As the data is used in monitoring the atmospheric condition, the threshold has been defined by the ministry to be the deviation from the long-term means.
The Ministry of Environment and Tourism and our partner organisations cannot ensure the reliability of spatial and non-spatial data layers for any particular purposes. In some cases, original data has been compiled from varous sources and the accuracy cannot be guaranteed. The Ministry of Environment and Tourism will not be held liable in any event for any consequences of using this data. Data sets may be updated without notification.
