Daily Weather Data (Precipitation, Minimum and Maximum Air Temperatures) of Florida, Parts of Georgia, Alabama, and South Carolina,1895-1915

September 14, 2017

This data release consists of Network Common Data Form (NetCDF) data sets of daily total-precipitation and minimum and maximum air temperatures for the time period from January 1, 1895 to December 31, 1915. These data sets are based on individual station data obtained for 153 National Oceanic and Atmospheric Administration (NOAA) weather stations in Florida and parts of Georgia, Alabama, and South Carolina (available at http://www.ncdc.noaa.gov/cdo-web/results). Weather station data were used to produce a total of 23,007 daily raster surfaces (7,669 daily raster surfaces for each of the 3 data sets) using a thin-plate-spline method of interpolation. The geographic extent of the weather station data coincides with the geographic extent of the Floridan aquifer system, with the exception of a small portion of southeast Mississippi where the Floridan aquifer system is saline and not used.Daily precipitation meteriological data were converted from tenths of mm to inches. Precipitation data were evaluated for outliers and quality control was applied. Data were excluded if values were -9999, no data, or less than 0.00 inches of rain. Recorded precipitation ranged from 0.0 inches, multiple days, to 18.29 inches on August 29, 1911 in Saint George, GA weather station. Median precipitation was 0.0 inches.
Daily minimum temperature meteriological data were converted from tenths of degrees Celsius (C) to degrees Fahrenheit. Minimum-temperature data were evaluated for outliers and quality control was applied. Data were excluded if values were greater than 100 F or less than -19F. Recorded minimum temperature ranged from -18.04 F on February 14, 1905 at the Valley Head, AL weather station, to 96.08 F, several days, all during the month of August, one weather station of GA and another one from FL. Median of minimum temperature was 57.92 F. Daily maximum temperature meteriological data were converted from tenths of degrees Celsius (C) to degrees Fahrenheit. Maximum-temperature data were evaluated for outliers and quality control was applied. Data were excluded if values were less than -0.04F or if no data (.). Recorded maximum temperature ranged from -0.04 F, several days between GA and AL weather stations, to 120.20 F on September 17, 1909 at the Millen 4 N, GA weather station. Median of maximum temperature was 80.06 F.
