What do we mean by real-time forecast data?
Real-time forecast data, or 'valid' data, is all meteorological information in the form of pictures, charts, text or data files for which the verification time is in the future or less than 24 hours ago. This means that it can be used to predict the weather conditions. Real-time data are also referred to as valid data. Expired real-time data are any data with a verification time ‘more than 24 hours in the past’ (i.e. data which cannot be used to forecast).
