Notes a. The monthly means are simple arithmetic averages computed by summing the monthly values for the period 1971-2 and dividing by thirty. Prior to averaging, the data are adjusted if necessary to compensate for data quality issues, station moves or changes in station reporting practices. Missing months are replaced by estimates based on neighboring stations. b. The median is defined as the middle value in an ordered set of values. The median is being provided for the snow and precipitation elements because the mean can be a misleading value for precipitation normals. c. Only observed validated values were used to select the extreme daily values. d. Extreme monthly temperature/precipitation means were selected from the monthly normals data. Monthly snow extremes were calculated from daily values quality controlled to be consistent with the Climatology. e. Degree s were derived using the same techniques as the 1971-2 normals. Compete documentation for the 1971-2 Normals is available on the internet from: /oa/climate/normals/usnormals.html f. number of days statistics for temperature and precipitation were calculated from a serially complete daily data set. Documentation of the serially complete data set is available from the link below: g. fall and snow depth statistics were derived from the Climatology. Documentation for the Climatology project is available from the link under references. Data Sources for Tables Several different data sources were used to create the Clim2 climate summaries. In some cases the daily extremes appear inconsistent with the monthly extremes and or the mean number of days statistics. For example, a high daily extreme value may not be reflected in the highest monthly value or the mean number of days threshold that is less than and equal to the extreme value. Some of these difference are caused by different periods of record. extremes are derived from the station s entire period of record while the serial data and normals data were are for the 1971-2 period. Therefore extremes observed before 1971 would not be included in the 1971-2 normals or the 1971-2 serial daily data set. Inconsistencies can also occur when monthly values are adjusted to reflect the current observing conditions or were replaced during the 1971-2 Monthly Normals processing and are not reconciled with the Summary of the data. a.
