WEATHER DATA NOTES:
The weather data used on this site is obtained from two sources. The three day forecast is from text bulletins issued by the National Weather Service.
The data displayed in the Current Conditions portion and used in disease calculations is from the NCEP Meteorological Assimilation Data Ingest System (MADIS). MADIS in turn obtains data from Citizen Weather Observer Program (CWOP). As the name inplies, CWOP collects weather data contributed by citizens. Several MGGA members maintain personal weather stations that supply data is used here (colored magenta on the map of stations). See the link to the CWOP site for more information on personal weather stations and how to become a part of the reporting network.
Occasionally lapses occur in acquiring data from the weather station network. These lapses, however seldom, will have an adverse effect on the disease predictions. The column - HRS OF DATA (second from right) - gives an indication of how accurate the alerts are in relation to the amount of data that was obtained from the weather station.
