Climatic Data for Frost Protected Shallow Foundations
Publications and Data
Another publication provides the 29 winter season values that were used to compute the 100-year return period of the AFI. Data tables ( 490K or 1622K) contain the AFI value for each of the 29 winter seasons from the 1951-80 period for 3,110 cities. These data are used for applications other than FPSF.
Finding a station: To find a station in the publications use the "Find" capability (binocular icon in PDF files; in Excel files, Click Edit and then Find) and enter a city or place name.
All cities do not have Air Freezing Index values located in these files. If your city is not available, you can locate a nearby city by using a station locator system called Web Cliserv.
2) Then choose one of the Cleveland stations, possibly Burke Lakefront.
3) Then under the station name Cleveland Burke Lakefront you will see other options such as:
b) Surrounding Stations (+/-30 minutes)
5) See if one of these nearby stations has AFI values
Cautionary Note when using Air Freezing Index values: Topographic variability, proximity to bodies of water, and urban heat effects should be considered when using these data. For those locations or if the planned construction site is not located nearby a station that has AFI data, using a combination of the AFI map and the most representative city(s) AFI value(s) is advisable.
