The stations followed by letter A are airport stations, all others are city office stations and are followed by letter C. c Col. 3. The elevations marked c are ground elevations of the station. All other elevations given are the actual elevations of the thermometer bulb above mean sea level. _ d Col. 4. The periods ofrecord indicated apply only to the lowest temperature ever recorded shown in Col- 5, and generally extend from a summer month of tne hist year indicated through the spring months of the last year indicated. The periods marked by * terminated in December of the year indicated; e Average of readings of one lowest temperature obtained for each year. For period October to April, inclusive. ,.8 It should be noted that Col. 8 applies only to airports, as these data for city stations are not available.at this time. The temperature shown is the minimum hourly out-door temperature which has been equalled or exceeded 97J4 percent of the total hours in December, January and February for the period of reconi. It is pointed out that in most cases the airport stations are outside of the city and these data would apply primarily to rural areas. , Col- 9 indicates the maximum wind velocity which occurred at temperatures the same as, and lower than, the temperatures shown in Col. 8. . 1 Col. 10 records design temperatures in use by A-S.H.V.E. Members as reported by Chapter Secretaries for the various stations. Where these were not available the design temperatures from an ACRMA publica tion and various other sources have been inserted. .. J The wind velocities indicated in Col. 11 were furnished by the U. S. Weather Bureau and corrected through Feb. 1948. . * A bulletin prepared by AB.H.V.E. and U. S. Weather Bureau for annual weather data of city of Detroit indicates 6 as design temperature based on Dec. to March, inclusive. m Computed for Heading by Karl SheUey and O. F.
