5. The results from the "Data Limits Summary" were combined and analyzed in an Excel
spreadsheet, resulting in a list of climate stations with more than 60 months of data.
6. Stations with both temperature and precipitation data, from Step 4 above, were compared
to stations with more than 60 months of data from Step 2 above. Stations not in both
subsets were eliminated from the overall dataset.
The selected climate stations were reviewed to ensure the inclusion of all climate stations
indicated as "key" and filled in previous DSS efforts, if those "key" stations had temperature,
precipitation and frost date data. The selected climate stations were also reviewed to ensure the
inclusion of the climate stations historically used in the HI Model in the Arkansas Basin.
TSTooI was used to create the required climate station temperature, precipitation and frost date
files. No data manipulation was performed on the statewide climate data files. The 261 climate
stations are summarized below in Table 1.
