About Station Data
Stations with excessive missing data could lead to spatial discrepancies in several of the VIP maps that are created at MRCC. Because the maps created are national in scope, it is impractical to check stations individually and determine if the missing data would affect the output. Therefore we have implemented a screening process that is run each time the data is accessed to omit stations with insufficient data. The process has multiple criteria that could lead to a station being omitted from the maps. The first criteria is to ensure the most recent data is complete such that each station must have 14 consecutive days of data for this period and must end no earlier than the day before yesterday. A second criteria is to ensure that there is sufficient data throughout the year. A station is omitted if the missing data for the year-to-date, or any consecutive 30-day period, tops 10%.
