| 摘要： | The effort to build historic climate data files expands the time and improves geographic coverage of the input data for the MEPDG. The current MEPDG climate files for Mississippi are limited to 12 weather stations in only ten of 82 counties. Only seven of the weather stations have more than eight years (100 months) of climate data. The new historic climate files use the hourly data from the 23 Automated Surface Observation System and the Automated Weather Observation System (ASOS and AWOS, respectively) and the daily data from over 100 Cooperative Observer Program (COOP). These weather databases were combined to generate a more accurate 40-year historic climate input data file for each of the 82 counties, creating over thirty times more climate input data.The study then built virtual (future) climate files by applying global and regional climate models to the 40-year historic data. Due to the long-range nature of predicting climate over multiple decades, the virtual files were limited to nine general climate zones across Mississippi. Only the temperature and precipitation data were adjusted in the virtual files. The 82 historic and nine virtual climate input data files were checked for logical errors in the files as part of the climate file development process. An example of a logical error would be a database field showing negative precipitation value. The final check of the climate data using the MEPDG program did not find any outlier data. |
