~ rost bates <br />Generally, the same independent stations selected for filling mean monthly temperature data <br />were used in the regression of daily minimum temperature. In a very few instances, independent <br />gages used in the daily minimum temperature regression differed from those used in the monthly <br />temperature regression because the stations used to fill the monthly temperature data could not <br />completely fill missing daily data. In these instances, the next closest station was used to fill the <br />daily data. The resulting range of R-values was very similar to those produced from the monthly <br />temperature regression, presented in Tables 4 and 6. The frost dates were then calculated from <br />the filled minimum daily temperature records. <br />Table 12 shows the average annual frost dates resulting from the frost date selection from <br />minimum temperature regression in the Arkansas River Basin, and shown in Table 13 for the <br />Republican River Basin. The TSTooI input command file used to fill minimum temperature data <br />and to compile the frost dates from all the stations is provided in Appendix A for the Arkansas <br />River Basin and in Appendix B for the Republican River Basin. <br />Task 76 8 2.doc 14 of 17 <br />
