of course, the holographic plates were kept (Series 23), thus giving spectrobolometric records.

The plates were then read at different positions (that is, the heights of the curves at different positions were determined). All of the data was then used in the reduction of the solar constant. This was either done at the station or in Washington, D. C. The plate readings were recorded on chart paper. The charts contain the accumulated data and the final reductions for Mt. Montezuma and Table Mountain (Both long and short methods). The charts are the final product.

For further explanation of the charts see Appendix 1 (in control file).

ASTROPHYSICAL OBSERVATORY DAY BOOKS AND YEAR BOOKS, 1889-1907.

The Year Books and Day Books were daily logs and record books kept by APO staff. Entries are spotty. Among those who made entries were Samuel P. Langley, Charles G. Abbot, R. C. Child, and F. E. Fowle, Jr. Included are brief notes concerning replacements of equipment, work done on special equipment, and daily activities. Some entries include inventories and lists of shipments received.

ENERGY SPECTRUM BOOKS.

The Energy Spectrum books seem to consist of spectrobolometric data from Washington, D. C. (ca. 1892-1917) and Allegheny Observatory (ca. 1882-1886). The starting and stopping times for the various plates, and sometimes the plates, settings, are given. Volume I (page 49) includes an explanation of terms used. Volume II contains instructions given by Langley for bolometry observations.

Box 131

Vol. I, May 13, 1892-May 26, 1894. Refers to Washington, D. C. unless specified. Includes a few wet & dry and barometer readings, and perhaps some Bolometry.

Series 5

ASTROPHYSICAL OBSERVATORY WASTEBOOKS, CA., 1890-1950.

For an explanation of Wastebooks see description of Series 2.

The Wastebooks contain weather information and data from the various APO observing stations. These data were used in determining the "solar constant." Graphs of results obtained are often in the backs of the books. The first few volumes contain information on instruments and the observatory layout of the Washington, D. C., station. It is assumed that (at the least) the first 34 volumes originated in Washington, D. C., since no other observing stations existed until 1905. In many of the early books dates around 1926 were found, probably because the books were being reviewed with the intent of publishing some of the data. It was noted if the wastebooks were originals or copies. Also noted were pages containing wet and dry readings taken by a sling psychrometer. Also tables of t and t' with R. H. noted (presumably t and t' are wet and dry readings). Only a few vapor pressure and no air pressure readings were seen. Wastebooks which have wet and dry readings throughout are circled.
